Summary
Introduced as one of thestrongest characters in the MCU inThunderbolts*, Sentry wields near‑divine powers, as he measured himself in one of the film’s most emblematic scenes after defeating the team of heroes. To make matters worse, he carries a dark side, Void, which triggers an inner conflict that stands among his few vulnerabilities.
Considering not only current MCU characters but also those in the comics who may reach future films, the figures able to defeat Sentry/Void need more than immeasurable power; they require intelligence and strategy to confront him. If such clashes happen, given the scale of his abilities, these fights could rank among the most epic ever seen in the MCU.
10Hulk
One Of The Strongest Characters Would Have To Rely On His Intellect To Face Sentry
With Sentry’s weaknesses and limits still undefined, Hulk could stand as a foe robust enough to bring him down in a direct showdown. By methodically exploiting Sentry’s emotional instability, scientist Bruce Banner might manipulate him or trigger a catastrophic mental collapse, weakening the hero severely and giving Hulk,at his peak as theWorld Breaker Hulk, the decisive opening to end the fight.
Sentry avoids direct combat in the comics for fear of unleashing Void, a trait explored inThunderbolts*, so Bruce could exploit that caution to make him hold back and open a lane for a full‑force Hulk assault. Even so, technological support or allied assistance would likely be required to secure Sentry’s defeat, a scenario that remains plausible given Hulk’s wide network of partnerships.
9America Chavez
One Of The Youngest Heroines Could Defeat The Sentry/Void Threat
Although the battle would be demanding, America Chavez ranks among the rare heroes who can overcome Sentry/Void thanks to her broad multiversal abilities. By opening stable dimensional portals at will, America could reach countless alternate realities where Sentry never fell to Void or was already defeated, gathering crucial strategic knowledge and rare artifacts able to end the conflict decisively once and for all.
The young heroine could also travel through time or to alternate timelines to prevent the serum’s creation or stop Robert from ingesting it, neutralizing him before he becomes a threat to the world. America could even open a gate to a dimension where Sentry’s powers fail,something she nearly did to Wanda MaximoffinDoctor Strange in the Multiverse of Madness.
8Captain Marvel
With Her Absorption Abilities, The Heroine Could Confront Him Directly
Having faced Thanos head‑on more than once, Captain Marvelalready proved she can match cosmicheavyweights, making her a major threat to Sentry in any direct confrontation. Carol can absorb and redirect vast quantities of cosmic, even nuclear, energy; should she gather power equivalent to an interstellar explosion, one precise, focused strike could neutralize Sentry/Void, even if only for a brief tactical window.
Carol’s victory may involve more than brute force; she could compel him to face his own destructive acts, as in theDark Avengerscomic arc. Thanks to her steady emotions, the heroine could steer him toward surrender or even sacrifice, drawing on her experience with extreme power and authority to deliver an ending ultimately suited to the MCU’s more friendly tone.
7Thor
Former Strongest Avenger, He Could Confront Sentry With His Divine Strength
Despite his reputation for sheer might, Thor would not defeat Sentry/Void with brute force alone; instead he would weave strength, tactical insight, and ancient magic into a single assault. Though still unseen in the MCU, the God of Thunder could channel the Odinforce, a vast royal Asgardian energy, allowing him to battle Sentry as an equal, a development easily justified as an inheritance or as a gift tied to Asgard’s ongoing reconstruction.
Wielding Stormbreaker, the hero could absorb Void, seal the entity within the axe, or ferry it to an isolated dimension such as the Quantum Realm, sacrificing himself in a dramatic MCU climax. In a direct clash, Thor could twin Stormbreaker with Mjolnir to redirect energy and soak up Sentry’s strikes, presenting one of the few workable methods to harm him.
6Loki
With Unlimited Powers, The God Of Time Could Pose A Huge Threat To Sentry
In his most extreme state as a god of time,Loki could be among the scarce characterstruly capable of defeating Sentry/Void on his own. By commandeering the timeline, Loki might stop or slow time to nullify Sentry’s attacks, banish him to a branch where he lacks powers, or trap him inside a perpetual temporal loop, mirroring the tactic Strange used against Dormammu.
