Thunder Dancer

"An electrical weapon. Bullets will automatically ricochet to the next target."

- In-game text

Thunder Dancer (サンダーダンサー) is what X gets from defeating Gigabolt Man-O-War in Mega Man X8. It's a short range (but strong) bolt of electricity. The charged up version is still short range, but it sends out three bolts at once. This weapon is Avalanche Yeti's weakness. 

Trivia

 * This weapon resembles to a similar weapon that the original Mega Man obtained from Mega Man V.
 * Interestingly, if Burn Rooster is struck with Thunder Dancer (or any of the other electric weapons), he powers up considerably.
