Mega Man 7/Weapons and damage chart

Burst Man
Burst Man was created to guard a chemical plant, but was stolen and modified for combat by Dr. Wily. He stores explosives and soapy liquids inside his body which are used for generating bubbles, as well as creating his Danger Wrap, a bomb wrapped inside a strong bubble. The liquids in his body make him vulnerable to sudden changes in temperature, forcing him to expel several explosives.

Cloud Man
Cloud Man was originally a weather control robot before he was stolen by Dr. Wily to have his control over lightning amplified. He has no legs, instead he hovers above the ground using an anti-gravitational device. He can charge himself up with lightning to render him invincible to all attacks, then direct it onto the ground. He can also stir up strong winds and heavy rainfall. Cloud Man has great difficulty getting out of bubbles, and can only wait helplessly if he is encased by Danger Wrap.

Freeze Man
Freeze Man used to be a prototype of a robot that runs on green energy. He is able to split normal room temperature into high and low temperatures, the former is used to power his body while the latter is used as his weapon, the Freeze Cracker. Freeze Man can be disrupted with orbiting junk, but this weakness does not affect him as badly as other robot masters.

Junk Man
Junk Man was created by Dr. Wily out of used robot parts to help him search for parts that can be used for robot masters, but was turned into a robot master himself after Dr. Wily noted his strength and resilience. He can generate electromagnetic forces that let him manipulate junk metal, using it for his attacks. A powerful jolt of electricity can disturb the electromagnetism that holds his body together, causing him to fall apart temporarily.
