I actually want to discuss to Jason Todd is Red X topic. So many people theorize and many have their reasons why he is not.

I am one of the many who believe Red X is Jason Todd and here is why. Red X always took a great interest in Robin AKA Dick Grayson. He was able to break into the tower and leave unnoticed. Training from Batman can explain.

He also had a similar attitude like the witty comments about Dick. Although, beast boy AKA Garfield Logan, had a theory that it was him, but that was one out of many. He still seems to have a strong belief that he is right. Robin probably refuses to believe him because he is still getting over the fact he's dead.

In episode X, he saved Robin and the Titans showing that he cares the same thing doesn't happen to Dick. He fought with similar moves as Dick. Almost the same. They both, Dick and Jason, were trained by batman. Plus, Red X is similar to Red Hood. They are almost the same attitude.

This chapter was sorta a head cannon but I personally think he's Jason Todd.
