The Vile Menagerie: MARCO XAVIER
Occupation: Playboy; Sportsman; Crime Czar
Marital Status: Single
Known Relatives: None
Group Affiliation: Vulture
Base of Operations: The Mediterranean
First Appearance: House of Mystery #160 (July, 1966)
Height: Approx. 6"
Weight: Approx. 170 lbs.
Eyes: Dark
Hair: Black
History:
Little is know of the past life of the wealthy mystery man, Marco Xavier. Behind the high iron gates of his posh Mediterranean villa, he lived alone, with neither friend nor relative. Called by some a "very stubborn... lone wolfer," Xavier maintained his fortune by working with illicit operations, but never as a dedicated member. Still, his reputation of being reliable in performing "extra-legal chores" was "well known in underworld circles." The internationally famous playboy was eventually linked to such shady figures by a special security department, which in fact appeared to be their only lead in investigating the most sinister criminal organization on Earth, Vulture. Mr. Steele brought in J'onn J'onzz, the Manhunter from Mars, to pursue this lead. However, as soon as the Alien Ace began observing Xavier, he bore witness to a seemingly fatal car accident, as the playboy careened through guardrails on a winding mountain road and plunged to a fiery explosion below. Thinking quickly, the shapeshifting Martian assumed the guise of Marco Xavier, dangling from an outgrowth to be "saved" by local authorities.
Xavier appeared to have at least one named servant, a gentleman named Jeffers, who ushered in agents of Vulture to meet with "Xavier" the morning after the accident. Despite the assertions of Mr. Steele, Xavier had a highly desirable number of associates and friends, whom Xavier would be paid to spy upon or otherwise sabotage-- among them, notable magnates such as Apollo Magnus, Miklos Agar, Aldo Szuzi, and Pierre Carré. Marco Xavier appeared to have been quite the ladies man, often followed by a "bevy of beauties;" from doting socialites to dating secret agents, who he referred to frequently as "chicks." These assets seemed to help the faux Xavier maintain high value with the Faceless leader of Vulture, Mr. V.
After some time with J'onn J'onzz active under the guise of Marco Xavier, assisting Vulture in various plots, he received his final assignment. Manhunter/Xavier stole "the ultimate weapon" prototype pistol from The Carré Company, swapping it for a replica, but the deception was soon detected. Marco Xavier was finally wanted by the police for a specific crime, limiting his usefulness to Vulture, who still owed him a million dollars for the heist. After repeatedly evading authorities, Manhunter/Xavier was picked up by Vulture operatives, and taken to a tiny island on the opposite side of Mediterranean from his villa. This was a different location from where the pistol had been taken, and another high-tech underground Vulture base, which explained why the Manhunter had not detected it in prior surveys.
"Xavier" was led to Mr. V, who unmasked to reveal "Faceless" as Marco Xavier. Supposedly, one of Vulture's men had posed as the gendarme who had pronounced Xavier dead after the accident. It was declared that Vulture had been toying with the Manhunter from Mars the entire time, until they could deduce his secret weakness of fire. This Marco Xavier had continued the masquerade until he could lure Manhunter into "the perfect trap!" Rather than simply roast the Martian alive, and apparently "insane with power," this Xavier targeted Manhunter with the purloined prototype. It immediately exploded, wrecking the Vulture base, and presumably killing Marco Xavier before the Manhunter's eyes a second time.
Quote: "HA-HA! And now, while there still remains a breath of life in you, I shall test the ultimate weapon-- on my favorite target-- you!"

