Recently in Thor: Ragnarok many people fell in love with MCU Korg, but I wanted to give some respect to comic Korg, the most powerful of Hulk's Warbound.
Korg is a member of the Kronan race and was formed from lava on the planet Ria. He was stationed on Saturn to help invade Earth, but when he attempted to invade Earth with his brother Margus he was faced with The Mighty Thor. Thor destroyed the Kronan's robot and busted out of their cage. Thinking that all of the human race was as powerful as Thor the Kronans tried to flee back to their home world in shame. On their way back to Ria the Kronans fell through a wormhole onto the planet Sakaar. The Kronans were forced to fight in the Red King's arena, but Korg's brother, Margus resisted the control disks and lost his mind. Korg was forced to train in the Maw with other gladiators. Korg fought the Hulk when they met in the Maw, but after they were both among the 7 survivors joined his Warbound. While training in the Maw Korg was forced to fight his now insane brother alongside Hulk. Korg fighting against his brother truly solidified his place as probably the most powerful member of the Hulk's Warbound.
Korg has some pretty good strength feats though by far his best take place on Sakaar
In the scans above Korg Holds up a tall building with Hercules, Catches an angry Hulk's punch, easily pulls a tree out of the ground, and takes down a spaceship by throwing a large rock at it
Korg's best lifting strength feat however is holding "The very mountains on his back" for a couple of seconds. This is at least a mountain level feat probably closer to mountain range strength.
Korg has many great striking feats mostly scaling off of other characters
In these scans Korg bust through concrete walls, uses his fingers to climb a dome, and breaks through an arena that is meant to hold alien gladiators. Korg also gets the better of Hulk at the beginning of Planet Hulk and knocks him to the ground.
Easily knocks out Wonder-Man who can take hits from Savage Hulk.
Korg slams Thing into the ground with one punch, dealing heavy amounts of damage. Thing is a high mid tier to low high tier who has contended with weaker versions of the Hulk before,.
Korg punches through Hirom, the second most powerful of the Warbound. Hirom has some good durability feats such as surviving energy blast that have dissolved Humans.
Durability is Korg's greatest attribute as he is comparable to Luke Cage, in the sense of having unbreakable skin, but on a much greater level.
Korg has multiple feats of no selling bullets from Tanks, machine guns and even advanced alien lasers. He also no sells tank shells and giant bugs can't break his skin with their claws.
Korg has great temperature resistance as seen by him no selling the bitter cold, being born out of lava, not being fazed by standing right next to Sentry's great energy blast. and no selling being in lava from the planet of Sakaar twice.
Korg has solid explosive durability as he is not fazed by a blast that disintegrates pinkies who have better physicals than humans. The damage from that blast can be seen in the first scan. Korg also no sells an oil tanker being thrown onto him and tanks a massive explosion as well.
Korg has great blunt forced durability as well tanking hits from Elloe another member of Hulk's Warbound while she was amped by gamma energy. Tanks getting crushed by Hulk, no sells Hulk's headbutt, tanks getting thrown by Hulk, no sells falling from the sky and making a massive crater, jumping off cliffs, and tanks falling from space.
Margus, Korgs brother's skin couldn't be broken by the Hulk's best swings so the Hulk uses Korg as a battering ram as the only way to break Margus's skin. When Korg fought Thor, Thor with Mjolnir couldn't do more than just chip a few pieces of rock off Korg
Korg takes a powerful hit by hulk with two hands that was meant to kill Miek, the next two scans show what a hulk with the same level of strength did while putting in less effort.
Kurg no sells a head shot from Wonder-Man and takes a powerful hit from Silver Surfer that sends him flying into a wall(Silver Surfer was stomping the Warbound + Hulk for most of the fight so accurate Surfer).
This is a much shorter section. Korg isn't stupid per say, but most Hulk comics without Banner don't focus on intelligence feats.
Korg and other Kronans build a mighty robot with an AI, Korg can also build weapons as a blacksmith, and Korg has fight smarts as he realizes that he needs to make Hulk mad so he can shift the Tectonic plates on Sakaar.
Korg doesn't have the best showings of skill, but he does have a couple.
Korg uses a headlock on Abomination, and uses a sword in the arena.
Korg has a few special abilities as well.
Korg can speak to the stone of Sakaar to know what is happening to the planet. Oxygen also boost the stats of Kronans.
Korg may look like a big lumbering pile of rocks, but he does have some decent speed feats.
Korg has some good travel speed feats such as jumping long distances, can keep up with Zazu the saber tooth tiger while running, and leaves humans in the dust.
In the scans above Korg dives under Hulk's arms before he can bring them down on Miek, is fast enough to catch Hulk off-guard in their training match. Is fast enough to get in the way to block bullets for his fellow Warbound and is fast enough to swat down a tank missile.
If there were any feats please share them so I can update this thread.
