Martian Manslayer in a DC animated style

Martian Manslayer

(Evil Martian Manhunter)


This is an evil version of DC Comics’ Martian Manhunter.

The Martian Manslayer was part of a small cluster of variant version of iconic DC characters, but evil. This was inspired by several versions of the Crime Syndicate of America seen in JLA comics.


  • Real Name: Unrevealed (jokingly referred to as “J’imm J’onzz”).
  • Marital Status: Widower.
  • Known Relatives: Wife and Child (both dead).
  • Group Affiliation: None.
  • Base Of Operations: Mobile.
  • Height: 6’7” Weight: 290lbs.
  • Eyes: Blue Hair: Brown/Black, but usually bald.



The Martian Manslayer was a white Martian serial killer. He was hunted by other members of his peaceful race for numerous murders, including that of his own family.

He was transported across time and space by an Earth scientist, Dr. Erdel. Erdel was planning on performing experiments on the abducted alien, but was not prepared for the White Martian. The Manslayer locked Erdel in his own basement for a week, while the Martian systematically killed anyone and everyone close to the doctor.

He then called the police, unlocked the basement to release Erdel, and disappeared.

The Manslayer repeated this process numerous times through the following four decades. He eventually developed a preference for choosing celebrities as his victims, while transferring parts of their wealth into his own hidden bank accounts around the world.

Following his successful framing of football legend and role-model O.J Simpson for the murder of his ex-wife and her friend, he targeted former astronaut and Centropolis Police Lieutenant Clark Kent.

Kent, as Ultraman, made short work of the Manslayer. He uncovered evidence exonerating most if not all of the Manslayer’s targets over the years. But he decided to keep that information secret, leaving the innocents to serve out their sentences.


The Martian Manslayer was a chalk-white humanoid with a protruding brow similar to his JLA counterpart.

He preferred not to adopt any single human identity for too long, as it allowed him to distance himself from the crimes he committed in that form.


The Manslayer, when not assuming a specific identity, did his best to come across as serious, caring, and polite. Those meeting him would be hard pressed to find major differences between him and his green, heroic duplicate.

It was all a ruse. He was, in fact, a serial killer with no regard for any life and is fully aware that he has so much power that even other superhumans should rightfully live in fear of him.

Optional GameMaster Note

I’ve been re-reading Stephen King’s It, and it struck me that the monster in that book used a fair bit of mental and shapeshifting abilities. It spends it’s time tormenting and then murdering small children. I figured this would be a great pastime for our little Martian friend.

Similarities abound.

In the book, the people in the town (Derry, Maine) have a decided mean streak to them. In several instances, it’s mentioned that there’s something “wrong” with the town. The murder rate is six times the average for towns of it’s size. There are 40-50 child disappearances a year (in a town of 35,000).

People just don’t care about their fellow man (several people just stand by and watch as someone is murdered, people drive by and don’t lift a finger as one kid tries to stab another). Everyone just thinks “It’s not my problem.” Sounds a lot like the Anti-Matter Earth to me.

The monster itself makes people see things. A picture of the hero’s dead brother looks up and talks to him. Then blood gushes out of the page. Voices come up through the drain in the sink. It takes on the form of people’s worst fears (anything from a dead, rotting kid to a werewolf, to a bum with leprosy, to Rodan) and then tries to kill them.

It’s “default” form is a white-faced clown. Creepy. And the Martian Manslayer is a *white* Martian. 🙂

Maybe Derry is where he hangs out when he’s not framing superstars. He’s been here since the 50s, right ? That’s a lot of time to kill. And even Martians need a place to call “home”.

Bonuses and Limitations:

  • Adaptation works for Mental Skills only and only works on those against whom the Manslayer has successfully performed a Mind Probe.
  • Dispersal allows partial dispersal and is not impeded by force fields.
  • Invisibility requires incredible concentration to use, so he cannot use any dice actions while invisible without first making a Int/Will vs AV/EV of the action he wants to attempt. This counts as an automatic action, not a dice action, for the phase. If he fails the check he becomes visible instantly.
  • Self Manipulation allows him to shape his body in a free form manner, controlling each molecule mentally. He however cannot gain physical abilities he does not already have that aren’t suggested solely by the form itself, such as Extra limbs and so on.
  • Density Increase and Growth can only be used when on a planet (-1) ; unless that planet is Mars, all of MM’s Powers acquire a Serous Burnout until he ejects the alien mass or replaces it by Martian dirt (-2).
  • Powers that burn out can either cease to function or function unpredictably (-1).

Genius, Lightning Reflexes, Omni-Connection.

Attack Vulnerability (Fire and Flames: -3CS), MIA (to use the GURPs term, Murder Addiction).


The Manslayer’s Dispersal applies its APs normally to his defenses against physical and energy attacks but he ignores force fields entirely. The Manslayer often uses his Self Manipulation extend his limbs to long lengths (by giving himself Stretching of usually 3 APs).

He also can gain abilities that are physically a part of the body he is mimicking, such as gills, wings, claws etc, but abilities created by a metagene or magic he cannot produce.

He cannot produce effects that are properties of the body but are dependent upon glands, or other biological properties those bodies have that his does not.
