Hell, even W, OOO, and Fourze can be invalidated because Foundation X is still on the loose.

For what it's worth, Kiva's ending was pretty bad, and I hated that it meant Kiva II has to continue fighting.

The other endings, though, are different. They're not implying that all their work will be for naught, that their descendants will have to fight, and their descendants, and so on.
There's a difference between killing the boss and having a few underlings still around, and killing the boss and telling the viewers that their work amounted to nothing.
(Also, the remaining 2 Undead in Blade are saving the world by existing. You know that)
