Kearson DeWitt

Kearson Dewitt was an ex-employee of Stark Industries.

Biography
Outside of Kearson working on the prototype to the arc reactor, Pepper Potts also revealed Kearson to be working on a secret project called PROTEAN until he was fired upon discovery of the project and the dangers it exhibited.

Kearson later began working with A.I.M. and forged an alliance with Russian General Valentin Shatalov and the Roxxon Energy Corporation when it became necessary to steal a copy of the J.A.R.V.I.S.' program to advance and run their projects. Later in a transmission Kearson DeWitt told Shatalov that there was a spy in his ranks and is displeased that he has brought S.H.I.E.L.D. to their front door.

Kearson, faced with losing everything used the copied J.A.R.V.I.S. program to create Ultimo and then merges his PROTEAN technology with it, allowing it to grow uncontrollably and quickly transforming it into an enormous metal Ultimo the size of a scyscraper. With the merge complete, Kearson has his men upgraded with PROTEAN implants and merges himself with Ultimo in an organic/machine hybrid.

On discovery War Machine acted as a distraction to prevent Ultimo moving to another location while Iron Man battled with the internals of the Kearson/Ultimo. Upon defeat of the Kearson/Ultimo hybrid, Iron Man learned that the effects on Kearson were irreversible.
