Origin: Marvel Comics
Classification: Human enhanced by chemical serum (a much more powerful version of the one used on Captain America) superhero
Age: In his 30s or 40s
Powers and Abilities: Super strength, super leaping, super durability, invulnerability, super resistance to injury, super endurance, super speed, flight, dimensional travel, super reflexes, super agility, immortality, longevity, super immune system, regenerative healing factor, super hearing, super sight, aura vision, doesn't need sleep, air, food or water, immunity to viruses, telepathy (see Other for feats), telekinesis (his mind holds his physical powers together), energy manipulation (like drawing on ambient energy, calming the Savage Hulk with his aura and sometimes displaying energy physiology), forcefields, constructs, energy projection and omnidirectional attacks, light, darkness, fire, wind and weather manipulation, thunderclaps, invisibility, intangibility, shapeshifting, transmutation (see Other for matter manipulation feats), can devour souls, can empower others, his body's atoms are an instant ahead of the current timeline (and their nature was unknown to Molecule Man relative to all the molecules he had experienced), survives in space
Destructive Capability: Solar System level+ (energy output feats include atomizing Absorbing Man and releasing planetbusting power against Genis-Vell while holding back)
Range: Stellar+ w/telepathy and energy attacks, but only melee range (human form, w/shapeshifting can extend himself for hundreds of kilometers)
Weaknesses: He's mentally unstable and a relapsing drug addict, prone to be manipulated by the cunning w/knowledge of him (like hacking CLOC to overwhelm and deceive him with false disaster information, which gave him a guilt trip and freaked him out into inaction for hours). He becomes weaker if his mental state wavers/loses confidence (similar to Gladiator, the Void persona tends to be more confident). Dumping him in the Negative Zone (a dimension where all matter is negatively charged) massively depowers the Sentry (not the Void persona, it's unknown if this still affects him). He currently lacks the experience and finesse with his powers that Molecule Man has
Lifting Strength: At least 1 septillion (1,000,000,000,000,000,000,000,000) tons, but a few of his feats are, flying right past the Crimson Bands of Cytorrak spell of Dr. Doom, etc.
Striking Strength: At least 1 yottatonne (1,000,000,000,000,000,000,000,000 tons of force), but a few of his feats are, breaking Dr. Doom's full-strength forcefields and armor, making the Void keep many of Earth's heroes (Avengers including Thor, as well as the Fantastic Four, X-Men and others) and villains busy with his tendrils, including breaking the Hulk's bones, while engaging the Sentry at the same time (basically Robert Reynolds fighting with himself), before his attacks started getting stronger, making the Void damage a constantly boosted Dr. Strange forcefield also propped by Iron Man and Invisible Woman (while ignoring the attacks of Black Bolt and his Inhumans, Namor, the Human Torch, the Thing, multiple X-Men, Avengers and others), overpowering Ares and ripping him in half, overpowering Thor, then bringing down Asgard, overpowering Terrax the Tamer, breaking his hand and planetbusting axe, etc.
Durability: Multi - stellar level+, but a few of his feats are, tanking an angry Savage Hulk attack, momentarily resisting an escaping Cosmic Cube's energies (doubles as a strength feat, even an incomplete Cube lacking proper shape can emit cosmic radiation that affects matter on the molecular level), resisting multiple punches from World War Hulk, resisting fighting the Collective, which was powered by the energies of millions of Earth mutants (including Xorn and Magneto) and had taken down the Herald level Binary Ms. Marvel moments before, resisting multiple attacks from Thor, during his fight against Genis-Vell in the Microverse (where planets are subatomic-sized) that released enough power to be visible in the regular universe, emerging from it relatively unscathed,, etc., and if his durability is breached, the Sentry's regeneration makes him extremely hard to kill, a few of his feats for this are, receiving a Kree gun headshot (getting up and regenerating when he felt like it), getting magically blown up (reappearing from it whole), throwing himself into the Sun and regenerating his burned to the bones body on the spot (despite his suicidal mental state), molecule Man's repeated attempts to kill him (from which he reformed in short notice), etc.
Stamina: Limitless, before realizing the nature of his powers and when not unleashing his full power he only lost his superpowered state after an extended brawl against World War Hulk while also expending enough energy for Hulk to reverse into his human Bruce Banner form despite his anger, the current Sentry can keep fighting with no power loss even after having his body destroyed multiple times
Speed: Massively hypersonic (solves disasters all over the world at superspeed) to FTL (exact level unknown, has flown to the Sun in a short time and crossed interstellar distances in the past)
Intelligence: Technological genius (the Sentry helped to design his Watchtower along with Reed Richards and built a robotic dog stronger than the Thing and Wendigo, the Void built or created his own twisted parody of the Watchtower and CLOC, including drones capable of hurting the Sentry) and mentor to heroes in the past, but can be impaired by his psychoses and insecurities
Standard Equipment: CLOC sentient computer system that feeds him information from all over the world and prioritizes what emergencies he should handle
- Infinitendrils: Black tendrils he can sprout from his body or from dark clouds he creates with his molecular powers. They can attack physically, make stuff explode on contact or phase into people to take control of their minds, inflict traumatic visions of their past, present and future or eat their souls.
- Sun Dumping: Sentry grabs and throws his enemy into the Sun.
- Thunderclap: Sentry is capable of creating tremendous concussive force by simply clapping his hands together.
- Void: A cosmic monster created by Robert Reynolds with his molecular powers after he drank the Sentry serum, to embody the negative parts of him that he can't control and were accentuated by the serum. In the past he materialized on his own as a separate entity that balanced the Sentry's heroics with evil, or was directly created when Reynolds believed him to be around. He lost power and faded when Reynolds willed it after achieving mental stability and dominion of himself or when Sentry mindwiped himself and everybody else after the Void was becoming too independent and powerful, also being defeated by Sentry when their balance was broken (after the Void killed more people than the Sentry saved). But the Void always returned on his own as long as Sentry existed, in fact every seen incarnation of the character has displayed varying degrees of the Void in order to be able to act against his enemies even when performing heroics. During the events of Secret Invasion the Sentry and the Void personas merged again, with the Void starting to assert dominance throughout the events of Dark Reign (especially manifesting after Sentry suffered mental trauma or severe physical damage), culminating with the Void getting released during the events of Siege. It was also lately shown that the Void and the Sentry's power is the Judeo-Christian God, or that Robert Reynolds became empowered by an equivalent force.
