I fully expect Lysandre to show up again too, since he shot himself with the Ultimate Weapon, which logically either killed him (Y) or made him immortal (X), but buried under four tons of rubble and unable to ever escape. Since ZA isn't version specific, I imagine both situations are true, and Lysandre's life is now in perpetual flux.
