Plue

Nikora, "The Canis Minor", or more commonly Plue, is a Celestial Spirit that has no obvious combat abilities and seems to be merely a comical character for his summoner Lucy Heartfilia. The character is pretty much the same from Hiro's previous work Groove Adventure Rave a.k.a Rave Master. He communicates through interpretive dance.

Appearance

Plue is a short, stout white creature (who is commonly referred to as a dog by Lucy Heartfilia) with bland eyes and a golden horn-like nose. He cannot speak besides saying Plue, but Natsu can understand what he is saying. He mostly communicates by using gestures and motions which makes Lucy think he's cute.

Magic and Abilities

Plue is relatively the same as he was in Rave Master. He loves sweets. He can only be summoned on Tuesdays, Wednesdays and Thursdays when Lucy makes her contract with him. But later, Plue could be summoned everyday. He serves as a cute pet for Lucy rather than a combat spirit.

Plue doesn't have any particular abilities, merely acting as a pet to Lucy.

Nikora's role in the story is much like a pet for Lucy. However, he was used to demonstrate how contracts are made to Natsu Dragneel. He also seemed to recognize Loke, during the Loke arc, which was possibly meant foreshadow Loke's revelation as a Celestial Spirit, or it may have meant nothing.
