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 starts at it's weakest form 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. It will also reduce the size of his Solar Blaze.

Trivia

 * Solar Man's sprite differs greatly from his official artwork, as the sprite lacks a visible head, his hands and feet are a different color, and some minor color changes due to graphic limitations that had to be met to match the NES's incapabilities.
