Dark Opa-Opa is the main antagonist and final boss from Fantasy Zone II: The Tears of Opa-Opa.
The Dark Opa-Opa is an evil alter-ego of the hero Opa-Opa which resided inside him, born from the emotional stress he devolved after having to fight his own father Opapa, though Opa-Opa was unaware of its existence. This dark personality sought to take over his good persona and eventually destroy the Fantasy Zone. Opapa sensed the existence of this dark persona and its evil intentions, so he created a reverse warp gate and made Opa-Opa dive into his own inner world in order to defeat his evil personality. Opa-Opa eventually fights his evil self and destroys him, once again bringing peace to the Fantasy Zone.
