3. Batman (Bruce Wayne)
I mean, duuuuuhhhhhhh. No, he's not in the top two; those spots are reserved for people whose brilliance could be used to remake the universe if they so choose. But Batman is as smart as you can possibly be without reaching that level.
Bruce Wayne spent his entire life and a lot of his rich-boy money traveling the globe learning as much as he could about everything. Science, philosophy, art, martial arts, everything you need to learn to be a Batman, he learned it.
I mean, the dude is the world's greatest detective, his acuity is spot on, and his mental abilities are unparalleled. I mean, he's Batman.
He's a powerless man in Zorro cosplay who stands toe-to-toe with the most powerful men and women on the face of the Earth. And we all believe it makes sense, because he's friggin' Batman, and he's smart as all hell.
