Matthew is a Human and an enemy of the Solar Opposites. He told Korvo that he was not allowed to wear Christmas sweaters since he doesn't know about Christmas. Korvo got mad and shot him with a Sci-fi Holiday Cannon. In revenge, he teamed up with Ms. Frankie and Roland to frame the Solar Opposites for torturing Peter the pig.
He was accidentally impaled by Ms. Frankie with her Wolverine claws.
