Odlaw is a character of the "Where's Waldo?" series. He is "mean, nasty, loathsome, and disgusting." His number of good deeds are few and all he cares about is getting his hands on Waldo's magic walking stick. His wardrobe includes a black and yellow striped shirt, black jeans, boots, dark glasses, yellow and black bobbled hat, and a slick moustache. Odlaw seems to be something of an evil twin to Waldo, and it is later confirmed by the revelation that he comes from Odlaw's Swamp in remote Maine, where hundreds of other Odlaws live, which is a parallel to the Land of Waldos. Odlaw can be really clumsy, so he always ends up getting hurt. His friends also tell him to frequently "Shut Up" and stop writing "Odlaw wuz here" on everything with which he comes in contact with. He is reportedly based on a young boy that illustrator Martin Handford met in Portland, Maine during a hunting trip.
Odlaw's name comes from "Waldo" spelled backwards. He first appeared in 1991 in the book Where's Waldo: The Magnificent Poster Book! where his role was like an "Anti-Waldo".
