Some general ideas...
Assasskin - Sectillian Assassin Bug type Warlord with a full suit of armor made 100% from zombie cadavers. Convinces less intelligent undead that he is one of them, be it the suit itself or some other latent ability. Down side is every other nitwit out there thinks he's undead, too. "Armor" is still un-living and may provide some benefits as such.
Captain Carcass - Mangled undead "super-hero" who is in this state due to being self-dilluded and thinking he has powers. Acts like a mix of Adam West Batman and Boyscout Superman, but with surprising bloodlust and murder streak he plays off as "a dirty job someone has to do." Treats creatures in his aid like members of a super-team, giving them ever-changing monikers such as "Professor Horrible Sucking Face", etc. Cape is just his back skin peeled away from his trunk, and he wears a mumbling zombie face sewn to the center of his chest. He will occasionally rip off a limb and attempt to use it as a "Gangrerang". Came from the corpse sea, a meteorite hit him in the head and still juts out from the side. Supposedly, it enhanced his intellect though that's debatable.
Mr. Mutanus - A mild-mannered, vaguely inhuman-looking kindly old white-haired Doctor-type on par with a Lester. Drags around a tremendous, distorted, tumorous decaying ass and leaves behind a trail of mutating gel. Beware his gas and the occasional emerging of the unnamed Gillman parasite within.
Phone - A bioconstruct vaguely resembling a shambling, twisted call center that refuses to die. Antennae randomly placed all over its largely amorphious, fleshy body is used to transmit signals to anyone in the vicinity who is seeking to procreate. It will then as "what are you doing with my son/daughter?" at which point the recipient of this psychic message will feel a strong need to follow the signal and become one with the writhing mass.
Either way I will have an adoring Leslie.
