Mogg comes from a wealthy family. He was a big-shot high school athlete, the captain of the track team and the coolest guy in his social circle. In 1996, he ran for class president. At the time, Megg was dating Werewolf Jones and it's shown that he was jealous of his friends's relationship.[5] After they broke up, Mogg started dating her.[6] Nowadays he's an unemployed loser approaching his 30's who's done nothing of value with his life.

While being accosted by the cops over a robbery at a local deli, Mogg (who was responsible for the crime along with Megg) tries to incriminate Owl (who wasn't involved in any way) as the culprit. Mogg was already in the clear, so he does this for no reason other than finding it funny to besmirch Owl's name while lying to the cops.[7] He either doesn't realize or doesn't care that Owl getting charged with a serious felony would effectively leave him and Megg homeless and without most of their monthly income.
