How to tell you haven’t read ANY Batman comic without telling you haven’t read any Batman comic…
No, Trump is not Batman nor Nightwing nor Robin. He’s too craven, stupid, corrupt, unhealthy, and selfish for it. He’s also not the Riddler as Riddler actually is a genius (not as much as Riddler thinks he is, but still not stupid at all). He’s also not the Joker as Joker is also smart and charismatic and eloquent all things considered. He’s also not Mr. Freeze as Freeze actually loves his wife tremendously. He’s also not Bane as, again, Bane is smart and competent.
Nor is he Luthor as Luthor is a certified Genius. He’s not Darkseid as Darkseid actually is threatening. He’s not Sinestro as Sinestro actually has good intentions all things considered. He’s not Grodd as Grodd, again, is a Genius.
He’s not Superboy Prime, as Prime is actually powerful and threatening. He’s not the Batman who Laughs, as that thing has both Batman AND Joker’s cunning.
No, Trump is more like… well, his own thing. I don’t think there is ANY DC or Marvel Supervillain who is at the same time craven, stupid, corrupt, unhealthy, uncharismatic, lazy, and selfish while still succeeding through sheer, dumb luck.
