Chuck Norris once played a Generation V Pokemon game and caught a Raichu. The Raichu is now defiant enough to knock out an Excadrill with Bolt Strike. How is this defiant? Excadrill's types are Ground [has immunity to Electric-type moves] and Steel [has resistance to Electric-type moves], Raichu normally cannot learn Bolt Strike, and Raichu don't normally appear in Pokemon Black and White in the first place!
