What If...? (1977) #27

• First appearance and apparent death of Chief Engineer Arlok (see note below).

• "What if... the Phoenix had not Died?" – (Earth-81727) – Uatu ponders over the story of the Jean Grey as the Phoenix and recalls her journey alongside the X-Men. He sees an alternate reality where she did not die during the incursion with the Shi'ar. In this alternate reality, she was reborn again and when the X-Men are called to battle Galactus and Terrax in the Shi'ar galaxy, she unleashes the Phoenix force. She stops Galactus and is thanked by Lilandra for this. She begins to be overwhelmed by the Phoenix force and destroys asteroids and a small star. Upon returning to the X-Mansion, Shadowcat chastises her for destroying another star. Jean again delves into the Dark Phoenix form and destroys Shadowcat. The X-Men try to stop her and she kills Polaris as well. Cyclops tries to stop her and she kills him. This causes her to be engulfed in the Phoneix force and she destroys the Earth.

• "Untold Tales Of The Marvel Universe: Kree Encounter!" – (Earth-616) – Uatu recalls the story of Astron on the planet Uranus. He has found the Kree Sentry #213 destroyed. He goes to speak to his fellow exiled members and tells Uranos to stop the destruction of the Kree weapons. Uranos calls him a coward and says he is building a spaceship to travel back to Earth. Astron tells Uranos he is not leaving Uranus and he is left on the planet. Uranos heads toward Earth as the Kree land on Uranus and realize their Sentry is destroyed. They chase after Uranos' ship and blow it up as it passes Saturn.

NOTE: Arlok was an Eternal and a follower of Uranos, exiled by Kronos. He was among the Eternals banished from Earth. Uranos followers made their way to Uranus and found a Kree outpost and a Kree ship there. Arlok repaired the ship and the majority of Uranos's followers left Uranus but were soon shot down over Saturn's moon Titan. The Kree gained the corpse of Arlok from the ship's debris, and from the knowledge and genetic material they harvested from Arlok's corpse, the Kree were able to create the Inhumans.
