GregF is an incredibly powerful being, said to be of the same species as The Users. He helped create the BIONICLE universe, which later became fused with the BZPB Multiverse. He is known to be good friends with Iron Man, and helps him in combat very rarely. In fact, he has only appeared three times, one for every year BZPB has been running. In his first appearance, he was hit by an anvil fired by the Matoran in a Black Suit. He threw the MiaBS into a wall, but Muta threw the MiaBS into him. He was then used as a club to bash Muta. Later, he interrupted a speech by MakutaKlak.
