All we need is a Red Hood and a big bad alien. :P

I mean Rose fills the Red Hood spot pretty well. Since the original Team was Jason, Roy and Koro. We have Rose and Thea, just need a 'Kori'. Based on gender dynamics it should be a male haha. 

Kryptonian? Martian? Daxamite? Tamaraean? So many options.
