S-Hawk resembles Mihawk as a child, but is significantly larger in size. He also possesses lunarian traits, such as brown skin, black wings, and white hair. His irises have additional rings similar to Mihawk's, but his pupils are star-shaped like the other Seraphim. A section of his right forearm is replaced by a tube that is filled with Green Blood. S-Hawk has not displayed any personality outside of his obedience to the Marines and Vegapunk and aggression towards his designated targets. Zoro has regarded S-Hawk as possessing more humanity than the original Dracule Mihawk. S-Hawk is one of the Seraphim, which Vegapunk describes as the pinnacle of his scientific achievements and the "Strongest Form of Humanity." Like other Pacifista, S-Hawk was given the ability to fire lasers from his palm as a result of Vegapunk's research. As an artificial lunarian, S-Hawk possesses flames on his back that are linked to his tremendous resilience as a lunarian. S-Hawk is sturdy enough to withstand Blackbeard's attack, and also a combined attack from Roronoa Zoro and Kaku. Like the original Mihawk, S-Hawk is an extremely skilled swordsman. His attack forced Blackbeard to use Armament Haki for defense and sliced off a large portion of Amazon Lily's central mountain. He was also able to hold his own against Roronoa Zoro, a tremendously powerful master swordsman. Via the Green Blood, S-Hawk possesses an artificial version of Daz Bonez's Supa Supa no Mi, allowing him to turn any part of his body into sharp steel blades. He has used this ability to transform his leg into blade to augment his kicks and create a ranged slicing attack. S-Hawk's usage of the Supa Supa no Mi mirrors that of Daz Bonez, as like him he attacks with a variety of hand to hand techniques that are enhanced by the effects of his Devil Fruit. Similarly to Daz Bonez, he also has the ability to sprout blades on his feet, allowing him to skate on solid ground as if it were ice. S-Hawk is able to use Observation and Armament Haki. S-Hawk wields a sword shaped similarly to Yoru, though it is less ornate and its blade is not black.
