Out of all the heroes and villains that Marvel has introduced in the past twenty years, Sentry has arguably left the biggest dent. Commonly referred to as Marvel's Superman -- albeit, a mentally unstable version -- fans know that whenever Sentry pops up in a story, the tide will change for better or worse. Since his debut in 2000's Sentry (Vol. 1) #1, Sentry and his evil alter ego, the Void, have played pivotal roles in several blockbuster event comics. Recently, the already ultra-powerful Sentry has gained an upgrade as a consequence of finally integrating the Void into his psyche. With Sentry poised to be more impactful than ever, we've decided to take a look back at his 20 most overpowered moments.

Although Sentry is often reductively referred to as a Superman rip-off, the comparison really doesn't do Marvel's golden-haired god justice. To say that Sentry is complex would be a vast understatement. Psychologically, he's split between his benevolent personality and the Void -- a malignant entity with an insatiable desire for destruction. As for his powers, Sentry's abilities appear to be virtually limitless in scope and scale. There's no telling what the limits of his strength or speed are, and every time he emerges, he seems to bring with him an all-new godly ability. With all of that power, it makes sense that Sentry would've made such an impact just within his first decade as Marvel character. Sentry's already casually taken out A-list heroes and villains, fought Hulk to a standstill, and taken a nuclear missile to the face. Here's our ranking of Sentry's 20 most OP moments.

20 SHATTERS TERRAX THE TAMER'S AX

Some of Sentry's greatest feats look totally effortless. He'll often casually knock out A-list characters or brush off an attack that would've put lesser heroes in the grave. A good example of Sentry's nonchalant godliness comes from Sentry (Vol. 2) #1. In the issue, Sentry goes head to head against Terrax the Tamer, one of Galactus' heralds.

As a herald of Galactus, Terrax is imbued with the power cosmic, but more destructive than that is the cosmic ax that he carries, capable of ripping up Galactus' own ship. However, none of this matters to someone like Sentry. Sentry easily subdues Terrax and snaps the cosmic ax as if it were a pencil.

19 TOSSES SHE-HULK TO NEW JERSEY

One of Sentry's most impressive feats of strength came in Savage She-Hulk (Vol. 2) #2. Sentry interferes in a conflict between the original She-Hulk (Jennifer Walters) and the new She-Hulk, Lyra, the alternate reality daughter of the Hulk. Lyra comes to Earth-616 in search of the planet's greatest hero.

Sentry, having heard of Lyra's mission and thinking that he is the one she seeks, intercedes on her behalf by tossing Walters from New York to New Jersey. Despite how casually Sentry throws She-Hulk, the act was no small feat. Unfortunately for Sentry, Lyra wasn't looking for him but for Norman Osborn.

18 SHARES POWERS WITH SCOUT

Among Sentry's wide variety of powers is the unique ability to share his powers with others. In fact, he used this capacity to create his sidekick, Scout. Before meeting Sentry, Billy Turner had been an ordinary teenage boy who wanted to do good wherever he could. Sentry bestowed a portion of his power onto Billy, thus transforming him into the superhero known as Scout.

Sentry would later do the same thing for his dog, Normie. Sharing his powers with Normie, he transformed the dog into a type of four-legged sidekick, much like Superman's dog Krypto (as if there weren't enough comparisons between Superman and Sentry).

17 INFECTS AVENGERS WITH ZOMBIE VIRUS

An alternate reality version of Sentry is partly responsible for the entire Marvel Zombieverse. Sentry was infected with the zombie virus by the Hulk and eventually became the last zombie in his reality. Uatu the Watcher seized the opportunity to contain the zombie outbreak by sending Sentry back in time, thus creating a segment of time that enclosed the zombie virus.

Once sent back, the zombified Sentry inevitably ran into the Avengers, who he quickly infected. The time paradox set off the events of the Marvel Zombieverse, but also managed to keep the virus from spiraling out of control. Confusing, right?

16 TAKES APART CARNAGE

The first story arc of New Avengers (Vol. 1) saw the new generation of Avengers come together by accident while trying to contain a supervillain breakout from a high-security prison. Captain America, Daredevil, Spider-Man, Wolverine and others all happened to assemble in response to the crisis.

However, of particular surprise, was the appearance of Sentry, who'd been voluntarily held in the prison. When Daredevil's friend Foggy Nelson was threatened by Carnage, Sentry stepped out of the shadows to take on the evil symbiote. Sentry took hold of Carnage and flew it into outer space where he took it apart with ease.

15 TAKES OUT LOKI

Siege (Vol. 1) represented the climax of Marvel's Dark Reign, but also the payoff to several years of Sentry stories. Leading up to the event, Sentry had been led by Norman Osborn to believe that the Void never existed, which would only ensure that the Void would return stronger and more uncontrollable than ever.

