a mommy guard
A mom who fights for her son like he's the last hope of humanity. The kid gets powers and starts acting like a boss while his mom yells and calls the cops. The kid is a total failure who plays a video game all day and still thinks he's the best.
My son got beat up? I'm calling the cops and getting my dog ready to attack you!
He's not even cool! He plays CODMOW 2 and thinks he's the best in the world.
You're just a loser who plays a video game and thinks he's cool.
