Chitauri

The Chitauri planted false information through the compromised Psi-Division that led S.H.I.E.L.D. and the [[Ultimates]] into a trap on a small [[Micronesia]]n island; due to the combined efforts of [[Iron Man (Ultimate Marvel character)|Iron Man]] and [[Thor (Ultimate Marvel)|Thor]], the Ultimates, [[Nick Fury (Ultimate Marvel character)|Nick Fury]], and a handful of S.H.I.E.L.D. soldiers survived, but thousands of S.H.I.E.L.D. soldiers were killed and dozens of [[Helicarrier]]s were destroyed.

The Chitauri then counterattacked by infiltrating the Triskelion and capturing [[Wasp (character)#Ultimate Marvel|Wasp]]. The Chitauri leader (known only by his former [[Nazi]] identity Herr Kleiser) took the Wasp to a hidden Chitauri base in Arizona. However, their location was given away when a fleet of damaged Chitauri starships entered Earth's atmosphere, claiming that they were fleeing major defeats across the galaxy by their intergalactic enemies and that the remainder of their forces are forced to the [[Solar System]]. Disregarding Kleiser's long efforts, the Chitauri ordered him to destroy Earth and the Solar System with a doomsday bomb as part of a scorched-earth policy and retreat to the "lower fourth-dimension". The Ultimates and all available S.H.I.E.L.D. and military forces immediately converged on the alien fleet.