The Void made its return during "Siege" and brought its bloodlust with it. It took out several major characters, including the God of Mischief, Loki. Loki had been empowering the Avengers with the Norn Stones, making him a high-priority target for Sentry's evil alter ego.

14 THE VOID BEATS YELENA BELOVA

Yelena Belova, a special agent who formerly operated under the alias of Black Widow, acquired the abilities of the Super-Adaptoid in her quest to bring down the New Avengers. Belova immediately used her Adaptoid abilities to absorb the powers of the most powerful Avenger -- the Sentry.

However, her plan backfired as she also absorbed the Void. The Void, let loose at last, turned on Belova, overwhelming her despite her access to all of the Avengers' powers. To this day, this remains one of the only instances that the Void inadvertently worked for Sentry. Most of the time, the Void is a chaotic entity, set on destruction at all costs.

13 MAKES QUICK WORK OF ATTUMA

Attuma is a classic Namor antagonist, having repeatedly plotted to overtake Atlantis throughout the years. However, no matter how many times he'd been beaten by Namor, Attuma always found a way to come back as more of a menace than ever. Attuma made a fatal mistake when he took aim on New York City, home of the New Avengers.

In Sentry (Vol. 2) #1, Attuma led his legions of octo-mechs into an all-out assault on the Big Apple. A battle ensued when Attuma and his forces were thwarted by the New Avengers, but the conflict didn't end until Sentry arrived on the scene. Sentry immediately ended the invasion by wiping out the octo-mechs and taking out Attuma.

12 HOLDS OFF THE ORIGINAL AVENGERS

The original Sentry mini-series retconned Sentry into the beginning of the age of superheroes, revealing to us that he'd been around during '60s era Marvel. The miniseries showed Sentry as a popular hero in Marvel's early years, teaming up with the young Spider-Man and nascent superteams like the Fantastic Four.

It also explored the emergence of Sentry's alter ego, the Void, and how much damage it could do. One such instance of the Void's incredible power came when it faced off against the classic Avengers. The Void used its tremendous power to lock the Avengers in a kind of stasis that only relented when Sentry's benevolent personality reemerged.

11 BREAKS FREE OF DR. STRANGE'S SIMULATED REALITY

Doctor Strange and Sentry have a storied history. After the Void first emerged in the early years of Marvel's superhero age, Dr. Strange helped Sentry to wipe the mind's the Earth's populace and to help Sentry to forget about his powers. Years later, when Sentry would return and team up with modern heroes, Strange worried about Sentry's mental stability and the possible reemergence of the Void.

When Sentry was on a mission to discover the truth about his past and of the Void, he looked to Strange for information. Afraid that the Void was on the brink of returning, Strange decided to confine Sentry in a simulated reality. However, even the Sorcerer Supreme's grand illusion wasn't enough to contain Sentry.

10 ENDS ARES

Siege (Vol. 1) #2 featured one of the most memorable images in the history of Marvel Comics. The story saw Ares, Sentry's teammate on the Dark Avengers, betray the team during Norman Osborn's attack on Asgard. The God of War charged Osborn and Sentry intervened. At the time, Sentry was possessed by his evil alter ego, the Void, ensuring that he'd show no mercy against whoever he targeted.

Sure enough, Sentry didn't waste any time ripping Ares in half. For a mainstream Marvel comic, the image was incredibly suprising. It also reinforced the fact that Sentry spelled doom for whoever stepped into his path.

9 CATCHES THE S.H.I.E.L.D. HELICARRIER

Sentry has had two notable run-ins with the S.H.I.E.L.D. Helicarrier. The first came during Mighty Avengers (Vol. 1) #3 when Ultron sent the Hellicarrier onto a collision course with Manhattan. Sentry bolted to the scene and was able to guide the massive aircraft to a smooth landing.

The second time that Sentry ran into the Helicarrier was during Siege (Vol. 1). Sentry had been possessed by the Void and was wreaking havoc on the Avengers in Asgard. Running out of options against the ultra-powerful Void, Iron Man decided to direct the Helicarrier at the evil entity. Still, after being hit with the Helicarrier, the Void was only temporarily incapacitated.

8 THROWS THE VOID INTO THE SUN

Sentry's struggle with the Void came to a head during Sentry (Vol. 2). The miniseries followed Sentry as he sought out the truth of his origin and the nature of the Void. Sentry discovered that he received his powers as a result of an extremely potent Super Soldier serum and that the Void was a real entity that was an expression of Sentry's darker emotions.

