Well... Here it is, The Sentry Vs Superman. And let me tell you, it was hard to come to a decision on this one. They both have astronomical power and both are technically limitless in their power... So I have went with the one I feel would win and will give a reason for it after the battle. Enjoy!
The two titans levitated apart from each other, just above the earth. One wearing a blue suit with red boots and cape with a red 'S' on his chest. Superman. The other, a blond man wearing a golden yellow suit with a blue belt around his waist with a shining 'S' on it. The Sentry. They glared at each other with intensity.
Fight!
The Sentry charged at Superman and punched him in the jaw and followed that up with a knee to the stomach. He tried to Axe-Handle Superman down, but Superman dodged and blasted Sentry with his Heat Vision, Sentry was sent tumbling back but caught himself in time to receive a earth shattering right hand from Superman across the face, sending him flying even further. Superman kept up this barrage of punches and finished it off with an axe-handle downward, sending Sentry crashing into the moon. Superman flew down to the newly created crater and connected with a thundering punch to Sentry's abdomen, causing a massive shockwave. He kept punching Sentry further into the ground, making the crater bigger and bigger. Shockwaves echoed across the moon before abruptly stopping as Sentry caught the fists and blasted Superman off of him into the sky.
Sentry flew up and faced Superman, "You hit hard." Sentry said with a smirk. Superman crossed his arms, "So do you. I actually felt those." Superman replied. Sentry furrowed his brow at the comment and charged at Superman but disappeared suddenly but Superman still keeled over from a strike to the solar plexus. He was then kicked down by an invisible Sentry. Sentry reappeared, "Did that hurt?" Sentry asked confidently. Superman smirked, "It stung." He replied. Superman fired his Heat Vision at Sentry again but missed as Sentry sidestepped it and rushed Superman, he went to inch him but Superman caught the fist and threw Sentry far into space. Sentry caught himself just above Venus. "Ok... He is good." Sentry muttered to himself, "Thank you." Superman said as he floated toward him. Superman charged at him and kneed Sentry in the stomach and then punched him down into Venus, a huge explosion occurring from the impact.
Superman flew downward onto the planet and saw Sentry clearing standing, more pissed than hurt. "You're tough, but I must end this." Superman said. Sentry smirked as energy surrounded him, "You can try, Boy Scout." Sentry stated. Sentry blasted at Superman multiple times, each blast was that of a planet busting explosion. Superman tanked each blast but was suddenly dragged down by a construct made by Sentry. Sentry uppercutted Superman and then elbowed him in the face, cutting Superman's lip, Sentry then blasted Superman off of the planet and sent him flying. Unbeknownst to Sentry, they were getting closer to the sun. Superman had regained his composure and floated in front of the sun.
Superman turned around as he heard an almighty shout coming from Sentry as he tackled Superman into the sun. Sentry was repeatedly punching Superman as they contented in the star. Superman just blasted Sentry with his heat vision, fully engulfing him, "You made a big mistake taking me here." Superman remarked, but Sentry just stood there, unmoved by the heat vision. Superman used his microscopic vision and saw that Sentry was also absorbing the solar radiation. "Oh.." This dawned on Superman. Sentry then kneed Superman in the face and blasted him down. Superman unleashed more heat vision on Sentry, more powerful than the last and began to push Sentry back. He then rushed Sentry and punched him multiple times in the abdomen and face, cutting Sentry's lip and busting his nose. Superman tried another strike but Sentry blocked it and trapped both of Superman's arms. "Say goodbye to your power source!" Sentry shouted as he began to unleash energy from his body and it engulfed them both as the sun exploded around them, but Sentry wasn't finished as he amped up the power even more to that of hundreds of Supernovas.
When the dust settled Superman was groggy and had cuts, bruises and broken bones. His suit of shredded and he panted. Sentry stood with nothing more than a cut on his head that was bleeding. Sentry slowly floated toward Superman, "This is over." Sentry stated. Superman's skin began to glow gold as he oozed with energy. "Yes... For you." Superman replied. Superman exploded his energy outward with his Super Flare ability. Superman unleashed all his reserve solar energy, every lost drop of solar energy he had in his body to try and finish off Sentry. The explosion settled, "It's over n- Agh!" Superman was interrupted by Sentry clutching him by the throat. "Yes. It is over now." Sentry stated as he broke Superman's neck and left him to float in space, dead.
KO!
Pitchforks down DC fans. Hold your horses, calm thy tits. Before the rage let me explain the reasons for Sentry's victory.
1: Sentry is similar to Superman in many ways, but unlike Superman Sentry can absorb any form of energy he wants. Matter, Solar, etc. He is enemies with the Absorbing Man, who has that very same ability. So he can easily deal with and counter Superman's Solar absorption.
2: Sentry is far more durable than Superman. He has literally come back from nothing. Superman has not.
3: Now for those of you who are going to give the World War Hulk argument, Sentry before and since then has never 'burnt out'. That was completely needed for the plot. And let's not forget, World War Hulk was the Hulk that was sin,in the entire eastern seaboard of America by simply walking! And it's stated if he kept going he'd have broken the earth! So this argument is invalid.
4: Even if this argument was valid, since then Sentry has fought more powerful foes for longer, example; Molecule Man! So again not happening.
5: Finally, Sentry has been stated to be immortal! He has matter manipulation, energy absorption and magical transmutation among other abilities. Any way you slice it, Sentry is winning.
The winner is: The Sentry!
