The Runaway Guys are a trio of popular, collaborating LPers who sometimes have a fourth player with them.
The members are Chuggaaconroy, NintendoCapriSun, and ProtonjonSA. The ingame relationship between each member changes with each game they Let's Play. For Example: In games where they can play competitively like New Super Mario Bros. Wii, ProtonJon and Chuggaaconroy will constantly try to kill one another, and in the "Mario Party" games, all members may try and team up against the AI player if they are being beat by it.
