Violet. Strong. Stealthy. Those words describe Octrax, the leader of the eight-sided polygons. He is the eighth and last Disciple to be created, and following in his brothers' footsteps; he put in motion the creation of defensive polygons we know as Nest Defenders. Like the others, he resides in a fortress where he oversees as many of his octagon subjects as he can. Records show his massive involvement with the new generation of polygonal protectors, starting with the Vanguard. Since then his big success is the ability to utilize cloaking. Aside from his genuine support for Pentavian, much else about him is very obscure. Also, he tends to lurk in the shadows...

Overview

Octrax is one of eight Disciples of the Polygons. He is technically the youngest of the Disciples, since he was created last, but is considered just as powerful as the others (and more mature than some of them.) His fascination with technology had lead to many great innovations for the protectors of the nests, bringing forth of the ability of stealth, disorientation, and the perfection of ambush. Within The Old Era, he was shown to be one of the most formidable Disciples, almost rivaling Pentavian at one point. His battle tactics were fierce and had driven out many Tank Empire-controlled provinces.

He represents the Octagons and every defender associated with them. Octrax, along with the other Polygon Disciples, is located in the heart of his Edifice. He is located on the climbing heights of the Neverest Mountains, where rumors spread about him being involved with the man in the mountain... His complex is filled with Octagon-based inhabitants and the keepers that await any intruders. They will be fought first before facing down the ruler of them all.

Design

Octrax is a purple octagon with two smaller octagons bound together with smaller octagons to the body, like the other Disciples. On the bottom of his body is a spawner. One of the smaller octagons has a sledgehammer-like mallet with gold accents on the faces and handle. The other hand has a short dagger weapon. Said hand has armor on the area where the dagger is held by the octagon hand. Octrax's main body has a gray helmet that barely covers the top of his "head" and has two gold "wings" extending to the left and right, think of it as the gold thingies on DC superhero Flash's costume. The middle of the helmet has a trapezoid protrusion from the bottom edge to make room for an octagon gem like the other Disciples. Octrax also has octagon-shaped barrel gray armor around his body and hands.

Stats

Octrax has a total HP of 65,000. He has a 40% baseline resistance to damage in Phase 1, which is reduced to 10%, even when under the Broken Debuff. Octrax regenerates very slowly, 4 HP every second for all parts, regeneration does increase by 500% if left alone for over two minutes (though it's rare for that to happen). His body deals 60 HP of body damage, 40 for his hands.

Octrax can summon various enemies like other Disciples, ranging from octagons and Crashers, bosses like the Vanguard and Pulsar, Spreader, Collider, Lurk, Vortex, or even Umbra. He has an ability to summon many Nest Defenders as well. In Phase 2, where his hands lose their weapons, Octrax can summon boss entities.

Octrax's Weapon Swaps

The various weapons that Octrax's left weapon can become.

Octrax can swing his hammer around to block bullets and other ammunition, sending it back towards players. The hammer can also be used to hit players for medium damage, dealing a bit of knockback to them. He can also use his Slayer weapon like a short, high-damage dagger, a longer medium-damage short sword, and an extended form with barrels as a bullet storm weapon. Each time when changing forms, the old form retracts back in completely, and the new form extends out.

The bottom spawner constantly spawns 2 Crushers, 2 Decontrollers, 2 Phasers, 3 Semi-Crushers, and 3 Spiralers, in that order for every 2 seconds. Size is randomized. Rarely it will release a storm of 12-27 of one Crasher type. An octagon is also released occasionally, there being a 50% chance after the Crasher pattern to spawn one. Very rarely, Octrax will spawn 4 Assassinators (10% chance after the Spiralers, octagons may spawn afterward like normal). There is a limit of 120 Crashers of any type and 70 octagons at once at any time. Neither limits apply to octagons and Crashers used in Octrax's attacks.

ZathsuGrav Weapon Octrax Shadow Hammer

Octrax's massive Shadow Hammer. You'll see it coming, but you won't hear it...

Octrax has some magical powers (which become very prevalent in Phase 2), but otherwise relies mostly on his bulkiness and stealth, which is unusual given the first characteristic is not usually associated with the second. He can summon polygons, though, like throwing Alpha Octagons at players and directing his Crashers into formations. Mostly though, he lurks in the shadows and body slams into players with his weapons. His attack style is derived around surprise and hefty damage while summoning decent amounts of enemies to distract his foes.

The Fight

Phase 1

During this phase of the battle, he is in the center of the arena, staying still as more players join in. After the transmission ends, Octrax then stands up and speaks his monologue. Both players and Octrax himself would not attack until he finishes. His first attack will block the exit and is only used once. 50 Octagons are summoned to block the exit.

