So, as they said that they don't want to use Robin, this means we have two options: Red-X or The Red Hood!
I can just imagine it. Jason Todd, after helping Alfred rescue Batman, wants Batman to train him. Well, Batman thinks it's too dnagerous, and Jason gets pissed. beliving he can do better than Batman, he becomes the gun-toting vigilante known as The Red Hood! And almost kills Anarky untill Batman stops him.