One of Sentry’s greatest problems is his dark counterpart, Void, which Loki could separate by creating a rupture point where Sentry and Void split, or imprison one part in a branched timeline, allowing him to defeat the other with ease. This would not be Loki’s first clash with a powerful threat; he already overcame Kang at the end of his self‑titled series.
5Doctor Strange
The Sorcerer Supreme Ranks Among The Characters Capable Of Defeating Sentry/Void
As one of Marvel’s most powerful magic users, Doctor Strange could confront Sentry/Void head‑on. By opening portals to the Mirror Dimension, the wizard might imprison Sentry outside the primary reality or perform banishment rituals that split Void from Robert’s body, a maneuver that would weaken the cosmic powerhouse and sharply improve the probability of ever successfully finally bringing him down.
Strange could exploit Robert’s mental instability, entering his mind through illusion spells and astral projection and forcing him to face his dark half, thereby sapping his strength. That psychological breach would simplify any subsequent physical confrontation, with or without allies, and Stephen’s long‑honed expertise has already toppledformidable entities such as Dormammuwithin the mystic arts over countless prior battles.
4Scarlet Witch
As One Of Marvel’s Most Powerful Characters, She Could Defeat Sentry
Given the destructive power wielded by both combatants,a potential clash between Scarlet Witchand Sentry/Void would stand among the MCU’s most spectacular showdowns. With several abilities already established onscreen, Wanda Maximoff could exploit his mental fragility and make him confront Void, rendering the hybrid vulnerable and volatile; she could also deploy spells or artifacts to banish, erase, or seal Sentry entirely.
As one of the MCU’s mightiest figures, Wanda could employ dreamwalking, inhabiting the bodies of her alternate versions and using that technique to ambush Sentry from one reality to another. Through such leaps she could trap him in a circuit of universes or cast him into a hostile cosmos from which escape is impossible, neutralizing the threat without relying on conventional force.
3Black Widow
Black Widow Proved Essential To His Defeat In Thunderbolts*
Given the relationship developed inThunderbolts*, Black Widow emerges as one of the characters most likely to subdue Sentry/Void during the mission at the core of the plot. Although Yelena Belova, a Red Room‑trained operative, cannot confront the cosmic figure in direct battle, as the film already showed, she reached him emotionally and pressed him to repress his darker half, buying crucial time for a coordinated strike.
Their connection, forged from the film’s opening moments, allowed Yelena to reach him even within the darkest recesses of his mind, underscoring her unique influence over the MCU’s most powerful being. By leveraging that bond, Black Widow persuaded Bob to suppress Void; she could likewise force Sentry to retreat or target his emotions to finish him, demonstrating how empathy can overcome raw strength.
2Phoenix
The Phoenix Force Ensures The Character Stands As A Worthy Opponent For Sentry
With the X‑Men returning to the MCU, Phoenix (Jean Grey) could match Sentry/Void blow for blow in open combat. The Phoenix Force, counted among Marvel’s most potent entities, could destabilize the Sentry/Void equilibrium, compelling one persona to consume the other and even erasing his plane of existencethrough Dark Phoenix levels of poweron a cosmic scale.
As one of Marvel’s most powerful telepaths, Jean Grey could probe the hero’s traumas and fears at their deepest layers, dominating him psychically and driving him toward collapse. Her empathy might convince him to sacrifice himself or suppress his powers; alternatively, drawing on her Phoenix experience, she could force a separation and isolate Void before it utterly ravages the universe.
1Doctor Doom
The Character Most Capable Of Defeating Sentry
Confirmed as the marquee villain of Marvel’s Phase 6,Doctor Doomranks as the individual most likely to utterly defeat Sentry/Void in direct combat. A duel between these titans would eclipse prior MCU battles in scale, and with peerless intellect blended seamlessly with sorcery, Doom could craft a layered plan spanning time and dimensions, ensuring victory while entire worlds watched.
The villain could exploit Sentry/Void’s mental weaknesses, combining manipulation with magical illusions to awaken the dark side and then simultaneously contain it with arcane artifacts or technomagic. Renowned for preparation, Doom might unleash advanced technology or even harness Void itself, extracting its energy or bending the entity into a weapon that furthers his grand designs across multiple realities with ruthless precision.
