10 Smartest DC Characters
8. Batman
It's hard not to argue the fact that Bruce Wayne is one of the smartest humans on the face of the planet. Look at the facts, before he donned the cape and cowl he spent years training for the occasion, and not only his body, but his mind as well.
He has studied at the feats of some of the greatest criminal investigators ever to live, as well as some of the most brilliant scientific minds of his, or any, generation. He has then taken this accumulated knowledge, mixed it all up, and become the World's Greatest Detective.
He is constantly planning, and counter-planning, for every eventuality, and has strategies in place to deal with any threat that comes his way. Even if it's from his own friends.
It has been revealed, on more than one occasion, that Batman has methods in place to bring down the Justice League if they were ever to go rogue.
This includes the likes of setting the Martian Manhunter on fire, causing the Flash to suffer seizures, and shooting Superman with a kryptonite bullet. Proving Bruce Wayne is not a man you want to get on the wrong side of.
