I am Red X. I'm Nightwing from a dark, alternate future where Starfire disappeared into a time-generated portal and didn't reappear until many years later. I traveled back in time, stole the Red X suit from my younger self--Robin--and did what I could to change the future into a better one. Even if that means battling with everything I have against my former teammates, the Teen Titans. Also, I very much regretted never dating Starfire. When I get back to the future, I'm marrying her.
