Kryptonian Physiology: Kal-Il's race evolved to the point were they could gain great power from the radiation of their planet. The radioactive remains of Krypton give an even greater power to Ultraman who can absorb and process that radiation inside his own body to gain an immense array of abilities. The more Green Kryptonite he absorbs the longer he can use his abilities.
Kryptonite Radiation Absorption: Ultraman's cellular structure allows him to absorb, store and metabolize Green Kryptonite to fuel all of his abilities. He can do this by either eating it or inhaling it after turning the mineral to dust.
Enhanced Abilities: Ultraman has upper level super human strength, endurance and durability.
Invulnerability: Ultraman's body is extremely impervious to harm, and it is nearly impossible to harm.
Flight: Ultraman can defy gravity and fly at incredible speeds.
Ultraspeed: Ultraman is fast enough to fly from the Earth's surface to the moon's orbit in a matter of seconds.

Born on Krypton, through the machinations of his father Jor-Il, a mysterious being came to the planet and began a process that would lead to its destruction. Thanks to a shooting spree, Jor-Il was able to secure a lifepod for his son, whom he regarded as his best chance of revenge.
Rocketing to Earth, Kal-Il was inundated with ideology and moralizing, warning him to be the strongest possible being, eschewing all weakness in himself and in others. His rocket crash landed in Smallville, Kansas, right through the roof of the home of Johnny and Martha Kent. Kal-Il gained power from the Kryptonite and forced the couple to be his parents and stayed with them until he was seven years old, at which point he killed them and burned their farm to the ground. Over the following years, Kal-Il took the name Ultraman and began his pursuits of taking over Earth by murdering the President of the United States and forming the Crime Syndicate. During this time Ultraman had a dysfunctional relationship with his team-mate Superwoman. Unknown to him, Superwoman had a secret affair with Owlman.
Unfortunately for Ultraman and the Crime Syndicate, their stranglehold over the planet was pried loose by the arrival of the being who destroyed Earth just as it had destroyed Krypton. At that same moment, the fabric between universes was weakened by the actions of another powerful being on another universe, thus he, along with the rest of the members of the Crime Syndicate, sought to escape to that other universe and were trapped in an inter-dimensional Limbo for five years, with only Alfred and Atomica successfully crossing. Going by The Outsider, Alfred created the Secret Society of Super-Villains which manipulated the heroes of that universe into reaching him the Pandora's Box in order to open it, allowing the Crime Syndicate to finally enter the Prime universe.
