E.L.E.C.T.R.O.

The E.L.E.C.T.R.O. ( E lectrified L iving and E nchanted C ounter-part of the T ormentor R ay of O bliteration) is another MOAB-class bloon. It has 7800 HP, realeasing 100 Shock Bloons and 40 Shining Bloons, and is immune to electric or light based attacks. It moves as fast as a red bloon and first appears at round 87. It looks like a yellow M.O.A.B. and these are its abilities: It has a 35% chance of realeasing a Plasma Ball.
 * XS Shock Cannon: Shocks 2 random towers for 3 HP damage, can cause chain reaction with up to 2 towers.
 * Mechanical Surge: 4 random half-robot, half-monkey towers and machines recieve 6 damage and are stunned for 7 seconds.
 * Electro-laser: Shoots a laser in a random direction that deals 5 HP damage. This ray is only 7px thick but pierces INFINITE towers.

Second Form
The E.L.E.C.T.R.O. comes back at round 114! He now has 14600 HP and spawns twice as much bloons but still moves as fast as a red bloon. He still has the same immunities and has new and enhanced abilities: This form also has a 85% chance to realease 1 Plasma Ball, 55% chance for 2 Plasma Balls, and 25% chance for 3 Plasma Balls.
 * Stormy (Passive): If a tower is 196px away form the blimp or closer, that tower will suffer 1 HP damage every second and can cause chain reaction with another tower. You can know when that tower is 196px close because there are lightnings that come from the blimp and only reach a 196px diameter. The screen is also darkened.
 * XS Shock Cannon v2: Shocks 3 random towers for 8 HP damage and can cause chain reaction with up to 3 towers.
 * Universal Mechanical Failure: 5 random half-robot, half-monkey towers and machines recieve 9 damage and are stunned for 9 seconds.
 * Charged Laser: Stops moving and starts charging a laser shooter that this blimp contains under it. 4 seconds after starting charging, the blimp will shoot 3 laser in random directions
 * Possession: All of a sudden, a random machine/robot gets stunned and darkened. Then some kind of black shadow comes out of it and goes into an organic (non-Super Monkey) tower. That tower will then start attacking YOUR towers, it shoots its projectile (whatever it is) every 1.2 seconds dealing 6 HP damage to everything in the tower's range (and ingores 50% of AD!). This effect (both the stunned and possessed towers) lasts until you kill the E.L.E.C.T.R.O.. It can only use this attack once.

Trivia

 * Possession is an obvious reference.
