King Nerd
King Nerd is a fictional comic book character who appeared in stories published by ID Comics. He first appeared in The Liberty Guild #87.
Larry Nedrowski was a fan of ID comics on 'our' Earth. But, when he discovered a magic typewriter, he was able to transport himself inside his beloved comics. In the IDverse, 'King Nerd' (as he christened himself) was able to manipulate reality with his typewriter, and used his powers to wreak havoc across Century City, including turning Sprint to stone and removing Morrigan's powers. Eventually, the Guild outwitted Nerd, who was sent back to our world. But he would appear many more times in various ID comics, appearing with his typewriter and causing chaos, only to be defeated by trickery.
Lately, King Nerd has become a sort of editorial device, a way for the ID writers and editors to poke fun at themselves and the industry. He will often appear in comics to make jabs at the very book he's in, or to point out plot-holes.
In Forumopolis #185, Carter Boe gave King Nerd the nickname "Duke of Doofus".
