Piriparee

Piriparee (ピリパリー) is an humanoid combat robot enemy resembling a Sniper Joe that appears inside the Wily Star in Mega Man V. He has an older brother named Biribaree. These enemies attack by charging up intense amounts of electricity within their bodies, being temporarily invincible to all attacks while doing so, and then firing off a bolt of electricity. If the two brothers were together, they could cause a short circuit powerful enough to cause a global power failure.
