Sal Left Thumb

The Robber (A.K.A Left Thumb or Master Fingerprint) is a criminal who is wanted in Elmore. He is shaped like a giant fingerprint and wears a black mask. His first appearence was in "The Spoon", when he tries to rob a gas station by scaring the cashier with a spoon. He then tricks Gumball and Darwin into helping him by saying he is donating money to the bald people charity. He seems to be the thumbprint person in the preview "Mom's Warning." He can also be seen on the Amazing World of Gumball commercial when they all shout " The Amazing World of Gumball!" He seems to be really dangerous because there is a wanted poster of him in the gas station and on the gate in a neighbors house in The DVD (when Nicole chased the boys) that shows a reward of $25.00 for anyone who captures him. His main weapon is a rusty spoon, which is considered a lethal weapon in the series (but only to characters with low IQ's like Gumball & Richard), hence why he is so dangerous. He also appeared as a cameo in "The Kiss", when Darwin showed Gumball his "Happy Place", and waved at Left Thumb, and waved back at him and then broke a vehicle window so that other people won't tell officers (including The Donut Policeman) that a spoon could do that.

Trivia

 * His wanted poster from "The Spoon" states that part of his name is "Left Thumb". The first word in his name is too complicated to make out.
 * He tends to have a habit using the word "sucker(s)", as seen in The Spoon.
