Doomsday

Doomsday is one of the main antagonists of ''Superman: Guardian of Mankind. ''He is a rampaging, murderous monster and demon who is the result of Kryptonian genetic engineering gone awry and his motives are merciless and destructive.

Personality
Doomsday is an extremely ferocious monstrous being with an insatiable bloodlust, desire for destruction and carnage, which makes him a nearly unstoppable threat of apocalyptic proportions. However, due to Doomsday's feral mind, he therefore has a limited intelligence, being unable to tell the difference between friend and foe and thus owes allegiance to no one but himself.

Powers and Abilities

 * Mutated Kryptonian Alien Demon and Titan Physiology: Doomsday is a terrifyingly powerful being of potentially apocalyptic proportions. He has the ability to evolve and regenerate at a rapid pace which makes him impossible to be brought down with brute force alone.
 * ​Super Strength: Doomsday has a tremendous level of superhuman strength, virtually incalculable. Thus, Doomsday is strong enough to generate large shockwaves with his monstrous blows, to hold his own against Kryptonians and can actually harm and kill a Kryptonian without Kryptonite.
 * ​Super Leaps: Doomsday is able to use his incredible strength to perform super jumps.
 * Super Speed: Doomsday can move at considerable superhuman speeds.
 * Super Stamina: Doomsday has incredible, virtually inexhaustible stamina.
 * ​Super Reflexes: Doomsday's speed extends to his reflexes as well, being able to easily catch bullets and projectiles and catch punches from other super-speed beings. Later, Superman was able to easily dodge attacks and can move faster than an object can be affected by gravity.
 * Invulnerability: Doomsday is virtually invincible, with the monster being unscathed by the intense firepower of military jets, tremendous blows from Kryptonians and other powerful beings, and can even quickly recover from a megaton nuke's full force and can recover falling all the way down to Earth from space.
 * Flight: Doomsday can fly via manipulation to his own gravitational field, taking advantage of Earth's weaker gravity to propel himself through the skies and even beyond the planet's atmosphere. Upon mastering this technique, Superman can fly at hypersonic speeds that allow him to circle the globe in moments.
 * Healing Factor: Doomsday has an extremely effective healing factor, making him incredibly hard to defeat, even for the most powerful of opponents. Doomsday can recover and heal almost instantly from nuclear explosions, and grow huge bony protrusion if a limb is dismembered. Whatever injured, Doomsday's healing wounds are instantly enveloped in an orange superheated glow, which vanishes after he is healed, mere seconds later.
 * ​Regenerative Evolution: Doomsday can not only heal from injuries, but his body can mutate further, being an adaptive response to trauma. The more damage he receives, the stronger and more durable Doomsday becomes.
 * Energy Absorption: Doomsday's cells, like those of a Kryptonian, are capable of absorbing multiple kinds of energy, for both sustenance and enhancement. Having absorbed a considerable amount of energy, Doomsday is induced to mutate and increase in power, with him notably growing bony protrusions and growing in size after surviving many destructive things. Doomsday can also absorb kinetic energy from a powerful being's blows, with their hits therefore only making him stronger and more powerful.
 * Electrokinesis: Doomsday, when healing from a powerful attack, is capable of generating immense electrical tendrils and shockwaves from his body, with Doomsday generating a larger and more powerful shockwave as he increases in power.
 * Heat Blasts: Doomsday can generate tremendous superheated torrents from his eyes and mouth, which are larger and more destructive than even Kryptonian heat vision, with a single thermal blast being enough to completely destroy a building's entire floor.
 * Super Breath: Doomsday is capable of surviving prolonged periods without oxygen, allowing him to travel at tremendous hypersonic speeds and remain underwater and within the vacuum of space without adverse effects. He can significantly focus the intensity of his breath, capable of freezing objects and targets just by blowing on them.
 * Super Vision: Doomsday possesses superhuman eyesight that encompasses a variety of sensory capabilities including telescopic, infrared, ultraviolet, X-ray and gamma ray visual capabiliites. He can see the entire electromagnetic spectrum when he desires, through mental focus. In his youth, his enhanced vision overwhelmed him, as he saw everything at once, though he managed to hone his senses and bypass that weakness.
 * ​Telescopic Vision: Doomsday has the ability to focus his vision to see something at a great distance by mentally zooming in.
 * X-Ray Vision: Doomsday can focus his vision past layers of matter to see through them.
 * Heat Vision: Doomsday possesses the ability to emit thick beams of intense heat from his eyes. Visually, the power manifests as two thick laser-like beams of red energy firing from his pupils. These beams can be less intense, rendering them invisible, allowing Superman to work undetected. He has extremely fine control of this ability, being able to swiftly cauterize wounds without fatally burning someone. At full power, Superman can utilize his heat vision to instantly disintergrate humans, instantly melt thick steel, swiftly burrow through a glacier, momentarily stun other Kryptonians, destroy objects and even overwhelm stronger beings' defenses.
 * Frost-Breath: Doomsday can produce and spray super-heated ice-like fluid from his mouth through exhalation.
 * Super Hearing: Doomsday is able to hear at extreme variances of sound and pitch frequency, allowing him to pick up numerous sounds from immense distances. Honing his senses, he has enough control to block out ambient sounds to focus on a specific sound or frequency.
 * Super Smell: Doomsday has incredibly acute olfactory senses.

Weaknesses

 * Kryptonite: Doomsday has Kryptonite as his main weakness, with this radioactive green xenomineral being extremely toxic to him, making it the only known substance capable of actually killing the monster.
 * Beings of Equal Power: Doomsday can be effectively engaged in combat by beings of comparable incalculable strength however his healing factor and adaptive evolution makes the monster incredibly hard to kill, even for them.
 * Magic: Doomsday shares Kryptonian's vulnerability to magic.
