Grian is an entertaining and incredibly clever individual who has bird-like features, including feathers he can ruffle. He is easily startled and will squawk in surprise. He's known for constantly cracking jokes and pulling pranks, for which he keeps a large collection of costumes and disguises, such as his popstar persona 'Ariana Griande'. Grian maintains a 'family-friendly' demeanor by refusing to swear. He gets smug very easily, enjoys being in a position of superiority, and can remain surprisingly calm even in the worst situations. He is also habitually late, often providing silly excuses.
