Does anyone think that Terra should be in the upcoming Teen Titans series? And if so, should she be a hero or villan?

No, I don't think she should be. Because in the final episode of Teen Titans, Terra said she was not going to cadastrar-se the Teen Titans and it would confuse the viewers even more.

Actually, I think she should. Because there was an episode where Beastboy found Terra. So I think they should try to make her remember who she is.

She should come back and a hero

Yes, villain
