[1] As a race of shapeshifters, physical appearance has little meaning for Martians, and the Greens and Whites are only separated by underlying psychological differences and philosophies, with the former being more peaceful and the latter more violent.

[2] In the current DC continuity, their preferred form is that of angular, hairless humanoids with chalky white skin with bony, armor-like ridges or plates.

The timeframe for this genetic tampering was given as 20,000 years ago, contemporary with the early life of Vandal Savage on Earth, in JLA series 2 #86.

[6] The Hyperclan members are known as Protex, Fluxus, A-Mortal, Züm, Primaid, Tronix, Armek and Zenturion, using the array of natural Martian powers to give each "hero" a seemingly different set of abilities; for example, Züm was a speedster, Armek was a massive armored figure with superhuman strength and could change color, and Fluxus was a shapeshifter.

Their initial attack results in the destruction of the League's satellite and the death of Metamorpho and is preceded by a sickness that strikes all fire-based heroes and villains, such as Firehawk and Doctor Phosphorus, causing them to lose their powers.

Despite the heroes scoring some victories in later confrontations, such as the Flash knocking out Züm with a punch at near-lightspeed or Green Lantern taking out Armek by exploiting the fact that they thought his ring was still vulnerable to yellow, the Hyperclan eventually managed to capture all of the Justice League, keeping Superman tortured with a mental illusion of green kryptonite while trapping Wonder Woman, Flash, Green Lantern and Aquaman in the 'Flower of Wrath', a device that would kill the heroes in hideous agony when it closed, with Martian Manhunter having apparently decided to betray the others out of recognition of the fact that he would never be accepted.

After Superman issued a public broadcast to the world that warned them of the threat and the Hyperclan's weakness, the invaders were captured, and each of them was telepathically brainwashed by J'onzz and Aquaman to believe themselves to be human.

Given strong mental blocks to inhibit their powers, the Martians assumed normal Earth lives all over the globe, although they were kept under observation by the League.

Whereas before evolution would have eventually made mankind into a race of superhumans similar to the Daxamites and Kryptonians, or the Martians themselves, now only a select few humans would be able to develop metahuman powers.

This time, the White Martians captured various human psychics to work on means of expanding their own mental abilities while simultaneously constructing chemical processing towers which would fireproof Earth's atmosphere by binding all the free oxygen, making themselves completely invulnerable, and conveniently asphyxiating mankind into extinction.

Released by the Atom (who had hidden inside Protex's head to use his own telepathy against him), the League faced the Martians in a climactic battle on the Moon.

Placed in this position, the Martians were forced to accept being banished into the Phantom Zone — a common punishment for DC's most dangerous super-villains — or die on the Moon.

The Sons of Vulcan passed the metavirus down in an unbroken line from then onwards, sworn to hunt and kill "the pale ones", i.e., the White Martians.

In Teen Titans vol.3 #41, Miss Martian was shown quickly recovering from the effects of Bombshell's neural scrambling powers as well as reforming after (apparently) having her head shot off.
