Stalker (Helldivers 2)

"'A side effect of Terminid gene-splicing research, Stalkers can camouflage themselves in their fascist lies almost to the point of invisibility, but ultimately nothing can hide from the cleansing light of Freedom.'"

The Stalker is a large-sized Terminid that comes from a Stalker Lair. They appear to be mutated Hunters with camouflage capabilities and enhanced strength. There are reports that this strain of Terminid appeared during the First Galactic War, but there is no evidence that they had camoflauge capabilities before.

Theories claim that this camouflage ability was the result of Super Earth tampering with Terminid DNA to make them produce more E-710 or Super Earth had some kind of secret Terminid weaponization program in an attempt to create an army of controllable Terminid Stalkers to stealthily get rid of or assassinate separatists or rebel cells on planets within the Galactic Fronter. Ministry of Truth addendum: While gene splicing is common to produce higher-yielding E-710 specimens, the Ministry of Science would never create a strain of termind to police its own citizens. Such talk is dissident speak and the implication that rebels exist is paramount to treason.

Trivia

 * Stalkers derive their name from a similar enemy in the first game. Like their namesake, they are agile ambush predators, who cloak themselves in order to approach unaware Helldivers. However, they are much deadlier than their ancestors, capable of both dealing and enduring far more damage.
