Thunder Bolt, known as Thunder Strike (サンダーストライク Sandā Sutoraiku) in Japan and in the English version of Mega Man: The Power Battle, is Cloud Man's special weapon. 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 and split on impact with an enemy, traveling upwards and downwards. The Thunder Bolt can also be used to activate some of the machines in Junk Man's stage. Thunder Bolt is also usable in the dark hallway in Shade Man's stage because the Thunder Bolt is a ball of electricity that emits light, acting as a second alternative to illuminate the corridor of the player doesn't yet have the Scorch Wheel.

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 (8 units). It will also supercharge Turbo Man, making him temporarily invincible as he drives around his chamber. If the Thunder Bolt is shot on the cloud platforms on Cloud Man's stage, it will cause a thunderstorm in the platform and the electricity can hurt Mega Man.
