Immortal villains

Just out of curiosity, does anybody know any villains whether in literature, tv shows, or movies, that are immortal.  I just have a sudden interest in knowing about them and even better their fates.

immortal villians probably somehow end up being locked in somthing...like a magic lamp or something

Apocalypse is nigh on immortal ... also Spawn, but he is not a villain as such.

Hmm Im thinking Bowser...although time has passed he doesn´t show any sign of aging...or then again he may have an excellent diet

This is hard to reply to, as tends to happen in literature, alot of immortal villains are somehow killed at the end of the stories that include them, comic books aside.
Take the Highlander movies. About immortals, who die. How does that factor in?
Or the terminators, they were machines and hence not living anyway, and were considered indestructible and unstoppable, up until they got all crushy crushy melty melty.

The only truly immortal villian (and really his role as villian is questionable ) i can come up with is the Saint of Killers from the Preacher comics.

Algol from Soul Calibur IV is immortal. 

Heath Ledgers acting in The Dark Knight is immortal.

Chuck Norris is immortal...

I know that Morgoth/Melkor and Sauron were banished out of Arda and Illuvatar locked them up at the pleading of the Valar.

Adam Monroe/Takezo Kensei in Heroes is immortal.
Apocalypse in X-men is immortal.
Elves are immortal, in this case from The Lord of the RIngs.
That guy from Lost Odyssey is immortal.

Elves aren't immortal. They just live so long that they are considered immortal.
