It would be cool if MC started making Movies, Games, Series, Music and Comics from the Past World. Imagine Marvel Comics in DC World. In addition, the same Mortal Kombat exists in the DC Multiverse
MC should do a lot of preparation before Debuting as Batman: Build a Super Serum, Surveillance Drones and "Iron Knight" Suit (Batman + Iron Man), get Sources of Information in the GCPD and maybe even go to Smallville and meet Superman (and take the Blood Kryptonian đđđ)
This âbusiness attackâ focusing on him being young is too forced. All those allegations become moot if he assigns Alfred to be his proxy, his stand-in. Essentially, giving the role that Bruce would have, if he were of age, to Alfred.
Author, and MC can any Super Serum from Fiction? Then I would suggest "Black Light Virus" from Prototype World. Alex Mercer and James Heller used it to absorb Humans, view their Memories, and learn their Skills and Abilities. This Skill will definitely come in handy in DC World
All these problems are so far-fetched, with mc's technological level, it won't be difficult for him to kill all the people in the council of owls. Just send each one a drone with a cannon or a bomb and that's it. Even an assassin can do nothing if a bomb suddenly arrives at him.
