Actually I’ve never answered this questions before, and this is a really tough questions actually.
My favorite from the main five titans would definitely be Raven, she’s always been my favorite since I was a kid first watching the series.
But my favorite supporting character would have to be Jinx. She’s barely in like 10 episodes but gosh I love her so much.
So basically my favorite character is Raven closely followed by Jinx and everyone else :p
