The Liberators were introduced in "Ultimates 2", formed by Loki (under the alias of Norwegian scientist "Gunnar Golman") and featured recruits of superpowered villains that invaded the United States of America. They had support, at least tacitly, from the governments of China (the Abomination/Chang Lam and the Crimson Dynamo), France (the Schizoid Man), Iran (the Colonel), North Korea (Hurricane), Syria (the Swarm, later the Red Wasp), and Russia (Perun). Additional allies included Natasha Romanoff/the Black Widow, the former Ant-Man Hank Pym and his Ultron/Vision II sentries. They were defeated by all of America's heroes, with only Perun surrendering to S.H.I.E.L.D. and being held in the Triskelion and Loki being held by Odin for inciting a world war.
