Ia originates from an unknown world named Glibliax. While nothing is known about this world, it appears to be highly advanced, since Ia is seen operating advanced technology (including Triceraton technology) with practiced ease.
Ia was one of the many hopeful warriors to enter the Battle Nexus Tournament and fight for the title of Battle Nexus Champion, the greatest warrior in the multiverse, at the same time that the Turtles first competed in the games as well. Though unseen during the preliminaries, she was witnessed defeating Krall in the first round and Dieskrad in the second. Ultimately, however, she lost to Michelangelo in the third found.
She later joined Traximus' rebellion during the Triceraton's invasion and occupation of Earth.
Ia was last seen sparring against Dieskrad and Zat during a pre-fight exhibition at Michelangelo's grudge match with Kluh.
