A boss at the end of the game who looks really weak and let's you think 'woohoo that was easy', but still somehow it took lots of unnecessary lost lives so you have only one or two lives left, it let's you think that you finished the game really easy, but then it suddenly gets a big upgrade, and is like ten times better than before, so you are like OMG, he's fucking ΓΌber, after which he finishes you off with one of his first attacks.
Endboss of ANY good, or Zelda game.
