10 Smartest DC Characters
1. Lex Luthor
No matter what the universe throws at Lex Luthor, he always has an answer. A genius, as well as an expert engineer, Lex seems to adapt to any situation with ease.
His mind is constantly on the go, whether that be plotting the fall of Superman or planning his next attack against mankind, and even though there is little doubt he is an utterly ruthless villain, his ability to be such with little to no repercussions, most of the time, always leaves the reader with a certain grudging respect for him.
He is a master of all science, which is impressive enough in itself, as well as a self-made billionaire and, for a long time, the darling of Metropolis. Hell, he even managed to get the big seat in the White House for a while.
But what is most impressive about Luthor is that he manages to achieve all of this while being a simple human being. There is nothing meta about him, he has no powers to speak of, other than his dizzying intelligence, and is nothing more than a man with a brain the size of a planet.
This alone is enough to make him the smartest character to ever grace DC.
