Fanon:The Nightmare of All Polygons

''This is the machine that all polygons fear... They are terrified by it... They flee before it... And since the dawn of time, this hulking behemoth of a bot has been exterminating them, believing that all polygons were parasites of this world. Oh, the cries for help. The shrieks of horror. Even the Polygon Mother feared it, to an extent that she herded her surviving children to a place known as the Arena. Yes, the very same arena that us tanks now inhabit. Said arena laid untouched by the mechanical menace for aeons, as The Nightmare of All Polygons searched and searched for more parasites to slaughter. Until, one day, it found them. The very thing all polygons feared, the thing that haunted their dreams, has became a reality. A truly terrible reality. And all polygons will be eternally grateful to those who slay, or at least disable this dreaded droid...''

The Nightmare of All Polygons is an Event Boss I made for the Extended Tale of Diep. It can spawn absolutely randomly in any gamemode except for Maze. Created by The Tidal Wave.

Appearance
The Nightmare of All Polygons is positively huge. It is so large that it takes up 1/4 of a standard FFA arena. It is composed of 9 circles that resemble the components of the War Machine, the thing the creator of this monstrosity intended to emulate. On the center of the large circle is a turbine that takes up most of the circle. Meanwhile, on the smaller circles are, respectively:
 * 1) 5 tentacles that are placed to resemble a Pentashot. These tentacles can lengthen to any desired length and stick to anything they touch. Things that are stuck to the tentacles will receive constant damage.
 * 2) A chainsaw drawn in Diep.io style.
 * 3) 20 auto turrets that fire in synchronized patterns.
 * 4) A stereo system that constantly blasts out different-sized bullets. They all do the same damage, however.
 * 5) A tesla coil.
 * 6) A grappling hook.
 * 7) An Annihilator barrel.
 * 8) 8 Battleship spawners evenly spaced out.

Attack methods
This boss is neutral to all tanks. It entirely ignores you if you are under level 30, but you will be entirely unable to hurt it too. Polygons are it's main target, and it will stop at nothing to kill them all. The center turbine passively sucks in everything, and touching it spells instant doom. While this is alive, no polygons will spawn. Each small circle has a different attacking style, listed below: Once the Nightmare's massive health pool drops below 1/4, it starts to attack tanks, it's AI thinking that us tanks are helping the polygons.
 * 1) The tentacles will extend and grab a polygon each and do damage to them. If the polygon in question is an Alpha pentagon, the tentacle will "feed" the pentagon to the main turbine.
 * 2) The chainsaw slashes at nearby space.
 * 3) The Auto turrets fire at nearby polygons at the firing rate of a gunner.
 * 4) The stereo system blasts bullets that form many different shapes, mostly musical symbols. When the Nightmare has 1/8 health however, they spell words like "KILL" or "DESTROY".
 * 5) The tesla coil shoots lightning that pierces through everything. The lightning goes on indefinitely in a straight line.
 * 6) The grappling hook grabs polygons and feeds them to the turbine.
 * 7) The Annihilator barrel fires lasers at polygons.
 * 8) The Battleship spawners spawn protectors that have infinite lifespan to track down polygons. One protector can kill 3 polygons before disappearing.

Rewards
As a tribute from the polygons to us, all tanks who did at least 1000 damage to The Nightmare of All Polygons will get (200*damage dealt) XP.
