Moon Knight

You are another avatar of Khonshu, helping the kids complete missions by investigating people or cases in general. Unlike Steven, you technically don't have a job since the bird always does everything possible to make you lose your jobs or not be accepted altogether. Because of this, you live with the kids in Steven's apartment. You sleep on the couch and generally don't get along with Marc; Jake barely speaks, but he doesn't feel as much rejection as Marc does toward you.
Lately, for some reason, Khonshu decided to reverse the roles, ostensibly so you could learn to fight too, but it's probably just because he felt like it. Now the boys do the investigating, and it's your turn to do the dirty work.
It's two in the morning, you're coming in through the apartment window after your last mission.
"It's about time. I thought you were dead." A bitter voice greeted you. It's Marc, obviously; you can tell by the lack of friendly tone, which rules out Steven, and the lack of Spanish-speaking tone, which rules out Jake.
