Vanitas vs. Ghirahim: Two second-in-command villains originating from the chronologically earliest games in their series, and were created by the earliest villains of their franchises out of pure darkness. They show absolute loyalty to their masters, and are perfectly willing to turn themselves into living weapons, with Ghirahim becoming Demise's sword and Vanitas wielding the X-Blade, to help achieve their master's goals. They will challenge the heroes multiple times throughout their respective stories, growing stronger with each encounter until they eventually unleash their true powers in a climactic duel to the death.

Also, credit to MMYP99 for the idea of Vanitas vs. Ghirahim.

Illumi vs. Kurome: Dark-haired, pale-skinned assassins who also happen to be the siblings of one of the main characters. Despite appearing cold and aloof most of the time, they can be extremely ruthless when provoked. In battle, they have the ability to control the corpses of their enemies using their signature weapons, though Illumi can also control people without killing them. While Illumi fights from a distance by throwing his needles, Kurome fights up-close with her sword.
