Now I am thinking about the day they need deniable heroes that can react to big things publicly, but not be connected to the League. Cue Alchemist making some kind of Golems/Androids to fill that niche.
It could be pretty interesting if Alchemist entered a Super Hero game to farm items needed to make his pseudo heroes realistic, maybe a game with Micro Transactions translating to things like a blueprint for transformations. So like in the Avengers game they are shutting down, you can buy the Grey Hulk skin, and he gets an item/blueprint that he could put on a golem/android and it would turn to a life like version of said skin.
Actually it would be funny if Alchemist was conned while in the Avengers Game, namely the characters acted wooden and lifeless, and almost robotic. But cause of their interactions with him they come back to life, only pretending to still be like that, and they use this to essentially use him like an Ark. Because their world is ending and they are aware of it, basically cause of said shutdown.
It would be a funny thing with Al having to approach the League and introduce him to a lot of refugees from a shutdown game, who tricked him into bringing them back to DC Young Justice world. Though Batman while upset would likely see a use for them, namely as a resource to call on when things are dire. Seeing as they likely had Hank Pym shrink the Helicarrier to smuggle it into Alchemist's realm, well it would likely appeal to Bruce having access to the plans for a mobile command center like that.
