Tyrone was the mentor of Bruce Banner in earth 1610 (ultimate universe) they worked on the super soldier formula. Leo was reliant on crutches to get around in life and subjected himself and others to his experiments. While everyone else died he survived and became the first hulk. He was soon thought dead but in truth escaped with his new far more powerful body [Ultimate Comics: Avengers #7]. He settled in south America where he took on the identity of Tyrone Cash and took over the local drug cartels and lived as king. Years later War Machine would seek to recruit him into the Avengers. He only agreed when they threatened to tell his wife and son what had really happened to him[Ultimate Comics: Avengers #8].
After he joined the Ultimates he fought Ghost rider and stole vital shield information before returning to south America. There he sold Shield owned super soldiers on the black market until Nick Fury found out and had Blade hypnotize him resulting in his return to his normal form. Unable to change back into his Hulk form he found it hard to keep control of his criminal enterprise [Avengers vs New Ultimates #2]. Tyrone later confessed who he was working for and the secrets of his super soldier formula before Nick Fury had him killed. [Avengers vs. New Ultimates #5]
