Supernatural/Demon Physiology: Mephisto is a Class Two Demon, and possesses vast supernatural power, which is apparently inherent within him. He is energized by sources of evil in the human world.
Superhuman Strength: Mephisto possesses some degree of superhuman strength. He is capable of using his magical powers to augment his strength, enabling him to lift well in excess of 100 tons.
Superhuman Speed: Mephisto is capable of running and moving at speeds greater than even the finest human athlete.
Superhuman Stamina: The various mystical energies flowing through Mephisto's body augments his musculature so that it generates virtually no fatigue toxins during physical activity. As a result, Mephisto possesses almost limitless superhuman stamina.
Superhuman Durability: The tissues of Mephisto's body, while similar in appearance to a human's, are considerably tougher and more resistant to injury than the tissues of a human being. Mephisto's body is virtually invulnerable to conventional injury. He is capable of withstanding great impact forces, high caliber bullets, exposure to temperature and pressure extremes, and powerful energy blasts without sustaining injury.
Regenerative Healing Factor: Despite his superhuman durability, it is possible to injure Mephisto. However, his unique physiology and mystical energies enable him to rapidly recover from almost any form of injury. He is capable of regenerating almost any damaged or destroyed tissue, even missing limbs.
Immortality: As a demon, Mephisto is functionally immortal. He is immune to the effects of aging and is immune to all known Earthly diseases and infections. Mephisto is also beyond the need of food, water, or oxygen.
Magical Manipulation: He can control magical energy for various effects, among which are the augmentation of his own physical strength, levitation, teleportation, the projection of mystical energy as force blasts, invisibility, matter manipulation, image projection, size transformation of his body or other objects or beings, the creation of temporary inter-dimensional apertures, and so on.
Shapeshifting: Mephisto is more of a force than a physical being, one that can take any form that he wants. His "normal" appearance is that of male, red skinned humanoid with vampiric aspect and attire. However, Mephisto can appear in any form imaginable, having turning himself into animals, humans of any gender, or more commonly into other demonic forms, ranging from a stereotypical image of Satan to a giant reptilian monster. During his confrontation with Doctor Doom and Doctor Strange, Mephisto briefly turned into a inconceivable incarnation of evil with numerous misshapen images within him. Mephisto can also enlarge himself to intimidate and easily defeat his enemies.
Ensnare Astral Bodies: Mephisto also possesses certain powers enabling him to capture and detain the astral bodies (sheaths of the soul) of recently deceased human beings. Mephisto does not have jurisdiction over all the souls of humanity's recently deceased. It is not yet known what the prerequisite conditions are for him to be able to manipulate a human soul, nor are the precise means by which he accomplishes the feat known. Apparently these conditions require that the human being in question willingly agree to submit to Mephisto's will. It is not known how a human being may free himself from bondage to Mephisto (although Johnny Blaze apparently did), nor whether Mephisto will forever retain control of the souls he has obtained. Nor is it known whether or not Mephisto "feeds" on the psychic energies of such souls as other demons do.
Mystical Deal: Through a Faustian bargain, Mephisto is able to fulfill almost any wish that someone wants in exchange for something that they have - usually their souls. Once the agreement is sealed, it is virtually impossible for the victim to escape compliance. Mephisto can then use this deal to keep his victims always under his control, being able to even prevent them from remembering they made a deal with him, although the victims will still be able to recall vaguely that. Generally, only Mephisto himself can undo his deals with his victims, although depending on the nature and terms of the deal they made, victims have the ability to free themselves on their own.
Mystic Bet: Similar to their Faustian deals, Mephisto can make a sort of magical bet on the outcome of how an event will turn out. If he wins, Mephisto can demand what he wants from his victim, however, if the devil loses, he is obligated to give what the winner of the bet asks of him, even if it means undoing his deals.
Dimensional Entrapment: Apparently Mephisto can entrap a living human being within his realm through sheer physical force, even if the person did not submit his or her will to him. The woman named Topaz was thus entrapped until her recent escape.
Netherworld Dimensional Power Tap: Among the demons of various extra-dimensional netherworlds adjacent to Earth, Mephisto has few rivals in terms of personal power and scope of influence, although Satannish has stalemated him in battle. Mephisto's power seems to be connected to his extra-dimensional domain and diminishes over time spent away from it. Therefore, he usually sends demonic agents to do his bidding.
Reality Manipulation: Mephisto was able to create the realities Earth-7161 and Earth-71241 by creating a small alteration in the Earth-616 reality. As part of a deal with Peter Parker and Mary Jane Watson, Mephisto wove the Earth-81545 reality into Earth-616. However, this ability does not seem to be completely permanent, as some changed aspects of the life of Peter and Mary Jane were later undone.
Penance Stare immunity: Ghost Rider's Penance Stare doesn't affect Mephisto; to the contrary, it makes him stronger, due to that power making its victim relive all of its misdeeds at once, as well as the fact that he has no soul.
Medium Awareness: Mephisto possesses an unknown degree of medium awareness, able to pause a battle between himself, Doctor Strange, and Victor von Doom to monologue to the reader of the comic.
Precognition: Through a magical ritual, Mephisto is able to see the past and possible futures of those who wish to take souls. He can also see his own future.
Highly Skilled Liar & Strategist: Mephisto is an experienced and highly skilled liar and strategist.
Sorcery: He is also a highly skilled sorcerer with near infinite knowledge of arcane and occult subjects.
A fight between Mephisto and Hela would make Ragnarok pale in comparison and cause omniversal armageddon.

Weaknesses[]
Despite his immense power, Mephisto does have several significant limitations. He is unable to force the subjugation of any sentient beings will to his own without that being's deliberate submission. Likewise, he cannot make the same kind of deal with the same person he has done before. Moreover, Mephisto cannot directly affect beings from other realities, as he cannot harm the Norman Osborn from Earth-44145 by claiming he was outside his jurisdiction. He is also incapable of reading the thoughts of any sentient being. Mephisto's powers are linked with his extra-dimensional realm and his powers rapidly decrease the longer he is away from his realm. As a result, he typically uses or manipulates others into performing whatever plan he has in mind. Also, despite continuously trying to get any noble soul to his realm and possession, he must need to corrupt them first, or otherwise, he himself will be, ironically, injured in the process. In fact, in the event that Mephisto is usurped from his position, incapacitated or even destroyed to the point of being unable to reestablish, all his mystical actions, including his deals with their victims, began to crumble and fall apart. This also seems to apply to their victims, as their agreements will also lose effect and break if their deaths were not predetermined in terms of the pact they established with Mephisto.
