Zzzxx: the weirdest Symbiote you've never heard of

Ok so I've kinda fallen down this extremely shallow rabbit hole;


This is Zzzxx- apparently, one of the top 5 most dangerous prisoners ever held by the Shi'ar Empire (alongside someone with the same powers as Gladiator and a living sun, as an example of who he's being compared to). Why is he so dangerous? ...We don't really know. Why was he kept alive? Apparently, he's unique in some capacity- unique enough that the leader of the empire himself wanted to study 'em. How is he unique? We kinda know, but not really.

This guy is REALLY obscure, showing up originally back in the 2000s for a few issues when Vulcan took over the Shi'ar, eating the Cancerverse version of Professor X- who was just a football stadium sized brain- and then disappearing until a recent Marauders comic. Apparantly, something about him was so interesting, some Shi'ar decided to turn him into a bioweapon called "wet skin" that let them weaponize their blood. Cassandra Nova fixed him, and now he's bonded to a Shi'ar supersoldier named Warbird after having a total personality shift.

Oh, and he has an X-Gene? Like, he's not just a mutant in the generic sense, he literally has an X-Gene, which normally are exclusive to human or human hybrids. We don't know why, how, or what it does, but yeah- he has one.

Very strange symbiote. Given his affiliations, hoping to see him in Hickman's upcoming Imperial book.
