User:Squiddington/The Stronghold

The Stronghold is a fairly large AI-controlled boss that occasionally spawns in the Pentagon Nest if no other boss is currently in play. When a Stronghold spawns in the Pentagon Nest, all polygons in and nearby the nest will despawn.

Design
The Stronghold has a purple square base decked out with many small barrels protected by shield-looking contraptions from all sides, similar in appearance to the Reflector shields (Reflector Tank was made by ScribbleMasterer, and it's a pretty cool tank at that.) which protect from all sorts of weaponry. It has four abnormally large Annihilator cannons, one in each cardinal direction that it uses for enemy spawning and powerful attacks.

Phase 0
When it spawns, it will spawn as a grey immobile square. Unless six players arrive near the Stronghold, it will despawn and be replaced with another boss in twenty minutes. All shots directed at the tank will be deflected, but will not do damage back to other player tanks.

Phase 1
Once six players arrive, spiked walls will rise up and surround the Stronghold. The tank itself will start to vibrate and enlarge, while many barrels will start to slowly come out, including Reflector shields. Hordes of grey Basic Tanks will exit the Annihilator cannons and begin to chase and constantly shoot at the nearest players. These tanks are pretty weak but may overwhelm a single tank if not prepared. When all Basic Tanks have been killed, it will move to its second phase.

Phase 2
When this phase starts, one of the Annihilator cannons shoots out a very large bullet that leaves behind slow moving smaller bullets behind it and to the sides of it as it moves. When the big bullet hits a wall, it will explode into three rings of bullets. These bullets will also rebound off the shields as well. Randomly chosen Tier 2 Tanks will now exit the large cannons and begin to flood the area, although at a slightly lower spawn rate. Killing all spawned Tier 2 tanks will bring in another horde of slightly stronger Basic Tanks and will start Phase 3.

Phase 3
The Stronghold will now begin to rotate and shoot chaotic spreads of small bullets from its smaller barrels, occasionally shooting Annihilator bullets out of all the cannons that don't explode and leave behind bullets for at least 30 seconds. Tier 3 Tanks will now start to spawn out of the big cannons once it has stopped shooting and rotating, at a lower spawn rate than the Tier 2 tanks. Basic Tanks will also flood out again after all Tier 3 Tanks are defeated and will start Phase 4

Phase 4
The final phase before it can be attacked, it will shoot a stream of 5 Annihilator bullets with slight spread out of a random cannon that explode into rings of bullets. it will alternate which cannons it shoots out from for 30 seconds and it will then start to spawn Tier 4 Tanks. Tier 2 Tanks may occasionally flood out of the big cannons to aid the larger tanks. Once all Tier 4 Tanks are dead, the final phase is activated.

Final Phase
It will begin to slowly move diagonally, bouncing off walls and slowly rotating. It will damage its Reflector Shields once it rebounds off a wall, rendering it weak and unable to work properly. The tank itself will shoot chaotic bursts and spreads of small bullets while Annihilator cannons will randomly shoot out large bullets that explode into three rings. Basic Tanks and Tier 2 Tanks will often swarm out of the Annihilator cannons when they're not firing as well. Once killed, it will explode into a mass of bullets as a last ditch attempt to kill the opposing tanks.

 * No clue why I made this boss idea so long, but yeah.
