The best episodes of Teen Titans was often when a villain would put a Titan into an interesting situation that they had to deal with. Such was the case with Warp, a Time Traveler who tried to steal an item. Starfire stopped him, but not before getting flung into the future, a very dystopian future mind you.
Warp is arrogant, to the fact that he felt he couldn't be beaten because he knew what the future held. What he soon learned though was that the future is always in flux, and events can be interpreted many ways. An accident led to him being de-aged, what happened after that...only time could tell.
