Maxwell Markham is a professional wrestler who competed using the nom de guerre of the Grizzly. His violent actions brought him to the attention of J. Jonah Jameson whose articles got Maxwell expelled from wrestling. Ten years later, he met with the Jackal who gave him a grizzly bear suit and an exoskeleton harness that amplified his strength and durability. He used this harness to attack the Daily Bugle in an attempt to get revenge against Jameson for ruining his wrestling career, but Spider-Man defeated him.
