Kelpie is a Ride Chaser used by Guardroids in Avalanche Yeti's Central White stage in Mega Man X8. They attack by trying to ram into the player from the front and back. Some will speed up and attempt to charge the player by popping a wheelie. They're also deployed by the Ravemanta during its encounter.
