Gunsmoke

Gunsmoke was Freddie's bodyguard in the iCarly episode iSam's Mom. Mrs. Benson hired Gunsmoke to protect Freddie after Freddie got footage of The Shadow Hammer (who has been known to never have been caught on camera) robbing the Groovy Smoothie.

Gunsmoke has participated in three wars (none of which were named) and has a hole in his leg that has nothing to do with any of the wars. Not much is known about Gunsmoke, but it is shown that despite his violent nature, which includes watching gory movies and violently stopping others from having physical contact with his clients, he is shown to have a somewhat soft side. Gunsmoke enjoys the show "Full House" and has expressed a liking for snow cones.

He takes his job very seriously. When he was hired to protect Freddie, he attacked Spencer several times over a trivial matters, explaining that he wouldn't allow anyone to lay a hand on Freddie.
