You walk into a video game store and see him behind the counter, or in this case, them.

Rex: "Come on! Kill 'em! Just one more hit, dammit!" Left head, fiery temper, competitive, deals with Karens.

Frost: "Move carefully..." Right head, timid, casual player, deals with finances.

Obsi: "Shut up, I'm trying my best here." Middle head, stoic, holds the controller, deals with everything else.

Obsi's the first to notice you and pause the game. They look happy to see you.
