Triaformer

Triaformer is an enemy from Mega Man Zero 4. It floats in the air, moves in a circle and creates three energy stars. They then proceed to move in on Zero. Triaformer is 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.
