Enemies: Women of Femizonia;
    Fantastic Four (Human Torch, Medusa, Mr. Fantastic, Thing), She-Hulk

Known Relatives: None (he never even knew he had a mother at all)

Aliases: The Nuclear Man

Base of Operations: Earth-Machus/Femizonia (Earth-715)

First Appearance: Fantastic Four I#151 (October, 1974)

Powers/Abilities: Mahkizmo possesses superhuman (Class 100) strength and durability, as well as being a savage warrior skilled in unarmed combat. In addition, he can release explosive force from his body sufficient to level a small building. This can be added to the force of his punch, or it can be released as an omni-directional wave.
    It may be that his maximum strength and durability is only achieved with conscious effort and tapping into some energy force, as he was once knocked out by a bottle being broken over his head.

    Mahkizmo is as macho as they come. Men rule the world; any guy not up to his standards of manliness is a girly-man. He lives for combat and conquering, although he really had no idea what to do with a woman once he had the chance. I think the most he ever understood was perhaps "feeling all funny, like when you climb the rope in gym class." (thank you Garth).

Height: 7' 6"
Weight: 505 lbs.
Eyes: Brown
Hair: Brown

History: Mahkizmo is a native of Earth-Machus. The exact source of his enhanced powers are uncertain

(Fantastic Four I#151-153) - He was sent back to the modern era to stop Thundra, who was trying to prevent the existence of Machus by altering the past. Mahkizmo appeared and quickly overpowered the Human Torch, Mr. Fantastic, and the Thing. Thundra attacked him, but he teleported her back to Machus, where he used an energy beam to sap her will and imprison her.
The Fantastic Four used Dr. Doom's time machine to travel forwards and "sideways" in time to follow them, but Mahkizmo and the Men of Machus defeated them (Mahkizmo did resort to threatening to kill Johnny to subdue the Thing when "Clobberin' Time" came around). Mahkizmo took his prize for the conquest, Medusa, to his chambers. Medusa entranced him with soft words and hands, brained him with a jug of wine, and then escaped back to the modern era. After recovering, Mahkizmo sentenced the Fantastic Four and Thundra to death in the gladiatorial pens. When they overcame all opposition, he entered the fight himself. Again he defeated the group (although this time it was revealed that they had all been subjected to his will-killing energy ray, too).
Medusa then arrived with the cavalry--the Femizons. Having used the time machine to go to Earth-Femizonia, she then brought them to Earth-Machus. The Human Torch destroyed the will-killing energy ray, allowing the Femizons and Machans to fight on equal ground. Mahkizmo summoned his energy for his devastating nuclear-punch, but Thundra and the Thing smashed him before he could release the force, and he was disintegrated by the energy implosion.
With Mahkizmo destroyed, the last barrier between the Earths (Machus and Femizonia) dissolved and the two worlds merged. The Machans and Femizons were all affected by the merging, and ceased their hostilities in exchange for sweet love.

(Sensational She-Hulk#39 (fb)) - Mahkizmo, was somehow maintained as an intangible, invisible cloud of atoms. Upon observing the harmony between the men and women, Mahkizmo was furious. He managed to direct his disembodied form into a man of the new world (the merged Femizonia/Machus), and transformed it into his own form. Since he had been spared the effects of the fusion, Mahkizmo was the only one who remembered how the world had been.

(Sensational She-Hulk#34) - Mahkizmo set out on a plan to set off the Gender Bomb, to kill all of the women of the past, to prevent the women of his timeline from existing. Mahkizmo then accessed a time machine of his world to travel back to the modern era.

(Sensational She-Hulk#38) - Mahkizmo arrived in the modern era and attacked the She-Hulk, apparently planning to humble one of the most powerful women of that era. They fought an even match, until Cupid, acting on a challenge of Venus, shot Mahkizmo with one of his arrows, and he fell in love with the She-Hulk. He abducted her to his world, with the intention of making her his bride (and then finishing up on the plot to kill the wimmens.

(Sensational She-Hulk#39) - They were followed by the Thing and Wyatt Wingfoot, who used Reed Richard's time machine to follow Mahkizmo's "temporal trail." The She-Hulk and the Thing combined their power and defeated Mahkizmo. Jen then explained to him why his plan wouldn't work they way he wanted it to (Birds and Bees and What-Not).
However, the arrival of the heroes from the modern era allowed the men and women to remember their pasts. This broke their unnatural spell of harmony and peace, and allowed them to beat the crap out of each other, just like good warriors should. Mahkizmo's assistant explained that these brawls were nothing more than household spats as played out by a race of warriors...and everyone lived happily ever after.

(Fantastic Four: Foes#1) - Mahkizmo attended a gathering of enemies of the Fantastic Four held by the Puppet Master, who suggested that they combine their forces. Occulus left with the others, without even acknowledging the Puppet Master's scheme, unaware that the Mad Thinker had obtained a DNA sample from him, as per his primary intentions.

(Fantastic Four: Foes#5 (fb) - BTS) -  The Fantastic Four captured Mahkizmo and transferred him to the newly constructed Vault in the Negative Zone.

(Fantastic Four: Foes#5) - Mahkizmo and the rest of the inmates were released from their cells by the Negative Zone sorceress Threska.

(Fantastic Four: Foes#6) - Mahkizmo and most of the other inmates fought the Fantastic Four, and they either voluntarily returned to their cells or were recaptured by force.
