Loki's escape presented a fresh problem for the survivors of the attack. Romanoff attended to her old partner while others counted their losses, but she was quick to join them once they had resolved to go on the offensive.

Loki's army, a horde of Chitauri warriors, came pouring through and Romanoff found herself again battling in close quarters, this time against an alien foe bent on world domination.
