Ultimus The only Kree Eternal still known to be alive. 3000 years ago, Ultimus was buried below Stonehenge by the Deviant Lord Tantalus, and remained there until modern times. He was called the "Demon Druid" for a time after being awakened, until the Supreme Intelligence told him of his origins, assigned him the name "Ultimus", and made him a member of Starforce, the team of Kree super-heroes. With Starforce, he aided the Underground Legion in an assault upon Tantalus at Armechadon, using his powers to track Tantalus there. -Thor#209, Excalibur#20, Wonder Man#7, Captain America#399, Avengers#346-347, Thor#446, Avengers West Coast#82, Quasar#35, Blackwulf#7-8

Uni-Mind The collective energy of the Eternals, born of the Ritual of the Uni-Mind. Eternals, Humans, Deviants and Brethren have been a part of Uni-Minds. It is not known how long a Uni-Mind can be held together, but there is one which left earth following Zuras' death, and apparently still exists. It comprises most of the Eternals' population, though Ajak, and possibly others, have left its joining. Zuras was the first Eternal to form a Uni-Mind, after they attained cosmic powers, and used it to determine if he or A'Lars should become Prime Eternal. Since then, the Prime Eternal alone has the power to summon the Ritual, and produce the Blue Flame through which the Eternals fly, their forms physically becoming the Uni-Mind. Varua of the Young Gods is also able to create a joining with her fellow Young Gods which is similiar to the Uni-Mind. -Eternals (v.1)#12, 14, Thor#291, 300, What If (v.1)#25, Avengers#247-248, Eternals (v.2)#12, Spectacular Spider-Man Annual#8, Fantastic Four Annual#23, Avengers#339, 370-371, Marvel Comics Presents#109
