[9] The leader of the Neyaphem, Azazel, is the only one who is able to breach the dimensional void and return to Earth for brief periods of time due to his teleportation powers.

[8] He meets Mystique in Germany, when she is married to a rich castle lord named Baron Christian Wagner.

[12] It is later shown that Azazel was taking care of business involving the Cheyarafim, and had to leave, knowing that Mystique would find some way to live.

However, she doesn't have much time to formulate a plan, as the angry villagers soon find out about Christian's murder and come after her and the demonic-looking baby.

[14][15][16] Later, believing Nightcrawler is his son, Azazel sires several dozen other children as part of an effort to forge a permanent connection between his hell-dimension and Earth.

[17] Azazel's other children are all mysteriously called to gather and sacrifice themselves on the island known as the Isla Des Demonas to open a portal and bring his army to Earth, with the goal of destroying both the Cheyarafim and what Azazel calls "normal mutants", mutants whose bodies do not show signs of their mutation, and who are not seen as monsters and demons.

[18] Azazel's whereabouts are unknown for several years, but he resurfaces in this dimension, revealing himself to be the master of Calcabrina, former ally of Frankenstein's Monster, and banned from all realms of Hell.

Weapon X-Force is close in proximity, and Sabertooth grows agitated with the lack of progression towards the mission's goal, eventually having the team reveal themselves to attack Azazel, with the plan to force him to teleport them to the realm of Hell where Stryker now resides.

In order to send them to Hell, the Weapon X-Force are killed by Azazel, as they are all sinners who are already designated for eternal damnation anyway.

Due to all members of Weapon X-Force possessing powers of regenerative self-healing, Azazel is able to keep the entire team in suspended animation with the use of his teleportation abilities.

He enters through the teleportation gateway alongside other villainous and fractious mutants, who are invited to join the nation to heal mutantdom and start over as a species.

[21][22][23] However, Azazel decided to reject Krakoa and join the Goblin Queen in the Limbo Embassy along with Emplate, who became his servant.
