Sola 0

Sola 0 (ソーラ・０) is a flower-like enemy from Mega Man 10 that charges solar energy to fire a solar ray. They are invincible while charging energy. They appear in Solar Man's stage, Wily Castle 2 and Special Stage 3. In Hard Mode they also appear in Pump Man's stage.

Trivia

 * Its name is probably a pun of "solar ray", as zero is written as "rei" (零) in Japan.
