I was wondering why Superman has never offered to give Batman some sort of Kryptonian cloth. Maybe they have done this, but I've never read it, or they just didn't want to make Batman more unbeatable. I think it would make sense that Batman would want this tech, it would make him less vulnerable to super powered attacks, and it would weigh less than his previous suit. It would also fit perfectly with his paranoid perception that the Justice League could possibly become evil or just mind controlled to do bad things.
Does anyone think Batman should acquire some Kryptonian tech to make his suit better? Or does he just not need it?
If he's going to fight amongst the Justice League, I think he should.
