Marius St. Croix

Energy siphoning: St. Croix has the ability to siphon mutant energy from the bone marrow of muants by way of the feeder mouths on his hands. If he siphons a person's entire energy force from his victim, they die. It is unknown how often he must siphon energy from another mutant to survive. When feeding from a victim, he cancels out their powers. He is also capable of using the powers he has siphoned. After multiple feedings, he gains the power permanently. Psionic detection: He has the ability to know various details about a mutant's powers and their surface thoughts and memories. This ability also makes him an excellent tracker, allowing him to locate individuals by innate knowledge and seeing their psionic aura.
 * Diamond skin: Due to siphoning power from Penance for so long, St. Croix possesses skin that is almost diamond-hard, making him highly resilient to injury.
 * Energy vampirism: If St. Croix drains only part of a person's energy, he achieves a measure of psychic control over that person's mind. Through unknown means, he can cause a mutant to become an energy vampire like himself.

Dimensional shifting: He has the ability to shift slightly outside of his dimension, into the space between dimensions. This gives him invisibility and phasing abilities on a somewhat limited scale.
