Thunder Bolt

Thunder Bolt, known as Thunder Strike (サンダーストライク) in Japan and in the English version of Mega Man: The Power Battle, is Cloud Man's power. This weapon shoots a ball of electricity straight forward (though due to a program glitch, it tends to curve downward if fired while falling). It travels through walls, but if it does not destroy an enemy on impact it will split and travel upwards and downwards. The Thunder Bolt can also be used to activate some of the machines in Junk Man's stage.

This weapon will electrocute Junk Man, preventing him from using his Junk Shield and magnetism attacks if used consecutively. Conversely, if the Thunder Bolt is used on Spring Man, it will cause him to become magnetized, and he will pull Mega Man toward him and toss him upward, causing some serious damage. It will also supercharge Turbo Man, making him temporarily invincible as he drives around his chamber.

Also if you shoot the cloud platforms on Cloud Man's stage,it will cause thunderstorm in the platform and the electricity can hurt Mega Man
