Worriz

Worriz is a wolf-based robot and one of the Hero Factory's despised villains next to the recently reactivated Vahki.

Early life
Worriz was one of the six animal robots that were created by the Hero Factory as prototype models for the animal-based armor used by the Heroes in the mission to the jungle planet Quatros. Worriz, along with the other animal robots, were never intended to be Heroes and were built with cores made from a substance known as CHI rather than Quaza.

Worriz later learned that he and the other animal robots were never made to fill the duty of the Heroes, which lead to Worriz trying to convince the other animal robots to attempt to overthrow Hero Factory. The other animal robots disagreed to this and warned the Hero Factory of Worriz's plot to overthrow the Hero Factory. Worriz attempted his takeover of the Hero Factory without the other animal robots and without knowing that the others had warned the Hero Factory of his plan. Worriz soon realized that the Hero Factory forces were prepared to stop him and drove away in a stolen Drop Ship, leaving the other animal robots to be deactivated at Hero Factory while he fled to a nearby planet within the solar system.

Later life
Worriz remained hidden on a dark and desolate planet within the solar system of the Hero Factory Universe up until about three months after the Brain attack in Makuhero City. Worriz recruited proxies such as Black Phantom and Dark Maker to do his bidding without revealing his existence to the Hero Factory. Before planning to return to the Hero Factory, Worriz decided to give himself more power by creating CHI through the planet's rivers.