2014 Houston Comicpalooza Marco Xavier Vulture Jam Sketch Detail by Brian Denham
- 2023 Fan Expo New Orleans Darkman Commission by Derec Donovan
- 2023 Fan Expo New Orleans JLA JAM The Flash segment by Derec Donovan
- Image Comics 25th Anniversary Jam Savage Dragon & Friends detail by Evan Dorkin
Brian Denham was one of the very first artists that I ever commissioned, and the first take home piece, too. I love his work, and wish there was more of it. He used to be a regular at Houston shows, and I think he was living elsewhere in Texas, so I took his presence for granted a little bit. I've been sitting on this piece for eleven years, and I'm not sure if Denham has been back to town since. The previous portions of this jam had all been stacked up more or less vertically on one half of the pages, with the common theme of the subjects having appeared in Vulture tales from House of Mystery. This international criminal organization was routinely undermined by the Manhunter from Mars in his then-new public identity of Marco Xavier. J'onn J'onzz had stolen the identity from a wealthy playboy with ties to Vulture, and as the story progressed, it became clear that Xavier was a much bigger part of the outfit than originally thought. I'd hoped to have a Marco Xavier biographical profile up by now, and hope to work on that throughout September, while tossing off shorter pieces from that period. If all goes according to plan, I'll also have the finished jam up by October. But I've promised less and failed to deliver, so we'll see. I can't say the same for Denham though, as his take on Marco Xavier is the centerpiece of the jam. This is from a color photocopy from before additional contribution were made on top of it, so the colors are a little off, but hopefully they'll be better represented in the final scan. There's a sense of finality that comes from finally releasing these aging pieces and collecting them with others that are over a decade old. I wish that were not the case, but again, we'll see what the future holds...

2014 Houston Comicpalooza Abba Sulkar, Shtarker, & Grosse Vulture Jam Sketch Detail by Isaiah Broussard
I'm confident that Isaiah Broussard drew Perkins Preston near the start of the 2014-2016 JLI, Saturnians, & Other Friends Artist Jam, which means Comicpalooza, and Elongated Man at or near the end of the 2015-2017 Martian Manhunter Comrades Jam, most probably at Charlotte HeroesCon 2017. I didn't think that I started this jam at the same show as the earliest attempts, so now I'm wondering if it was the 2015 Space City Comic Con, or maybe that year's Comicpalooza? But I already laid claim to the date/show on other posts, so...
I also can't recall if Broussard was the first or second contributor to this one, but given the other subject, probably second. Anyway, I dug what he did with Abba Sulkar and his minions, and having the lot of them helped a lot with the ultimate scale of the piece. Sulkar is a normal-sized dude, while Shtarker & Grosse were Martian Manhunter-sized. When you start putting characters in front or behind them, it shows just how titanic most of these menaces were. Looking forward to you folks seeing the final two(?) characters, but I'll probably start offering segments from another jam in the lead up to the blog's 18th anniversary in September, when I do the full reveal of many/most of these long-mothballed pieces. And with any luck, by October I can get to the last of my Broussard commissions, although that one's not even comics related.

The Vile Menagerie: SULKAR
Alter Ego: Abba Sulkar
Occupation: Spy
Group Affiliation: Vulture
Base of Operations: Taurus Mountains, Turkey
First Appearance: House of Mystery #161 (September, 1966)
Height: Approx. 5'8"
Eyes: Light
Hair: Brown
History:
Abba Sulkar was the leader of a Vulture base in Turkey. Among his operatives were the towering brutes Shtarker and Grosse, as well as the lovely double agent Marie Fouchere. Sulkar was tasked with kidnapping a pair of scientists to drain their brains for evil purposes. Without clear motivation, Sulkar had Fouchere use her past romantic history with international playboy Marco Xavier to lure him to Sulkar for the same treatment. Successful, Sulkar explained his actions to Vulture's leader, and despite being ordered by Mr. V to set the tape of Xavier's stolen memories aside for his personal viewing, Sulkar wanted any secrets Xavier held for himself. Discovering Xavier was secretly Vulture's great enemy, the super-heroic Manhunter from Mars, Sulkar set about killing the mindless "Marco Xavier" while he was vulnerable in human form. However, Marie Fouchere double-crossed Sulkar to free the Manhunter, and Sulkar was killed in the resulting confrontation.
Weapons:
Aside from his advanced hidden mountain base, Sulkar utilized a pair of novel weapons. He possessed a large computerized device that could project a ray capable of extracting all memories from a victim. Aside from basic motor skills and autonomic nervous function, the victims did not appear to possess any meaningful thought processes or capabilities. The stolen memories would then be recorded onto some form of magnetic tape before being processed for permanent record storage and retrieval. The memories could then be restored to the victim, if so desired. Next, stolen memories could be reviewed on a monitor screen to exploit the subject's knowledge. The Disintegrator Weapon was Sulkar's other key asset, capable of nigh-instantaneously rendering a human being into a small pile of ash. The weapon came in the form of a handheld pistol, bulky but still operable with one hand. While the weapon was utterly ineffective against the Manhunter from Mars, it made short work of Sulkar, when he accidentally fired upon his own person.

