The greatest minds of the marvel universe have NEVER been able to replicate the super soldier serum, and you expect batman to do so with a DNA scan?
Please, tell me more about how Batman is a better scientist than Reed Richards and Dr. Doom.
Ignoring Marvel, Batman isn't even on Professor Ivo or T.O. Morrow's level. I have no idea why DC sometimes insists he's the second smartest person on the planet where he lacks most of the feats associated with other super geniuses. It's like they forget about Rip Hunter, Will Magnus, etc.
