History: Little is known about Marius St. Croix before his mutant powers manifested and threw him into a pocket dimension. In the pocket dimension, Marius discovered that he could return to Earth by feeding on the marrow of mutants. During this time, Emplate found the mutant known as Penance, captured her, and used her as his primary source of sustenance.

In an effort to gain power, Emplate intercepted the mutant Chamber as he was arriving in the United States. Emplate was stopped by Chamber and the members of the mutant team Generation X, which included his sister Monet. Later that day the aborigine known as Gateway rescued Penance from Emplate's capture, and brought her to the newly re-opened Massachusetts Academy, which housed the rest of Generation X.

In order to recapture Penance and Chamber, Emplate teamed up with a number of mutants, humans, and mutants he had enslaved with his mutant power, including Lady Gayle Edgarton, who had lost the use of her legs when Chamber's powers manifested. Renaming themselves the New Hellions, Emplate and his slaves attacked the Massachusetts Academy. The New Hellions were driven back by Generation X with help from the X-Man Bishop. Emplate was defeated by Penance, who betrayed him as he was about to kill Generation X. Before his defeat, however, Emplate managed to enslave the Generation X member Synch, turning him into an energy vampire such as himself, and Synch was teleported to his home town of St. Louis. With the help of the mutants Jubilee, Husk, and M, Synch was able to resist Emplate's influence and return to human form.

Recently Emplate and M temporarily fused into a single being called M-Plate.

(Note: The mutant Bishop has claimed that in the future he hails from, the Xavier Security Enforcers battled creatures called Emplates in the thousands. What if any relationship these creatures have to the present day Emplate is unknown.)

Known superhuman powers: Emplate is a mutant who must feed on the bone marrow of mutants in order to remain in this physical plane. He feeds on his subjects by physical contact with fanged mouths that are embedded in the palms of each of his hands. If he is denied sustenance, Emplate is thrown into a pocket dimension where he is the subject of constant torture. He is also able to absorb the powers of a mutant that he feeds on for an extended period of time. With the exception of Chamber, a mutant is unable to use his or her power while being fed upon by Emplate.
Emplate is able to turn anyone he chooses, presumably by physical contact, into a creature like himself, requiring the enslaved human or mutant to feed on mutant bone marrow. It has not been revealed whether this transformation is permanent, if the subject could willingly fight it off, or if Emplate can reverse the process.

Limitations: Due to extensive physical damage that Emplate has suffered while in the pocket dimension, he is unable to survive on Earth without the use of a respirator. The length of time on Earth that Emplate can survive without a respirator is unknown.
