Working on my character sheets now, if no one claims Roy Harper then I might bring him in as a non-Titans character. Like, he helps with the initial team-up at the beginning, but then his issues with Oliver Queen come to a head after the event, he abandons his Speedy persona, tells the Titans they are just the Junior Justice League and storms off. He then delves into drugs and alcohol, and becomes a rogue vigilante for a while going by the alias Arsenal. He'll join forces with the Titans during major story events, but otherwise he'll be fighting solo for some time until I decide what his fate will be. 

[@Martian], I know you had mentioned an interest in him, did you plan to bring him on as a third character at some point?
