1. The End - Parts 1, 2 & 3 (4.11/4.12/4.13)
Without a shadow of a doubt, the best episode(s) of Teen Titans is the three-part season four finale (which was also originally intended to be the series finale), aptly titled The End.
Clocking in at a grand total of roughly an hour and fifteen minutes, this episode is effectively a TV film and a pretty amazing one at that. You see the Titans battling Trigon, one of the most powerful being in the DC universe, in a confrontation that has been teased since season one and built up to phenomenally all throughout season four.
From Cyborg, Beast Boy, and Starfire being forced to take on evil doppelgängers of themselves, to Robin fighting side-by-side with the recently-resurrected Slade, to the climax of Raven's triumphant defeat of her "father", this finale lived up to every bit of the hype.
Absolutely no time in this triple-length episode went to waste and as the tension built and built, you could truly feel the scope of all that was going on as it became clear that the fate of the very universe rested on the Titans' shoulders.
Season five was all well and good, great even. However, had this been the actual conclusion to Teen Titans, well, that would have been alright. It's that good.