The Void explained that it was needed to balance out the good deeds that Sentry did. Sentry refused to believe that he needed the Void, leading to a battle between the two in the final issue of the miniseries. The epic conflict concluded with Sentry taking his evil half and disposing it into the sun.

7 HELPS HYPNOTIZE THE EARTH'S POPULACE

The original Sentry miniseries revealed that Sentry had been one of Marvel's original superheroes. It's just that the populace of Earth-616 couldn't remember him because all of their minds had been wiped. The Void had grown increasingly out of control and was responsible for an unfathomable tragedy in Manhatten.

Knowing that the Void was the manifestation of the repressed aspects of his powers, Sentry decided the best way to get rid of the Void was for everyone, including himself, to forget the Sentry ever existed. Thus, Sentry worked with Doctor Strange and Reed Richards to hypnotize the Earth's populace into forgetting his and his evil alter ego's existence.

6 ENDS WORLD WAR HULK

Hulk has rarely been more dangerous than he was during World War Hulk (Vol. 1). The story featured the Green Goliath's long-awaited return to Earth and his insatiable desire for revenge against the superheroes who'd exiled him. On his warpath, Hulk took out the entire X-Men, the Avengers, Doc Samson, Juggernaut, and the Fantastic Four.

Toward the end of the miniseries, Hulk finally faced off against someone who was an even match -- the Sentry. The typically restrained Sentry let loose against the green goliath, and the two battled to a standstill. The clash of the titans concluded with both of them collapsing and returning to their depowered forms.

5 BRIEFLY CONTAINS THE COSMIC CUBE

The Cosmic Cube is one of the most powerful artifacts in Marvel lore. Ever since the Cosmic Cube was introduced in Tales of Suspense (Vol. 1) #79, supervillains have been vying for its possession, doing whatever it takes to acquire its power to manipulate matter and energy to a virtually boundless degree.

With that being said, when activated, it seems safe to say that the Cosmic Cube's energy is impossible to be contained for long. However, in Sentry/Fantastic Four (Vol. 1) #1, Sentry attempts the impossible and is able to at least temporarily contain the tremendous energy of the Cosmic Cube.

4 BRUSHES OFF A NUKE

Even in Sentry's earliest days, he was unlike any Marvel hero around. Sentry/X-Men (Vol. 1) #1 displays Sentry's invulnerability in a flashy way. The issue features a mad tyrant launching multiple nuclear missiles. Sentry intervenes, disabling all of the nukes and then taking one at point-blank range.

The X-Men, of course, are convinced that their friend has perished, but Sentry pops up at the issue's end with what only looks like a flesh wound. While undeniably impressive at the time, over the years, Sentry would repeatedly top himself, each time seeming less like a mere superhero and more like a god.

3 RESURRECTS HIS WIFE

Many of Sentry's most OP moments transcend feats of mere superheroes and enter into a godly territory. There's no better example of Sentry's godly and mysterious level of power than when he resurrects his wife, Lindy. Sentry discovers Lindy's limp body in the Watchtower, her life having been taken by Ultron.

However, upon being touched by Sentry, new life floods into Lindy's body. Sentry's ability to bring his wife back to life is never adequately explained. The hero himself didn't understand what had happened and knew that the ability to resurrect others was well beyond his control. We'll just chalk it up to Sentry being Sentry.

2 CAN DO ANYTHING A MOLECULE MAN CAN

Shortly after Sentry joined Norman Osborn's Dark Avengers, he began to display a suprising new ability. During the first story arc of Dark Avengers (Vol. 1), the imposter Avengers battle Morgan le Fay, a sorceress capable of manipulating reality. Sentry appears to be bested by Morgan le Fay early on, but he mysteriously returns out of a flashing light at the end of the story.

A few issues later, Sentry goes head-to-head with Molecule Man, seeming to have finally met his match. In fact, Molecule Man decimates Sentry yet, again, Sentry reforms out of nothing. Like Molecule Man, Sentry had found a way to rebuild himself by way of molecular manipulation.

1 SPOKE THROUGH PAUL JENKINS

How powerful is Sentry? On some occasions, it's been said that his abilities are limitless. However, the best example of Sentry's godliness is revealed to us in New Avengers (Vol. 1) #10. The issue reveals that Sentry was responsible for (real) writer Paul Jenkins' creation of the original Sentry (Vol. 1) miniseries.

We learn that Sentry stored his memories into Jenkins' subconscious, inspiring him to tell Sentry's story. With Sentry's repressed memories expressed through the comic book medium, he was able to gain an upper hand over his malignant alter ego, the Void. Sentry is one of the few Marvel characters to have broken through the fourth wall in such a mind-bending way.
