My true final level I always imagined an epic scene in which I have to defeat a major boss-level professor at my college in a fist-fight, philosophical and intellectual discussion while at the same time breaking clay pots with my legs. It would end in some sort of homage to History's Strongest Diciple Kenichi in a manner of speaking.
The kind of thing that would take place on top of the school's tower and decend into the courtyard depending on who gets thrown where, and a chance of weapons thrown in or guest star appearances by Jackie Chan, Weird Al, Bill Clinton, and the Harlem Globetrotters (for no apparent reason). It would end with two final punches thrown and caught and a whisper of a final question, the answer is accepted and a torn, battered degree bathed in light and awesome would be presented as I stand with my fist raised to the sun.
That's about it for college life, next onto the real world (if I can think of it, I will post it as a separate battle.)
