Gaardus

Gaardus was a former Fe-Matoran who was transformed into a monster.

Early Life
Gaardus was originally a Fe-Matoran on the Island of Nynrah. He was apparently happy and content there. However, the Nynrah Ghosts took him away and experimented on him so their island could be protected. They accidentally transformed him into a winged Rahi-like monster. He hunted them all down and killed them. It is unknown what happened to him after that, however he apparently visited the Red Star, which he claims has bad hunting.

Spherus Magna
He later escaped out of the Great Spirit Robot by blending in with Rahi. He went on hunting, and eventually found Tren Krom, who, before his death, planted the image of the Red Star in his mind. He then scavenged from what was left. Kopaka later froze his wings and asked him what he was, and Gaardus told his story. He soon agreed to take them to the Red Star again, and encountered the Purple and Black Entities, who recognized him.

Powers and Abilities
Ever since his transformation, Gaardus gained the ability of flight with wings. As a hunter, he can return to places he has been before.
