Monk

The Monk is a minor ally from Samurai Jack: The Amulet of Time.

The Monk appears to him at the beginning of the game after Jack has spent a while in his domain to give him the quest for the Amulet of Time. When Jack finally uses the amulet at the end of the game, it returns him to the monk, who speculates that while he no longer has the amulet, he might see it again in the future...

It is unknown how the past Aku's destruction affected his existence.
