Simple, list your top ten favourite Teen Titans/Titans in order from favourite to least. See example below.

1) Arsenal/Red Arrow (Roy Harper)
2) Flash/Kid Flash (Wally West)
3) Hawk (Carter Hall)
4) Dove (Don Hall)
5) Donna Troy
6) Nightwing
7) Cyborg
8) Bumblebee
9) Guardian (Mal Duncan)
10) Aqualad (Jackson Hyde)

I keep a tally of the points (10 points for 1 spot 9 for second ect)

I did this a while back with the Legion of Super Heroes and it was fun, but man, I find it harder for the Titans.
