O.B.L.I.T.E.R.A.T.O.R.

The O.L.I.B.E.R.A.T.O.R., or the Overall Liqufier of Invincibility, Basically Evil, Ready to Amazingly Tear Open Randomness, is a powerful blimp appearing on Round 600. It has 100,000 health and moves at 0.8x the speed of a B.F.B. Upon death, it spawns an Overpowered Clear Bloon with 50,000 health and the speed of a Blue Bloon, and takes away 500 lives upon escaping. It also has some truly destructive abilities:

Abilities

 * Tower Warp (Passive): Uses the 2 cannons that it stole from a Technological Terror and modified to create 5 portals on random places on the screen (though it needs to be a terrain that you can place land towers on), then puts portals under 5 towers that can be placed on land. This makes those towers warp to a random one of the 5 portals, messing up your placement. (2 towers won't come out of the same portal) If you have fewer than 5 land towers, it makes 8 portals for 4 towers, 6 portals for 3 towers, etc.
 * Mega Spawn (Passive): Uses the Bloon vents on it to spawn in 500 Bloons with 6-200 RBE each. (The game is programmed to spawn a wide variety, to make this less UP/OP)
 * Wreck: Blasts a huge missile that it stole from a B.L.A.S.T.E.R. out of the front of it, targeting and destroying a circular piece of land. The circle has a 30px radius and lasts for a minute. If a tower was in that piece of land, it gets instantly killed. Oh, and before the circle regenerates (reason: wind blows dirt in the whole), it's actually Nothingness, so you can't place anything there! Also, this attack won't hit the track.
 * Mega Heal: Spawns 5 Evolution Bloons, 50 Regrowth Yellow Bloons, and an I.A.B.O.B.E. (A 50% chance to spawn an E.V.O.L.V.E. instead) Also heals 1,000 health.
 * Oliberate: Its ultimate ability, so ultimate that I made an entire SECTION for it...

Oliberate
Oliberate is the ultimate (and pretty obvious) ability of the O.L.I.B.E.R.A.T.O.R. It has several phases:

Phase 1 (Explosion)
The O.L.I.B.E.R.A.T.O.R. launches 5 missiles out of the modified 2/4 Tack Shooter on its back that have a 0% chance of evasion (because they home in on towers) in a star shape, which home in on 5 random towers. On contact with a tower, the missile explodes, dealing 35 HP damage and exploding in a Big One radius. The explosion deals 20 HP damage. 2 missiles won't target the same tower unless you have 4 or fewer towers. And don't try selling the targeted towers, the missile targets another tower. If you don't have any towers, the missiles fly off the screen. 3 seconds after using this, it goes to Phase 2.

Phase 2 (Dart Swarm)
The O.L.I.B.E.R.A.T.O.R. blasts a stream of darts out of the front of it in a random direction using stolen Dartling Guns lasting for 5 seconds. The stream of darts is 75px wide. It deals 25 damage PER SECOND, and as opposed to other laser attacks, it only has a 5% evade chance! (Due to its width) 3 seconds after the laser wears off, it goes to the third and final phase...

Phase 3 (Attack-O-Combine)
The O.L.I.B.E.R.A.T.O.R. does all of these at once:


 * Puts portals under 3 random towers, changing their location (the portals have the same mechanics as Tower Warp)
 * Spawns 300 Bloons with 4-100 RBE
 * Destroys a circular piece of land with a 15px radius that prevents tower placement there for 40 seconds, and any towers that were there get instantly killed
 * Heals 1,000 health
 * Launches 3 homing missiles in random directions that home in on towers with the same mechanics of the missiles in Explosion, but the explosion is a 3/2 Mortar Tower instead of a 4/2 one, the missiles deal 25 damage instead of 35, and the explosion deals 15 damage
 * Blasts a stream of darts in a random direction which is 40px wide and lasts for 3 seconds

And...that's the end of Oliberate

Trivia

 * Attack-o-combine is a reference to Plants Vs Zombies Character Creator.
 * However, Tower Warp isn't a reference to Portal or Portal 2.
