Kree-Skrull War

Later during the Dark Phoenix crisis, the Shi'ar Majestrix Lilandra consulted both the Skrull Empress R'Klll and the Kree Supreme Intelligence regarding Jean Grey, the host of the Phoenix Force, who agreed to a trial of combat between the X-Men and the Shi'ar Imperial Guard to determine Jean's fate. The Kree warrior Bel-Dann and the Skrull warrior Raksor were assigned to observe the duel by their governments and to make sure that the X-Men lost. Soon, the two warriors turned on each other.

For months, the two warriors hunted each other in Attilan's bowels and did battle. Uatu the Watcher observed this and informed the sovereigns of the Kree and Skrull Empires. After much discussion and thought, the two empires decided that they would have the two warriors determine the outcome of the war between the two rival empires. They informed Raksor and Bel-Dann, who were honored to represent their empires in this final battle. The fighting between the two continued for months, undermining the foundations of the Inhumans' city. After Uatu informed the Inhumans and the Fantastic Four of what was happening, they manipulated the two warriors to join forces in combat against the Fantastic Four and the Inhumans. They arranged it so that the heroes were "defeated" by the two, after which Uatu the Watcher interceded, declaring Earth the loser, and the Skrull and Kree Empires both winners, thereby ending the eons-long war.
