Kervo

Kervo is a nine year old human and member of the Guardians. It is unknown how or why he joined. He was raised by the Okorans hence his name.

Guardian Era
A few days after defeating Thundra, Kervo and the other Guardians returned to Plit, landing not too far from, but out of sight of, Castle Black. Shortly after the Guardians left the ship, Black Toadette appeared and kidnapped Stardown.
