I liked the idea of Dane being a Nephilim in contrast to Raven who is a Cambion.

I realized that the Titans behind the students has some sort of a relation or connection to each of the Titans. Dane being Raven's mentee and them being potentially mythical counterparts with the latter showing angelic wings, Flash and Bolt being Speedster, Victor being a Cyborg in contrast to Stich who is an animated doll probably with a soul (she is like a mystical '' andriod'' or some sorts, Nightwing and Chupacabra has already been explained and Matt Price being an amnesiac in contrast with Donna who used to have all sorts of memories.
Both Beast Boy and Toby are comedic shapeshifters and I have no clue for both Starfire and Winter maybe opposite elements (Fire and Ice). Red X is in front of Roy Harper so maybe Roy used to be Red X because IIRC the previous Red X while in incognito was wearing both a cap and sunglasses.
