Leonard Williams was a professor at Cambridge University who worked with a young Bruce Banner to recreate the Super-Soldier Serum, becoming a mentor to him. Williams disappears in an unexplained occurrence in which several people are killed, and comes to be considered a missing person.[2]
Unbeknownst to the public, Williams survived, became the first Hulk, and assumed the identity of Tyrone Cash, killing numerous people throughout Africa and Asia before becoming a gangster in South America. During this time, S.H.I.E.L.D. monitors him and eventually recruits him into the Ultimates.[1][3]
S.H.I.E.L.D. later discovers that Cash has been selling Super-Soldiers on the black market. Blade defeats and depowers him before bringing him to the Helicarrier, where Nick Fury kills him.[4][5]
Powers and abilities
Using a pill that contains a perfected version of his Hulk Serum, Tyrone Cash has immense strength, stamina, durability, and speed, as well as regenerative capabilities, which are similar to those from the Hulk. Cash also has shown to be a very skilled scientist.
