Xenomorph Aggressor (Earth-5875)

"We'd better get back, 'cause it'll be dark soon, and they mostly come at night... mostly."

- - Rebecca "Newt" Jorden

Aggressors are one of the primary forms of the xenomorphs, and as a result, one of the most common of them all. Fast, strong and lustful for enemy blood and survival, the xenomorphs pose a formidable physical threat despite the advanced technologies of both the UNSC and the former Covenant hegemony, with their blood being deadlier even after their deaths. They are noticeably taller than Lurkers, and are also distinct duo to their ridged heads.
