Doomsday

Powers & Abilities

Immortality– As a result of his unique genetics, Doomsday has the ability to involuntarily return from death unassisted. Because of this, Doomsday could be considered immortal. The amount of time it takes for him to return to life usually depends on the way in which he died. For example, if his death was similar to the one he suffered at the hands of Imperiex when the Hollower of Galaxies reduced him to a skeleton, the resurrection process could very well take thousands of years. Thanks to the makeup of his DNA, Doomsday is able to adapt and become impervious to the cause of his death the next time he is born.
Reactive Adaptation– All the suffering that Doomsday experienced helped him to become stronger but drove him to hate all life. As a result of surviving prehistoric Krypton and its savage inhabitants, Doomsday seems to have an innate ability to sense Kryptonians. Doomsday's very being has grown to loathe Kryptonians even more than any other form of life. If he is not injured beyond his ability to recover, Doomsday's reactive adaptation will make him more invulnerable as he fights. Good examples of this are when he breathed flames against the Martian Manhunter;elongated his knuckle protrusions to attack Superman in the air; or canceled out Radiant, a being of pure energy, by generating an aura of energy and slamming it into Radiant. Also in Superman/Batman #47, Doomsday was recreated with Kryptonite crystals instead of his usual bone extensions.
Accelerated Healing– Doomsday has an exceptionally fast healing factor that enables him to regenerate from damage almost instantly. It could be speculated that his healing factor is what allows him to return from the dead and evolve resistances.
Controlled Bone Growth – Doomsday possesses large, thorny, bone protrusions covering his chest, back, knees, elbows, shoulders, knuckles, chin, eyebrows, and eyes. The durable spikes are razor sharp, and have caused injury to opponents generally considered invulnerable such as Superman and Darkseid. It is possible that these protrusions are a resistance that Doomsday has evolved.
Super Strength – Doomsday possesses vast physical strength. Engaging Doomsday in physical combat will mean almost certain death; almost 100% of those who have challenged him have lost their lives. He even once knocked out Darkseid, the lord of Apokolips. He has also been able to match the strength of Superman in their fights, and in the "Hunter/Prey" mini series, he was able to break Superman's arm, despite the fact that Superman had experienced an increase in power. During "Our World's at War," Doomsday was able to tear apart Imperiex Drones, seemingly doing so with relative ease. This ultimately means that Doomsday can make lifts greatly in excess of 100 tons effortlessly, making him one of the most physically powerful beings in the universe. Doomsday's strength allows him to leap miles at a time, as well; he often uses this as a means of travel.
Invulnerability – Unless tested with blows of astronomical physical force that rival or exceed his own, the Ultimate Lifeform is effectively invulnerable. His nigh-impervious hide has withstood punches from Superman, Maxima, and various blunt force attacks from other powerhouses such as Wonder Woman and the Martian Manhunter. He has proven that he can survive in the most vicious environments indefinitely, including space. His body is mostly solid, with his few vital organs protected by thick layers of bone.
Enhanced Stamina – Doomsday has demonstrated seemingly inexhaustible amounts of stamina. He demonstrated the ability to fight Superman for an entire day without tiring. He also does not need to eat, drink, sleep, or even breathe. However, his stamina is far from unlimited, as was shown at the end of Death of Superman arc.
Super Speed – During his climactic battle with various Justice League members in "the Death of Superman" story arc, Maxima commented on Doomsday's speed when he ducked out of the way of one of her punches. He has been shown able to incapacitate most of the Justice League in only a matter of seconds and attack opponents who have incredible superhuman speed and reflexes.
Intellect (Formerly) – In his latest rebirth, Doomsday finally gains intelligence. Though this is later undone, it is possible he may again develop this ability.

Evolved Abilities/Adaptation

Over his many lifetimes, Doomsday has acquired many abilities:


Telepathic Immunity- Doomsday seemed to have been stopped in his tracks by Martian Manhunter's telepathy, but overcame it after taking a few punches.
Kryptonite Immunity- Doomsday had a weakness to Kryptonite due to his Kryptonian origin, but he overcame that weakness after exposure.
Fire Breathing- Doomsday developed fire breath in order to defeat Martian Manhunter, and later used the same ability against Superman.
Intangibility Bypass- While being controlled by Brainiac, Doomsday was able to bypass Martian intangibility
Energy Aura- When faced by the energy being Radiant, who first killed him, Doomsday evolved an energy aura that was capable of canceling out the Radiant's energy and destroy him.
Energy Feedback- Waverider attempted to shut down whatever Doomsday uses as a nervous system. Unfortunately for him, Doomsday was able to cause an energy feedback, overwhelming Waverider with his own energies and knocking him out.
Bone Projectiles- In Hunter/Prey, Superman uses his flight advantage against Doomsday, only to find that Doomsday evolved a bone projectile that penetrated Superman's shoulder. These projectile were still connected, like a harpoon, and Doomsday used them to reel Superman back in
