Many Transformers stories -- and many stories associated with other action-oriented brands -- have a dramatic climax which takes the form of a really big fight at the end (often abbreviated as RBFATE). During the really big fight at the end, nearly all the characters who have appeared in the story participate in a grand melee. In almost all cases, the good guys get the upper hand (often by destroying the bad guys' EI/AD) and the bad guys retreat. Sometimes, at that point, somebody makes a bad joke.
