Rick Jones, in particular, played a key role, because the Supreme Intelligence, through elaborate machinations, influenced Captain Marvel to construct a Kree Omni-Wave Projector to stimulate the latent psionic potential, the "Destiny Force", in Jones' mind.
Skrull Empress R'kill and the Kree Supreme Intelligence believed that the war had reached a stalemate and proposed a final resolution through single combat between the Skrull warrior Raksor and the Kree soldier Bel-Dann. The Fantastic Four and the Inhumans goaded the combatants until they joined forces to ward off their attackers.
The arbiter of the battle, Uatu the Watcher, commented that their willingness to cooperate demonstrated that the Kree and Skrull could work together too. In the aftermath of the conflict, the Illuminati paid a visit to the Skrulls, making it clear that they would not tolerate involving Earth further in the conflict much longer.
