Wonder Woman, as strong as she is, has been challenged by Superman's incredible strength quite a few times. This would mean that she also would have no chance against The Sentry. He's just too fast and strong for her to deal with.
Sentry would easily win. Sentry is leagues above Supergirl. He's stronger, more durable, and faster than her, he also has molecule manipulation, light projection, various psionic abilities, a very powerful healing factor and he can resurrect people.
The Sentry is one of the most powerful heroes in the Marvel Universe, and may be capable of destroying DC's Superman. Superman is arguably the one superhero that all so many others have been derived from or influenced by.
Highlights. Wonder Woman's strength and powers are impressive, but she has been defeated by surprising opponents. Batwoman managed to beat Wonder Woman and nearly kill her using her combat skills and the lasso of truth. Swamp Thing easily defeated Wonder Woman without even needing to attack her, leaving her helpless.
Even with her fighting knowledge, Hulk's raw power alone is likely far too much for her to handle. Furthermore, Hulk only grows stronger as his rage increases. In a prolonged fight with Wonder Woman, he is very likely to grow ever stronger, eventually being able to completely overpower her.
Litterally. Sentry is one of the most powerful non-cosmic entity characters that exists, along with Powerhouse. Even with 2 or 3 stones Thanos might lose.
It's incredible that even after such an intense fight with the Sentry, the Hulk had the capacity to nearly destroy the world. Ultimately, it was a close match, but it seems that the Hulk won out in the end.
Deadpool knows all too well about the dangers of an internal battle and could take advantage of that instability. If Sentry and Deadpool were to face off in one on one combat, Sentry would eventually lose, as he has done in the comics multiple times.
While Sentry has multiple wins over Thor, every single one came from a version more powerful than Golden Sentry while Thor has stayed his regular self or worse (see golden thor). By feats and fights, Thor would beat Golden Sentry. But he would lose to Voided-Out Sentry, All-New/Perfect Sentry, and Death Seed Sentry.
Given that Sentry is often described as having the power of a million exploding suns, it's easy to see why he handily destroys Black Adam. Being one of the most overpowered superheroes of all time, Sentry has more than enough power to defeat Black Adam in seconds.
No odin is more powerful than Sentry Odin can destory a galaxy and create one he expelled mephisto from his own realm who is completely powerful there and he evicted him from there.
Sentry is someone who would find Goku a challenge that he could easily overcome because his strength is almost equal to that of the Saiyan, with the added benefit of his various other powers like time manipulation, matter manipulation, and superhuman stamina.
The Sentry may get through Darkseid's legions. He's very powerful. However, if he came face to face with Darkseid, he just couldn't defeat him. Darkseid is more powerful than anything the Sentry has ever faced and even if the Void manifested, Darkseid would still win.
The Sentry, Marvel's version of Superman, has an array of superpowers and no clear weakness like kryptonite. However, he has been defeated by stronger opponents. Absorbing Man used the power of the Cosmic Cube to overwhelm the Sentry, fracturing his mind and securing a victory.
The Sentry's physical power is unmatched, but Cosmic Ghost Rider would still give him a hard fight. It's almost certain that the stress of the battle would bring the Void out, which would be the end for the CGR. The Sentry is powerful, but he's not as vicious as the Void, who would go all out to destroy Castle.
It is true that, during Siege, Sentry rips Hercules' fellow Olympian god, Ares, in half, but that doesn't mean he could do the same with the Prince of Power. In terms of raw strength, Hercules is at least Sentry's equal, as he proved when he easily blocked his punch during the battle.
Both characters can potentially give each other a beating, but both can take one as well. While Sentry and Superman have several similar abilities, the main factor in this situation is control. The Man of Steel has far more willpower than Sentry, constantly triumphing over his weaknesses.
It's no surprise Sentry took on Galactus and survived the ordeal. After all, he was originally created to be the most overpowered and strong superhero in existence.
Sentry's physical strength is on a completely different level though. He can rip an Olympian God in half with ease, so Captain America's human body would not be an issue.
While Doom has handled more powerful beings, he was ready for them. The Sentry was an unknown for Doom and he had no plan for dealing with him. Doom was too smart to run in without a plan, which meant he's never defeated the Sentry.
Wonder Woman is around the same level as Loki when it comes to strength, but she's easily the better fighter. Loki could spin some magical web around her, though Wonder Woman only needs to take the battle to the skies or land a well-timed whip of the Lasso of Truth to incapacitate Loki.
Wonder Woman has faced down lots of powerful opponents in her day but on her own, she's never faced anyone like Cosmic Ghost Rider. While her skills have helped her triumph over foes much more powerful than her, Cosmic Ghost Rider is just way too much for her.
