The Main Event is the highest achievement for a character in the FPL. Characters begin in the Undercards, facing other beginning characters. Once they've achieved 5 victories, they proceed to the Elimination Rounds. After 5 victories there, they go into the queue for the Main Event.
There have been... hell, I dunno, A LOT of Main Event winners since the FPL came into being in 1998. Or was it '99? Main Events used to be numbered, with accompanying commentary.
The first Main Event was between CBUB commentators Pat and Jay. I think.
