Upon first glance, AAARRRGGHH!!! appears to be a hulking brute, but in reality, he's a gentle giant with a limited choice of words. He often speaks in simple sentences such as: Jim Good. Once a feared lieutenant for Gunmar's army, AAARRRGGHH!!! has since renounced his heinous ways and has joined the good Trolls. A reformed fighter, AAARRRGGHH!!! has adopted a zen-like attitude for pacifism, avoiding conflict. As threats grow and stakes rise, will AAARRRGGHH!!! remain a pacifist for long?
AAARRRGGHH!!! is a huge Troll with rock-like gray skin, green eyes, and a dark green beard and hair on his shoulders and chest. He has four short horns and a large black nose, and patterns on his arms, knees, and chest. When AAARRRGGHH!! is overcome with anger or he is in an uncontrollable rage, the patterns on his skin light up with a green magic, similar to the krubera’s blue patterns, and his eyes turn completely black with glowing green pupils.
Toby is a close friend of AAARRRGGGHH!!!, often referring to each other as each others "Wingman". Toby and AAARRRGGHH became friends almost instantly. When AAARRRGGHH decided he would leave with the Krubera Tribe, Toby seemed very devastated and that was enough to convince AAARRRGGHH to stay.
AAARRRGGHH!!! and Blinky are close friends. They are rarely seen apart. When AARRRGGHH!!! became good, Blinky didn't really trust him at first but over time Blinky and AAARRRGGHH!!! became close friends. When AAARRRGGHH!!! was turned to stone Blinky was shown to be incredibly devastated and kept his remains in the library and was overjoyed when AAARRRGGHH!!! was revived.
AAARRRGGGHH!!! and Jim are often seen casually sparing as part of Blinky training Jim. Jim and AAARRRGGGHH!!! are also friends. When Jim was turned into half troll, AAARRRGGGHH!!! didn't like Jim being half-troll, but then he realized that Jim became just as wild and strong as him and accepted it.
Claire and AAARRRGGHH!! do not interact as much as most of the other characters, but they do have a mutual respect for each other, and later in the series AAARRRGGHH!! gives Claire a wide berth, fearing her tool of Morgana
