Lists of characters

RMA features a large and diverse cast of characters, though the only one of note goes by the name of Grug. Grug is a short white caveman dressed in brown cloth and is the original inhabitant of the island of RMA. Grug is best known for the fact that, no matter time of day it may be, it is always his moment. This has led to members of RMA coining the phrase "Grug Moment," an expression with loose meaning that is generally used in reference to an ongoing or recent event seen as positive or exceptional. Grug's name is also used as an adjective, specifically in the phrases "Grug Morning" and "Grug Night," which are for all intents and purposes synonymous with "good morning" and "good night" respectively.

Grug has on occasion been seen sporting sunglasses and a joint. This image of the character is used to signify when something is seen as a "Thug Moment."
