[Comprehensive British and American] the System Asked Me to Put on My Vest and Don't Take It Off

I was bound by the dog system, and it gave me a vest to wear well. Then I found out that the vest is Batman (small) ? ? ? ? ? Or a Batman who gets crazy when he meets the Joker(?) Huh? System, kill me! How can I face Batman with you like this? I will be made into a watch! ! ! I can already see me on Batman's docket! ! ! Dog system: Don't lose your horse, otherwise everyone will die together. Jason, who was beaten all over by the clown: When I thought I was going to die, I heard someone calling me uncle? Batman (young) saw Tony and Bruce: Grandpa! Batman (young) sees Damian: Dad! (Modification in progress...) Concept: When Batman destroys the world, go back to the past.
