First version of the character outside the comics, and currently the only.
In the ComicsEdit
There really was a Nazi officer named Kleiser. The Chitauri who took the name absorbed and devoured this man.
He and the other Chitauri spent the years between World War II and Captain America's return secretly influencing human affairs to prepare for the invasion.
His Chitauri infiltrated S.H.I.E.L.D. to lure the Ultimates, renamed the Avengers for the videos, to Micronesia where he set off a nuclear device to kill them. Iron Man's force field and Thor's teleportation saved them, adapted into the destruction of the ship in the second film, though thousands of S.H.I.E.L.D. personnel were killed.
Soon after, he and the other remaining Chitauri infiltrated the Triskelion, kidnapped Wasp, and took her to Area 51. The Ultimates arrived while Kleiser and Captain America fought. Kleiser was defeated when Captain America told Hulk that he had been "all over Betty" and the green giant ate him.
While Bruce Banner was captured, S.H.I.E.L.D. studied his excretions fearing that Kleiser may have returned.
