D.I.O.

The D.I.O. (Deadly Impertinent Obliterator) is a blimp that first appears on Round 305, and every 305 rounds after that. It has 325,000 HP, and moves 0.00001x the speed of a P.I.N.G.A.S., and even has the same immunities of P.I.N.G.A.S.. It spawns 4x P.I.N.G.A.S. upon its death. It also resembles a golden B.A.D..

Attacks
ZA WARUDO: All towers stop attacking for 10 seconds. Cooldown: 45 seconds. Taunt: "ZA WARUDO!"

It was me, D.I.O.!: Disguises itself as one of your towers for 5 seconds, and will attack your other towers while it was disguised. After the 5 seconds are up, D.I.O. will go back to where it was on the track before it used this ability. (Fortunately, this ability doesn't work on Special Agents.) Cooldown: 60 seconds. Taunt: "You were expecting (name of tower it disguised itself as), but it was me, D.I.O.!"

ROAD ROLLER DA: A giant road roller falls from the sky onto one of your towers, dealing 100 damage and stunning that tower for 5 seconds (if that tower survives the road roller falling on it). Cooldown: 30 seconds. Taunt: "ROAD ROLLER DA!"

WRYYYYYYYYYYYY: Yells "WRYYYYYYYYYYYYY", which stuns all towers for 5 seconds. Cooldown: 20 seconds

Stand Summon: Summons a fortified version of itself, which has all of D.I.O.'s attacks (except for Stand Summon). Fortunately for you, the stand moves 10x slower than D.I.O. itself, and it doesn't spawn anything when popped. D.I.O. can only use this once.
