In Rave:
Plue is the bearer of the Rave Stone, as well as a companion to the Rave Warriors. Plue is a stout, white creature, reminiscent of a snowman, that only comes up to three feet in height. He has a rounded head that is a tad too big for his body, with a horn for a nose that strongly resembles a carrot. Additionally, Plue also has some resemblance to a canine with his monosyllabic pattern of speech, and occasional tendency to walk on all fours.
When he is hungry, Plue's nose would deflate. Similarly, when overheated, his whole body wrinkles, and eventually decompresses entirely. Despite its tendency to shrivel under several circumstances, Plue's nose is incredibly hard, enough to pierce through objects of varying hardness, from human flesh to Dark Brings.
Plue has strong affections for lollipops. The only word he is capable of saying is "puun", which Griffon Kato seems to be able to understand. He gets easily sidetracked by trivial things, often chasing after peculiar insects and butterflies, or falling asleep at random moments. Despite his small size and overall fragility, Plue does not back away from a fight. He would aid in battle by throwing stones, or giving his enemies lollipops. He is also extremely loyal to his friends, to the point where he willingly sacrifices himself to protect Shiba Roses from the Overdrive. Plue, however, cries very easily.
In Fairy Tail:
Plue is a Silver Key Celestial Spirit with no actual combat abilities, stated to be usually kept as a pet for less powerful Mages, including Lucy herself as his owner. His key was sold for 20.000 Jewels. Because he is not made for combat, Plue serves as a cute companion instead. He is very obedient and ready to help Lucy whenever she needs his help. Along with that, he enjoys sweets and shares a close friendship with Happy and is often seen teasing Lucy and Loke along with him. He is also very apologetic, as he immediately apologized to his owner after harming her under the influence of Sherry's Magic.
