Sentry
I know Sentry's real good friends with Reed, but here's the scenario: Franklin Richards has been kidnapped by Galactus, and forces FF to try and kill Sentry. Galactus sees Sentry as a great threat to his devouring of earth and other planets, and also seeing the power of Sentry first hand. Who takes this one? And FF can't use the ultimate nullifier. They lost it. Now who wins? Sentry wins this in my book.
