faild

This usually happens to your scheme for world domination once it is stopped by the blue bomber, Mega Man. Originates from a translation/localization error near the end of Mega Man 6 (1994) on the NES.

Mr. X: "My scheme for world domination has faild! But I still have enough power to destroy you!"
(Removes costume)
Dr. Wily: "Let the final battle begin!"
