Mieu

Mieu is a young cheagle from Tales of the Abyss. Cheagles, considered holy by the Order of Lorelei, normally live in herds in the forest, but fate will bring him to join Luke and the others on their adventure. The Sorcerer’s Ring that he wears around his stomach allows him to use human speech, and he can use the ring’s fonic power to breathe fire. As the game progresses, Mieu also gains the ability to tackle objects, along with a stronger fire breathing ability and even the ability to fly should the player fulfill certain objectives.

Story
Mieu was the cause of the fire that burned down the forest to the north of the Cheagle Woods, and angering the ligers that had lived there. In return, they moved into the Cheagle Woods and forced the cheagles to supply them with food, which the cheagles then stole from the people on Engeve. Fon Master Ion, wanting to help the sacred beasts of the Order of Lorelei, agreed to go see the Liger Queen, in which the elder of the cheagles had Mieu follow Luke and the party as a translator to speak with the Liger Queen. However, the Liger Queen refused to cooperate and attacked them, which led to it's demise at the hands of Jade Curtiss when he arrived on the scene. After that, the Cheagle Elder exiles Mieu from the tribe to serve Luke for one cycle on the seasons. Although at the start of the journey, Luke didn't get along with Mieu and treated him horribly, up to the extent of giving him the name, 'Thing'. However, Mieu still believed in Luke and did whatever he could to help Luke and was also the only one who stayed back willingly with Luke after the destruction of Akzeriuth and most of the party returned to the surface with Asch. Mieu also calls Luke 'Master' throughout the game. Eventually, Luke warms up to Mieu and considers Mieu a valuable ally and friend. In terms of friendship with the other party members, Mieu would do anything to protect them and considers all of them his trusted, valuable friends.
