I choose Miss Martian because she was such a weird fit and unnecessary addition on the Titans and Jonn is already on the league so I thought she should take his old position in the government.
Sarah Charles was a choice I decided so she can get more exposure. Her at S.T.A.R labs really isn't much especially since that corporation went into limbo since the new 52.
Damage was really close to Roy so I just added him lol.