Octrax is invulnerable during Phase 1, and only when both his hands' HP reaches 0 will cause Octrax to enter Phase 2. The hands that are "destroyed" loses all of its weapons and becomes invulnerable, but useless. Attacks that require the weapons will be disabled.


  • Wall of Eight: Octrax summons about 40 Octagons to block the exit. They link together and form an impenetrable but bouncy wall. Tanks that try to exit from the inside will get bounced back, while tanks that try to come in will be bounced away as well. Damage is not sustained by those who are bounced.

Watch your back...

  • Slide: Octrax's main form of movement in this phase. Octrax moves around in the four cardinal directions and along diagonals. He can move during attacks unless otherwise stated.
  • Bell of Doom: A bell sound can be heard as Octrax vanishes in a blur. He moves so fast that he's almost invisible, then the bell sounds again, and Octrax stops near a player, then blasts them with the Slayer weapon and anything else that happens to be in the way.
  • Linear Strike: Octrax summons a line of 5 Beta Octagons, then summons one Alpha Octagon. He hammers the Alpha Octagon into the line of octagons, sending the last one in the line flying outwards like a Newton's Cradle. Octrax continues hammering very quickly until the Alpha Octagon has been sent flying. Octagons bounce everywhere up to 5 times, dealing medium damage to anything that's hit. If they hit each other, that will not count as a bounce.
  • Billiard Strike: Similar to Linear Strike, but the octagons are arranged in a triangle, and there are 10 of them. When Octrax smashes the Alpha Pentagon, it flies into the triangle of octagons, sending all 16 flying. Same bounce mechanics apply.
  • Twilight Summon: Octrax momentarily stops moving and raises his left hand as it glows brightly. A small deep-blue portal appears randomly in the arena, releasing many different waves of Crashers below. He joins all existing similar Crashers into a group, then directs it around like a swarm of Clone Drones, controlling them like a Necromancer with the repel function. This applies to only Crushers, Semi-Crushers, Decontrollers, and Phasers. Summoned Assasinators and Spiralers will behave on their own. All are summoned with a 33% chance of being a larger version. During this attack, Octrax will periodically move around, either swiping his Slayer or his Shadow Hammer at nearby players. Several waves may happen.
    • Heavy Crush: Summons a wave of 14-22 Crushers.
    • Phase: Summons a wave of 18-31 Phasers.
    • Light Crush: Summons a wave of 25-45 Semi-Crushers.
    • Shadow Militia: Summons a wave of, 15-28 Assassinators.
    • Whirlpool: Summons a wave of 28-52 Spiralers.
    • Oil Slick: Summons a wave of 16-27 Decontrollers.
  • Cloak and Dagger: Octrax vanishes and moves around invisibly, rushing to nearby tanks and dishes out 2-5 strikes per tank, with low damage per strike but adding up with each strike. Used 6-14 times on targets. Octrax uses the Slayer weapon in its extended form without barrels here.
  • Missile Turret: Octrax extends the Slayer weapon with its barrels if it isn't already extended, and fires off 20 homing missiles (War Machine variety) that track down players. Missiles have 80 health and deal 60 damage on impact.
  • Supernova: Octrax spawns a mixed group of 42-60 (Phasers, Semi-Crushers, and Crushers) Crasher variants and gathers those and all existing Crashers in one spot, then sends them out at an incredible speed, the Crashers dealing low damage to a good deal of tanks in the battle due to the number of players fighting Octrax.
  • Shockwave: Octrax pounds the ground with his hammer, sending out a rippling shockwave in the ground in a radial pattern (like when you throw a rock into a pond.) Tanks hit by the shockwave, which dissipates after 65 background tiles in radius, are dealt damage scaling from how close they are to Octrax when he pounds the ground. It's medium-high up close and low far away.
  • Bulk Up: Octrax's body shines white, and he receives Armored for the next 45-60 seconds while increasing his base movement speed by 25%. Only happens five times during Phase 1, it happens every seven attacks.
  • Hammer Punch: Octrax shoves his hammer weapon bluntly into a tank, dealing medium damage and knocking back slightly. He then will attempt to whack tanks with one of the actual hammer sides five times, dealing high damage and healing himself for the damage dealt. Not used more than four times per fight in this phase, happens every eight attacks.
  • Cyclone: Marks the transition to Phase 2 once both of his arms lose their weapons. Octrax's arms detach from his body and rotate around him as he charges tanks to body-slam them and deal high damage if anything comes in contact with his arms. His head is armored during this attack.

Phase 2

When Octrax's hands are disabled at 43,600 HP, he enters Phase 2. Octrax moves faster and teleports around to disorient his enemies using Slide II. His baseline damage resistance is reduced to 35%. Bullets fired at the hands will go through them. However, he retains use of his hammer, but his use of it is limited (the only attack that uses it is Hammer Punch.) The frame armor around his body, hands, and arms also shatters and disappears.

