[Western Crossover] The System Says I Must Keep My Secret Identity Under Wraps

A damn System bound me and gave me a secret identity, telling me to keep it well hidden.

Then I found out the secret identity was Batman (Young).

?????

And he’s a Batman who goes nuts whenever he runs into the Joker (?)

Huh? System, just kill me already! How am I supposed to face Batman like this?

They’re going to turn me into a trophy!!! I can already see myself in Batman’s files!!!

Damn System: Don’t let your identity slip. If it does, we all die.

Jason, battered and bloody after being beaten by the Joker: Just when I thought I was going to die, I heard someone call me Uncle?

Batman (Young), seeing Tony and Bruce: Grandpa!

Batman (Young), seeing Damian: Dad!

(Being revised...)

Theme: When Batman destroys the world and returns to the past.
