Thunder Bolt

Thunder Bolt is Cloud Man's power. This weapon shoots a ball of electricity straight from where you shot (though due to a program glitch, it tends to go down a bit with you when you fall). It can not only zap some enemies--especially Junk Man--but in Junk Man's stage, you can activate some of the machines with it.

Warning: Do NOT use this 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.

Trivia

 * The Thunder Bolt is called Thunder Strike in Mega Man: The Power Battle and the Japanese version of Mega Man 7.
