Plot hole: When the raptors bring down Beast Boy in his Tyrannosaurus form, he escapes the batch lying atop of him by turning into a dragonfly. When he does so, the heap of dinosaur bodies does not sag down at all, and to fill out the gaps, a whole lot of additional raptors appear in his stead from God-knows-where.
Continuity mistake: When Gnarrk attacks Dr. Light's amplification machine, the wrench Cyborg threw at him has suddenly grown in length. At first his fist encloses the whole grip, but a minute later it is long enough to be used as a club.
Chosen answer: It is located in California, as shown in "Teen Titans: Trouble in Tokyo". Possibly San Francisco as seen in the comics.
