Acro

Acro is a boss character that appears in Kirby's Dream Land 3 and Kirby 64: The Crystal Shards. She is a large black and white killer whale (or orca) and her name is infact Orca spelled backwards.

Kirby's Dream Land 3
Acro is the boss of Ripple Field having been possessed by Dark Matter. The battle starts off in a cavern with Acro walking on her tailfins, then leaping at Kirby and crashing into the cave wall- knocking off a large rock that can be inhaled.

After taking enough damage Acro will destroy the floor of the arena so you will plunge into the water below where the rest of the fight takes place. Acro swims about spitting out various objects which Kirby must push back by blowing bubbles.

If all the Heart Stars are collected for Ripple Field, Acro will be cured of her possession and become friendly.

Kirby 64: The Crystal Shards
Acro appears again as the boss of Aqua Star possibly possessed by Dark Matter again (or a different Acro?). She is fought underwater like in Kirby's Dream Land 3 and is fought the same way with Acro swimming away from you while spawning Gordos from her mouth. She also spawns out skulls and arrows. She does certain attacks like charging at Kirby or dropping on Kirby. When she drops, boulders appear.

After being beaten in the first stage Acro faints and the cavern starts to collapse as the screen starts to scroll upward. Acro must now be fought in a vertical scrolling battle as she shoots torpedos from her mouth and swims into the background. Other enemies are in this part too.

Super Smash Bros. Brawl
