The Invasion Force are the main antagonists of the first major Extinctioners storyarc and are the ones responsible for the formation of the team itself - although in early depictions of the series the Invasion Force had strong elements of the trope known as "Humans are Bastards" the series creator has stated that he doubts all humans are universally "evil" (in fact they are officially shown to be diverse, since the series Androzons has benevolent humans and has crossed over with Extinctioners a few times).