Octrax can now summon bosses such as the Pulsar, Vanguard, Spreader, Collider, Lurk, Vortex, and Umbra. All of these bosses will reward EXP excluding the minions.

During a boss summon, Octrax will be invulnerable until boss/bosses dies. He cannot attack while a boss is in session. After the boss(es) die, Octrax will resume attacking until the loss of 7,200 HP has been reached. For every milestone of 7,200 HP lost, Octrax will summon a boss or multiple bosses as the following:

Boss Spawning Order:

  • At 38,600 HP: Pulsar.
  • At 31,000 HP: Collider + Two Vortexes or Collider + Two Vanguards or Collider + Two Lurks.
  • At 23,400 HP: Umbra + Spreader + Pulsar.
  • At 15,800 HP: Two Colliders + Three Vanguard or Two Spreaders + Three Vanguards or Two Colliders + Three Lurks or Two Spreaders + Three Lurks or Two Colliders + Three Vortexes or Two Spreaders + Three Vortexes.
  • At 8,200 HP: Two Umbras + Two Spreaders or Two Umbras + Two Colliders or Two Umbras + Three Pulsars or Three Pulsars + Three Vanguards.
  • At 600 HP: Umbra + Collider + Spreader + Lurk + Vortex + Vanguard + Pulsar.

Attacks

During the between sessions of the boss summoning, Octrax will perform these attacks randomly. If Octrax reaches a 7,200 HP mark, he'll become invulnerable and wait for the attack to be finished.


  • Slide II: Octrax's main form of movement, moving around in the four cardinal directions and along diagonals. He can move during attacks unless otherwise stated, and now teleports randomly at random intervals and moves 50% faster.
  • Bell of Doom II: A louder and deeper bell sound can be heard as Octrax vanishes in a blur. He moves so fast that he's almost invisible, then the bell sounds again and Octrax stops near a player, then body-slams them to deal very high damage.
  • Linear Strike II: Octrax summons a line of 16 Beta Octagons, then summons two Alpha Octagons. He body-slams the Alpha Octagons into the line of octagons, sending the last one in the line flying outwards like a Newton's Cradle. Octrax continues hammering very quickly until the 2 Alpha Octagons have been sent flying. Octagons bounce everywhere up to 7 times, dealing medium-high damage to anything that's hit. If they hit each other, that will not count as a bounce. Octagons also move 20% faster than before.
  • Supernova II: Octrax spawns a mixed group of 68-102 Octagon Crasher variants and gathers those and all existing Crashers in one spot, then sends them out at an incredible speed, the Crashers dealing low-medium damage to a good deal of tanks in the battle due to the number of players fighting Octrax.
  • Shockwave II: Octrax jumps and smashes the ground with his body, sending out a rippling shockwave in the ground in a radial pattern (like when you throw a rock into a pond.) Tanks hit by the shockwave, which dissipates after 85 background tiles in radius, are dealt damage scaling from how close they are to Octrax when he pounds the ground. It's high up close and still low far away, however, the damage is increased from the original Shockwave.
  • Hammer Punch II: Octrax shoves his hammer weapon bluntly into a tank, dealing medium-high damage and knocking back slightly. He then will attempt to whack tanks with one of the actual hammer sides six times, dealing high damage. Doesn't heal him anymore, so it can be used as much as needed.
  • Twilight Summon II: Octrax momentarily stops moving and raises his left hand as it glows brightly. A small deep-blue portal appears randomly in the arena, releasing many different waves of Crashers below. He joins all existing similar Crashers into a group, then directs it around like a swarm of Clone Drones, controlling them like a Necromancer with the repel function. This applies to only Crushers, Semi-Crushers, Decontrollers, and Phasers. Summoned Assasinators and Spiralers will behave on their own. All are summoned with a 33% chance of being a larger version. Octrax periodically move around, occasionally pursuing individual tanks with his Shadow Hammer for the duration of this attack. Several waves may happen.
    • Heavy Crush: Summons a wave of 21-32 Crushers.
    • Phase: Summons a wave of 25-37 Phasers.
    • Light Crush: Summons a wave of 32-58 Semi-Crushers.
    • Shadow Militia: Summons a wave of, 19-34 Assassinators.
    • Whirlpool: Summons a wave of 37-62 Spiralers.
    • Oil Slick: Summons a wave of 20-31 Decontrollers.
  • Border Wall: Octrax shines a metallic gray, becomes Invincible, and spawns an insane amount of Crashers (250+) that form a wall in front of him. They don't attack, and tanks have to destroy the wall of Crashers to resume fighting Octrax. Once 90% of the wall is destroyed, all remaining Crashers become active again and Octrax returns to normal.
  • Collateral: Octrax summons 25 normal Octagons, and controls them like drones. Controlled octagons have the same health and body damage values, and move as fast as a Large Crasher.
  • Castle Towers: Octrax places down 8 Octagon Defensive Turrets, Beta Octagons with Dominator Auto Turrets atop them in an octagon formation surrounding him. They have 1200 health and fire as fast as a normal Dominator. Bullets have infinite penetration and the damage of a Destroyer's, like normal Dominator bullets do.
  • Entralink: Octrax's helmet "wings" flash gold and Octrax releases a gold energy wave emanating from his body, inflicting players with Confused and Dazed for 5 seconds.
  • Electric Hail: Octrax summons down 8 purple lightning bolts to strike areas with the highest concentrations of players. Purple octagon targets will appear 2 seconds prior to where the bolts will strike; as a result, there is not much time to avoid them, but luckily the hit radius is tiny. Players struck receive low damage and Paralyzed for 3 seconds.
  • Revolution: Octrax spins around until he becomes a blur and disappears completely. While invisible, he rams into players while spinning like a tornado, dealing medium-low knockback and sending them flying in a random direction. This lasts for 8 seconds.
  • Octothorpe: Octrax summons 16 large Semi-Crushers to form into a "#" configuration. He directs it to move at the nearest player. Upon losing two Semi-Crushers, the rest of the formation disintegrates.
  • Steam Seeker: Octrax throws a smoke bomb in front of him, and in the mist, he vanishes completely. When the smoke clears, he is nowhere to be seen, but 8-13 groups of Phasers or Crushers (3-5 in each group) spawn out of nowhere in random places throughout the room, and seek out players. Octrax will appear 20 seconds later, body-slamming the tank with the lowest health.

