Re: Spiderman vs...
Old bats is by far the smartest.
I believe in the old DC heroes he ended up with a 12 Intelligence. From what I remember about the system, every point above 2 [human average] is a doubling. So, in HERO fashion, this would leave Batty with an INT of what, 60? I certainly wouldn't give Spidey that. Sheesh, Reed Richards may not even get that.
Of course DC vs. Marvel is a silly argument in terms of power classes, DC is by far more powerful.
As a side note, I remember Aquaman having a 13 INT and Supes coming in with a 14. Oh well, I guess they had to give Aquaman something...
