T.H.U.N.D.E.R

T.H.U.N.D.E.R (Terrifyingly Horrific, Unjustly Notorious, Destructive, Electric Ruler) is a M.O.A.B. class Bloon that appears on round 300 on 1000-round impoppable. It then appears on every 75 rounds after that. It has 600,000 health and moves at the speed of a green Bloon. It has Camo and Lead properties. It is immune to Ninja Monkey's Counter Espionage, and (I am going to put something here but I need to get special permission first.). It not only has an immunity to lightning attacks, but HEALS when hit by it. Every so often when it's hit by a lightning attack, it will say, "Why, Thank You!" in a rather menacing voice that can stun unupgraded towers within its range (it's range is that of a 0/0/0 super monkey).

Triva

 * The reason unupgraded towers are stunned by it's sarcastic comment when healed is because it can see the fears of unupgraded towers and project them onto itself like a Boggart. < Link to Boggart page on harry potter wiki
