[X] 300 Xenomorph
Really wanted to vote for Xenomorph, fantastic at stealth and learns very quickly. Not to mention the movie released in 1979 so they have it on Bet and would be a great point of contention on whether his ability is just making projections and give Piggot a heart attack for knowing what they are.
Realistically he would never summon it, but the thought of one running around and performing stealth takedowns on gangers really makes me laugh, lest we forget we have non-lethal and trainer skills so a Xenomorph could make for an effective stealth operative for holdouts on enemy bases. Don't forget that we still have Coil to deal with too, a Xenomorph breaking in to his base has pretty high odds of success in my book, remember when all those highly trained space age marines didn't notice the xeno picking them off?
Ooh also Administrator Z did say they sometimes chose things for the CM, even when they don't want to, this is probably one of those few who made it in.
