Marcus in combat
Vampire Dominant Hybrid Physiology: Because Marcus was the first Vampire, his powers were superior to those of the rest of his kind, including those of even Viktor and Amelia. His transformation into a Hybrid greatly enhanced his already-formidable powers and granted him the ability to transform into a humanoid bat-like creature at will. He had enough control over his transformation that he could turn only his hand into a claw as well as summon his wings, and could presumably change other parts of his body and was even able to talk while transformed.
Due to his age, he was also a skillful hand-to-hand combatant and likely versed in weapons use, at least those of the medieval kind, such as swords, as he is seen using one to attack his father.

- Superhuman Strength: As the first of his kind, Marcus possessed physical strength which surpasses that of any other Vampire, including Viktor and Amelia. After his transformation into a Hybrid, his formidable strength was further enhanced, as shown when he lifts a massive, solid stone door to reach William (albeit with great difficulty), pulling down a helicopter from mid air using one of its cables and overpowering other Hybrids, such as Michael, on various occasions.
- Superhuman Endurance: Marcus was able to endure multiple injuries, including being partially crushed by a small truck, sustained multiple gunshots at point-blank range, having one of his hands destroyed by a helicopter blade, having one of his wing talons broken, being stabbed through the brain by said talon (though it did stun him) and is only killed when Selene pushes him against the same helicopter blades, thus tearing apart his body.
- Superhuman senses: In addition to the powerful senses Marcus possesses as the first Vampire, he also has a strong bond with his twin brother, William, that he was able to sense his presence in proximity to the village he had single-handedly destroyed.
- Superhuman Healing: Marcus had a very potent healing factor, given his age and status, which was only further enhanced after becoming a Hybrid. He was able to recover from various severe injuries due to being partially crushed by a truck in only a few hours. Though his healing factor does not seem to allow him to survive dismemberment.
- Superhuman Speed: As a Vampire Elder and later Hybrid, Marcus could move, fight and fly at great speeds that only a few could react to.
Marcus has the ability to fly thanks to his wings.
- Flight: Due to him being a Vampire Dominant Hybrid, Marcus developed a pair of bat-like wings that can deploy and retract into his back. The tips of his wings were also extremely sharp and could be used as weapons to impale, hook onto, or slash his opponents.
- Blood Sorting: Like all Elders, Marcus could read a person's memories by drinking their blood. Marcus was shown to be exceptionally skilled in this ability as just by drinking Kraven's blood he not only gained his memories but also quickly learned how to use advanced technology such as computers and presumably other modern gadgets.
- Sharp-Razor Claws: Marcus as a Hybrid also has developed retractable claws, which are used for offensive purposes, such as cutting and slashing his victims as well as his opponents.
