Triaformer

Triaformer is an enemy from Mega Man Zero 4. It floats in the air, moves in a triangular formation and creates three energy stars. They then proceed to home in on Zero depending on where he is standing. Triaformers are found in Mino Magnus's, Popla Cocapetri's, and Pegasolta Eclair's stage.

Trivia

 * The Triaformer closely resembles Volt Catfish's Triad Thunder from Mega Man X3, but shoots energy shots instead of lightning.
