This is an all out brawl. Who of these powerhouses do you think would be the last one standing?
These are the classic versions of them.
Let's look at some of their abilities:
Kalibak possess enormous strength, roughly equel to that of Superman. Darkseid also enhanced Kalibaks strength to outmatch Orion in hand-to-hand combat. He is also incredibly resistant to blunt trauma, possesess superhuman stamina and despite his size he's very fast and agile. He also carries a beta club, effective at close-combat and ranged combat.
Abomination is strong enough to lift somewhere in excess of 200 tons and is twice as strong as Hulk in Hulks "calm" state. He also has enough mass and strength to punch with a maximum force equivalent to 500 pounds of TNT. He also possesses enough durability to withstand great heat without blistering, up to 3,500 Fahrenheit, great cold without freezing, down to -175 Fahrenheit, and great impacts without injury. Thanks to his great strength he also possesess superhuman speed and stamina. He also has a healing factor.
Solomon Grundy is strong enough to lift far above 100 tons, and to take on Superman toe-to-toe. He also possesses superhuman durability (resilient to bullets, heat, cold and blunt trauma) and superhuman stamina.
Banes venom makes him able to lift up to 2 tons (he can actially lift 3 tons but not without losing control over himself), and to withstand powerful blows from metahumans, multiple bullets and explosions.He also possesses superhuman stamina and enhanced speed and reflexes.
Doomsday possesess enough strength to bend and break through reinforced steel, destroy impenetrable barriers, and lift extremely heavy objects. He is also resilient to almost all kinds of physical and mental harm. Explosives wont leave a mark on him and bullets bounces off of him. He also possesess superhuman stamina, speed and reflexes.
Now, since they are brawlers who like to slug it out, they are most likely to punch each other until the others fall.