The Vile Menagerie: MANHUNTER'S DOOM
Occupation: "Suitable Opponent"
Group Affiliation: Vulture
Base of Operations: Europe
First Appearance: House of Mystery #170 (October, 1967)
Height: Approx. 15 ft.
History:
After Mr. V had compiled an extensive photographic dossier of Vulture's run-ins with the Manhunter from Mars using hidden cameras, he paid international playboy Marco Xavier to analyze the material to determine Manhunter's weakness. Concluding that Faceless would inevitably come to the same conclusion, the Manhunter, in his Marco Xavier guise, revealed his Martian vulnerability to fire. Within a month, Mr. V tasked his scientists to construct a warrior that would end the threat of the Martian Marvel to his criminal organization. It was then deployed to the estate of Baron du Marchal, a friend of the Manhunter's, whom Xavier had confirmed would host the Martian that week. After a brief struggle, the Alien Atlas disabled the opponent by dumping it into a pool. Despite never managing to seize the Manhunter or use its flame, Mr. V. dismissed his construct and assumed Xavier's conclusion as to the vulnerability was in error.
Powers & Weapons:
The robot's body was made from the same heat-resistant compound as rocket shields, containing a jet burner at its core capable of melting a steel wall. In its head rested a transistorized computer, preset to hold the Manhunter against its body and release the internal flames.

The Vile Menagerie: MONSTER-MAN
Alter Ego: Joe
Occupation: Henchman
Marital Status: Unknown
Known Relatives: Unknown
Group Affiliation: Vulture
Base of Operations: United States
First Appearance: House of Mystery #166 (April, 1967)
Height: Approx. 9'-10'
Eyes: Dark
Hair: Dirty Blond
History:
Once, Vulture developed a molecular-ray that could temporarily transform normal men into hulking man-monsters. The most highly visible subject was an agent simply called Joe, who used his new power to rip open an armored car with his bare hands. Mr. V sought to make the process permanent, and scientists at one of his international labs developed a cylinder that could potentially do the job. However, authorities were aware of the Monster-Man's crime spree and Vulture's plot, so they were on high alert to intercept the cylinder when it entered the United States. Mr. V paid the globe-trotting playboy Marco Xavier for the task, as he would be above suspicion. However, the real Marco Xavier was presumed deceased, and his identity assumed in recent months by the Manhunter from Mars.
The Sleuth from Outer Space raided the hideout where "Xavier" had taken the cylinder, but soon determined that this was but one safehouse, not the location where Vulture was keeping the ray. The Alien Atlas traded blows with Monster-Man for a bit, then feigned defeat in a bid to follow the Vulture agents back to their true headquarters. The plan was wrecked when the Manhunter's former partner Zook crashed the scene, and when his own powers faltered before Monster-Man, the Manhunter blew his ruse to save his other-dimensional pet. Just then the ray wore off, leaving Joe just another Vulture bum taking a concussion nap until the police arrived. Manhunter did eventually find the base, and destroyed the molecular-ray before any more Monster-Men could be produced.
Powers:
Monster-Man displayed incredible strength and durability, especially to Zook's deep freeze power. Yet, it wasn't seemingly in the same class as the Alien Atlas, who easily overcame Monster-Man when so inclined.
Weaknesses:
The Monster-Man is a limited time offer of undefined length, and will swiftly and spontaneously fade once its charge dissipates.

