Technically shouldn't you hate the JL since they're the one's who made the Hellbat? I don't see why so many people have a problem with this for 1 for all we know the fight could be short with Darkseid winning. Secondly even if Batman does win, who cares? He's a fictional character if the writers make it so the suit the JL made for him is capable of defeating someone as strong as Darkseid then that's what is. I wouldn't say "Superman bench pressing the weight of the Earth for 5 days straight is stupid" because in this fictional universe that is what the writers have shown he can do. And I don't see how Batman being made more powerful makes him a worse character if that's the case you should start hating every comic book character since they're all stronger than they were when the were 1st created. It's funny how Batman is the only who is a God and OP when he gets stronger but not with others. In JL 35 Lex said he has tech that can kill an army of Kryptonians in his lab. Lex who struggles with just 1 Kryptonian allegedly has tech to kill an army of them, that makes sense. Lex has become OP and Godlike too but I've yet to see anyone complain about it.
I hate how Batman is held to a harsher standard than other characters.
