Emperor Vandole

Emperor Vandole is the ruler of the Vandole Empire and a major antagonist in the World of Mana video game series, serving as the ultimate antagonist of Sword of Mana and its remake Adventures of Mana and the secondary antagonist of Secret of Mana.

Adventures of Mana
In the backstory of the game, Vandole is stated to be the father of Julius and to have been killed when the Vandole Empire fell.

Sword of Mana
In the past, Vandole used the power of the Mana Tree to create an unstoppable empire, but was defeated by three Gemma Knights using the Sword of Mana.

After Dark Lord's death, however, it is revealed that Julius is a descendant of Vandole and possibly a reincarnation of Vandole himself.

Julius attempts to use power of the Mana Tree to conquer the world and re-establish the Vandole Empire as "Neo-Vandole" but is defeated and killed by the hero's party.

Secret of Mana
Emperor Vandole returns and through the power of Mana, managed to conquer many lands under his Vandole Empire.

Vandole and his four generals seek to unseal the 8 Mana Seeds to obtain the Mana Fortress. However, once the Vandole Empire succeeds in breaking the seals on the 8 Mana Seeds, Vandole is killed off and usurped by Thanatos, having used him to obtain the Mana Fortress all along.

Trivia

 * A diary cut from Secret of Mana reveals that the Vandole in that game was actually a monster in disguise and that the real Vandole was in hiding all along.
