Thunder Wool (サンダーウール Sandā Ūru) is Sheep Man's special weapon in Mega Man 10. Mega Man launches a thunder wool-cloud that slowly rises, and a lightning bolt shoots straight down from the cloud. He can fire up to two consecutive shots. The cloud itself does very minimal damage. Pairing two clouds together will increase the lightning strike area and power. Thunder Wool is Pump Man's primary weakness - a single bolt from this weapon can not only penetrate and dissipate his Water Shield, but can also strike Pump Man in the process.

Trivia
- The Thunder Wool is considered one of the worst Special Weapons in Mega Man history by some fans. Its high energy cost does not account for the area and power of the cloud and lightning strike.
- The Thunder Wool has the same color scheme as the Thunder Beam. It is possible that it was done as a throwback to this weapon, as this color scheme has not been used for an electric weapon since the first game.