Death Phase

When Octrax reaches the 600 HP mark, and after the bosses are defeated, Octrax initiates his final phase. He will perform a normal Collateral attack and summons a dense wave of 24 Alpha Octagons that slowly expands out from him and back continuously. Octrax will actively be moving around trying to avoid any form of enemy ammunition, while the expanding wave of Alpha Octagons will follow. He will also perform Rotation over and over, but resting with Broken for 3 seconds and the attack lasting for 5 seconds instead. The Alpha Octagons have their usual health.

The bouncy wall of 50 octagons created from the beginning of the fight suddenly breaks apart and become normal octagons that are being controlled by Octrax as extra drones. However, destroying Octrax himself is the only way to win the fight. Just deal enough damage, and it's over.

If every tank present during Octrax's final moment has died, he will remain in the arena, tired and warn out from his use of attacks. He remains silent as the screen fades.

However, if Octrax's HP finally reaches 0, he kneels down, and white cracks begin forming all around his body, any octagon in range around him starts to lose their color, turning into shades of gray. Octrax then suddenly vaporizes with a white flash on the screen, leaving only the helmet behind on top of a pile of ashes. All octagons and polygons associated with them with a huge radius around the death of Octrax will have halved HP and resistances. Any octagon-based bosses/mini-bosses that were present near the fortress where Octrax has been defeated will greatly reduce in HP and Resistances; Superior Octagon nests will stop spawning octagons for a long time around its destruction area...

Quotes

Introduction During Battle

  • "Fretful you are to barge into this place, little Tanks. I am quite surprised. Yet you all should have known what comes next. Of course, I am much too big to not be seen. I can be considered to be quite the burly one. I understand that my magical abilities are limited. Come on now, make your first shot. You made great lengths assassinating my Paramarchs... how am I suppose to be any different? I recommend just to ignore me and go straight to the plains. You will have plenty of victims to slaughter. --- Oh. I see. Afraid? Or determined to eradicate me once and for all. This will be an easy battle for you. But let be known: I can see what you're up to."

Trivia

Octraxoriginalsketch

Octrax's original sketch, with the treads.

  • Octrax's main physical traits are being bulky and stealthy, two traits that don't usually go together. But it works fine here, so shush.
  • His original design had 3D treads on the bottom of his body, but it was ultimately decided that the treads were too hard to replicate in the Diep.io art style.
  • This symbol (#) is known by various nomenclatures in different applications as the pound sign, number sign, hash, hashtag symbol, octothorpe, octothorp, octatherp, octothorp, comment sign, cross, hex, crosshatch, space, sharp, square, fence, mesh, flash, grid, pig-pen, tictactoe, scratch (mark), (garden) gate, hak, oof, rake, crunch, punch mark, sink, corridor, capital 3, and waffle. Here, when used in Octrax's attack, it is called an octothorpe. And that is your interesting fact for today.
  • Many of Octrax's bosses have an invisibility ability, making fighting them difficult due to the occasional inability to determine their location.
