Changkey (チャンキー Chankī?), localized as Tackle Fire in some English sources, is a fire enemy from the original Mega Man series, usually spawned by various other enemies. In Mega Man 2 and Mega Man: Dr. Wily's Revenge an enemy called Changkey Maker creates Changkeys. It appears in Fire Man's stage from Mega Man, Mega Man: Dr. Wily's Revenge and the first part of the Wily Tower in Mega Man: The Wily Wars. In Mega Man: Dr. Wily's Revenge, they are invincible and just appear falling into lava. They also appear in Mega Man 10 in Solar Man's stage, Wily Castle stage 4 and Special Stage 1, where four of them fly in parabolic arcs from one turret to another and back.
