Frazoid

Frazoid is the leader of The Idiot Clan and Matt's partner in crime. He's known for being active in Matt's comment section and is the gatekeeper of the cursed memes, as well as abstaining from uploading any videos unless he absolutely has to, being more active on both of Matt's main channels than on his own, much to the despair of some of his subscribers, but it's not like he cares about that.

Role on the channel
Frazoid is the mastermind who jump-started Matt's interest to start The McGuinness Experiment from as early as 2009, and has been Matt's go-to guy other than BansheePlant to run content ideas past. Frazoid has often given Matt advice about what sort of videos he should make and is the only person to watch the rough cut of Mad Matter videos before Matt's finished editing them, having final say in how certain things are depicted.

After the hiatus from TME in 2021, Matt made Frazoid the sole in-video collaborator on the channel for the first while of its existence after a falling out with people he'd collabed with on the original channel, deciding it was worth it to start with a clean slate on the new channel, excluding input from anyone other than people he really trusted and The Team.
