In defense of my writeup, I state that finding information about each other is not necessary. If Proctor could, that would be great. But even without any info, the fight still progresses the same way.
Now, both appear on the planet. Proctor sees a guy literally glowing with energy, a riot of fleeing aliens, and Galactus himself destroying the planet. That fact alone tells Proctor he doesn't have time to mess around if he wants to survive. So the battle proceeds instantly.
I said Proctor would try to use his telepathy on New Son, not that it would necessarily work. He may even try his tk to knock New Son around to try and keep him off balance. And even try telepathically ordering the aliens to attack and distract New Son.
At this point, Proctor wants to finish the fight instantly becuase of Galactus, and because he might just see aliens attacking New Son just spontaneously explode. A good hint that Proctor better make this quick. So he goes with a teleport, stab, and overload. Not knowing that New Son's death would wipe out the planet. So he teleports to "safety". New Son explodes, and the energy spreads out to encompass the planet. But there is a time, no matter how short, between New Son's death and Proctor's. During this time, Proctor has won the fight and is transported to safety for use in the next round.
Proctor wins
