Solar Man

Solar Man (ソーラーマン) is a Robot Master from Mega Man 10. He attacks by shooting energy straight out of the top of his head. He is also able to block and absorb attacks with his artificial sunlight to increase the power of his attacks.

Solar Man worked in a sunlight research lab before he went berserk from Roboenza. In his spare time he developed a "Solar Workout" plan which has experienced small success.

Strategy
Solar Man jumps around the room firing Solar Blaze from his head. He occasionally tilts his head towards you, aiming to absorb your shots in order to power the Solar Blaze

On Easy Mode, his Solar Blaze is always at it's weakest form regardless of whether or not it absorbs shots and he only throws one fireball at a time.

On Hard Mode, his Solar Blaze is always at it's most powerful form, and he also has a new attack in which he shoots three Solar Blazes into the air that fall at your position at the time.

The best weapon to use is Water Shield, in that not only does it cancel out his attacks, but if used properly can hit him multiple times.

Trivia

 * In his official artwork, Solar Man has a head, but his sprite just shows his eyes.
 * Because of color limitations, his green center piece is orange in the sprite.
 * Water puts out fire, hence Solar Man's weakness.
