Ard-Con was a Kree Eternal, a sub-race created a long time ago as part of the Celestials' experiments.[1]

He possibly encountered Odin, claiming that that name recalled him distant memories, but that Odin lived no more.[2]

Along with other Kree Eternals, Ard-Con journeyed through space and traveled to Earth, 4000 years ago. Mistaken for Gods by the Celts, all Kree Eternals soon left, save for Ard-Con who lived there for a millennium, was imprisoned by Tantalus.[1]

as Demon Druid


Ard-Con awakened due to the vibration caused by Thor who stroke the ground with Mjolnir to turn himself back into Donald Blake, arriving in Charring Cross, London.[2]

Freeing himself from his rock prison, the Demon Druid wrecked the street, and blasted Thor unconscious, refusing to speak to him. He then resumed to his mission, intending to find rest once more.[2]

In his course, he was assaulted by the British Army, then once again by Thor in the district of Esher on the Portmouth road, and a last time at Salisbury Plain in Wiltshire county, next to Stonehenge.[2]

As Thor was able to stun for a minute, Scotland Yard Inspector Prichard intervened, noting that the Demon Druid was merely trying to reach a portal located at Stonehenge to escape Earth. Free of further attacks, Ard-Con used Stonehenge, his transportation pad, to depart Earth.[2]

Return to Earth

Unable to reach his people,[1] Ard-Con later returned at Arthur's Seat, Edinburgh, via a portal created from two tourists there, and reiterated his trick on the mutant Meggan. The intervention of Shadowcat and of her phasing powers forced him to retreat, freeing both tourists and Meggan and allowing Rachel to gather some of Ard-Con's knowledge about his people's place.[4][1]

He soon broke into Darkmoor Nuclear Research Facility, recreating a nuclear facsimile of Stonehenge, having for plan to power a portal to return to his own people. As Excalibur intervened, Shadowcat understood Ard-Con's intent, and sent Phoenix stop Captain Britain from engaging the fight, buying some time for her to use Widget to open him a portal to his kind, connect with him via Rachel's telepathy and apologized for their behaviors.[4]

Return to the Kree

The portal successfully led him home, but his people were all gone. He renamed himself Ultimus and[1] He was soon found by the Supreme Intelligence,[5] who revealed him his status as last Kree Eternal,[1] and assigned by Supremor to the Kree Starforce along with Shatterax, Korath the Pursuer,[6] Captain Atlas and Dr. Minerva.[7]

They were sent to take down the Avengers infiltrated on Kree-Lar, Ultimus taking on Hercules and besting him. After a brawl, they had the Avengers surrounded.[7]

Conjoint Kree rulers Ael-Dan and Dar-Benn intervened, thanked the Starforce for their capture, then intended to execute both teams, locking them into a force field. At that time, the two Kree emperors were killed by Deathbird, allowing the Supreme Intelligence to regain control of the Kree Empire. He then decided to sent the Starforce to Chandilar, led by Ronan, to retaliate the assassination.[7]

Teleporting themselves into the Shi'ar palace, Ultimus attacked Lilandra, dispatched Earthquake, but was distracted by Starfox long enough for Lilandra to shoot the Kree in the back.[8]

All of the Starforce was captured, and sentenced them to death, leading to the opposition of the Avengers. The battle stopped when counselor Araki was revealed to have been replaced by a Skrull. Lilandra released Ultimus for him to report the Skrulls' machinations, informing him of the disappearance of a Nega-Bomb originally sent on the Kree.[3]

The Starforce escorted Lilandra along with the Imperial Guard, as she came to claim Hala and Kree territory as Shi'ar, making of Deathbird Shi'ar viceroy and Kree ruler, and of the Starforce her Imperial Guard.[9] Under Deathbird's lead, they attacked Quasar and his allies for their violation of the now Shi'ar space, forcing them to retreat.[10]

When the Kree Empire later regained its autonomy, Starforce members were branded as defectors.[11] His current fate is unknown.


Ultimus is a Kree Eternal. As a result, he possesses superhuman powers similar to those possessed by the Eternals of Earth and Titan, offshoots of humans.

  • Superhuman Strength: Ard-Con possesses great superhuman strength surpassing that of the Kree, beng able to lift 75 tons.[1] He was stated to be class 90 tons.[12] He was able to stun Thor for two hours with a single punch.[2]
  • Superhuman Speed[12]
  • Superhuman Stamina[12]
  • Metahuman Durability:[12] Ard-Con can withstand powerful impact forces such as being struck by Thor[2] or Hercules[7], exposure to extremes of temperature[4] and pressure, and powerful energy blasts without being injured.[4] The limits of his durability was seemingly a full Mjolnir blast, and even then he was able to blast back before falling.[2]
  • Superhuman Agility[12]
  • Superhuman Reflexes[12]
  • Energy Manipulation
    • Cosmic Energy Manipulation: Ard-Con can manipulate great amounts of cosmic energy for a number of purposes, though only a few have been seen. Ultimus typically uses these powers primarily for combat situations.

      • Force Field: He can generate a powerful force field around himself[2] and control the radius of the field from a radius of one-inch to several yards.[1]
      • Superhuman Longevity: Due to his unique nature, Ard-Con' aging process is altered. He is immune to all known Earthly diseases and infections and is able to survive indefinitely without food or water, as he was buried under Stonehenge for more than 3,000 years.

Telepathic Immunity: Ard-Con stated that Starfox's mind tricks were ineffective against a Kree Eternal.[8]


Ultimus is a good hand to hand combatant.[12] He is very adapt at using his energy powers coupled with his great strength during combat situations.[8]