Mars & the Duke of Deception
In the Golden Age, the Roman God Mars ruled from the planet bearing his namesake, where he gathered the souls of dead men to serve as eternal slaves to his kingdom. Under Mars were three commanders, Lord Conquest, the Earl of Greed, and the Duke of Deception (along with General Destruction and Lya.) Mars and his lieutenants often deployed forces from the planet Mars against their sworn enemies, the Amazons, and their greatest champion, Wonder Woman. Initially, these "Martians" appeared to be Caucasian humans, perhaps related to those enslaved souls, but later, native Martians were clearly deployed.
At one point, Duke Deception overthrew Mars to rule their planet, and later commanded a fiefdom over Yellow Martians, whose form he assumed to lead them in a combined invasion force alongside armies from Saturn and Jupiter. This was after Deception had gathered representatives from planets throughout the Solar System in a bid to join together to invade Earth, but they were put off when Princess Diana made an impressive demonstration of potential resistance in "The Olympics of Terror." Later still, after an unexplained separation from his prior army (which may have involved the machinations of Morpheus,) the Imperator of Illusions assumed a green-skinned form, and was surprised to make the acquaintance of actual Green Martians. For a sprawling arena of natives, the Master of Matter tasked Wonder Woman in the Martian Olympics of the Doomed, but the Amazing Amazon bested him in the crooked competition. In revenge, the Green Martians destroyed the Earth, but with the help of a Jovian, Princess Diana traveled back through to prevent the destruction before it began.
Mars himself pitted against Wonder Woman the Crimson Centipede, a powerful green-skinned being, and a Martian creation bearing roughly sixteen arms and legs. Meanwhile, the Duke of Deception disfigured Wonder Girl, and tried to use her as bait for the Wonder Family to be cut down by a Martian fleet, but was thwarted. After a final invasion attempt on Paradise Island with Martian saucers disguised as an Amazonian Swan Fleet, the Duke of Deception was commanded by the Lasso of Truth to return to the Red Planet, from which the Martian incarnation of the Imperator of Illusions never returned. This final return took place before the seeming destruction of Mars in the inferno of The Blue Flame.

Batman '66 Meets the Legion of Super-Heroes (September, 2017)

In another one-shot comic book continuation of the Adam West / Burt Ward television sensation, Batman is transported by teenagers from the future to the year 2966 to solve a time-heist engineered by one of his dastardly fiends of 1966, Egghead. At one point, "Bat-Gramps" argues for deductive reasoning over computer logic with an overly-dependent Brainiac 5, which plays out in the form of a board game. Mr. Mxyzptlk cameos as a series of misdirects on the board.
"Concerned Citizen Recalls Seeing Bald-Headed Man," Go Ahead 2.
"Same Citizen Saw A Suspicious Bald Man On Mars," Go Ahead 1.
"He May Be Bald, But He's Also Very, Very, Green," Return To Earth.
To my knowledge, this is the only small appearance of J'onn J'onzz in the TV show continuity, and also a nice nod to the unused JLA Monopoly art of the special's creator, Michael (& Lee & Laura) Allred.
Speaking of slight appearances, September 1st marked the twelfth anniversary of this blog, and I believe that this is the first year that it went unmentioned. If not for the Salvation Run coverage this past summer, you'd be forgiven for fearing the worst. September was always a slow month for the blog in terms of readership, vastly more so since I stopped regularly updating. Frankly, I had other things I needed to get done more this month. That said, the original Z'Onn Z'Orr: Home of the Martian Manhunter and Martian Manhunter: Rock of the JLA Web TV fan pages would also be celebrating their 20th anniversaries around now. I won't pretend to foretell the far future after so many false starts, but an awful lot of artists have waited a long time to see their commissions turn up online. Wouldn't it be nice if I got out a weekly post every Martian Monday going forward?
