Opa-Opa

Opa-Opa is the main protagonist of most games in the Fantasy Zone series. It was debuted in 1986 alongside the first game, which was been proved popular among Sega fans at the Arcades.

In most games, Opa-Opa is the defender of Fantasy Zone planetary ecosystem, alongside Harrier and Uriah from Space Harrier. Opa-Opa defeated countless enemies in multiple wars against the Menon forces, including his dark version, Dark Opa-Opa.

Fantasy Zone series
In Fantasy Zone, Opa-Opa is a warrior which fights against Menon forces due to constant robbery of money in favor of constructing their own fortress. In the end, it was revealed that Opa-Opa's father, O-Papa, was behind them.

In Fantasy Zone II: The Tears of Opa-Opa, set ten years after the events of the original, Opa-Opa fights against the Menon forces once again, this time, by travelling constantly through portals.

From Fantasy Zone: The Maze (known as Opa Opa in Japan), the third game in the Fantasy Zone series, Opa-Opa and his brother, Upa-Upa, is set in a combat training against Menon forces to equip weapons for future war purposes in Fantasy Zone.

In Galactic Protector, Opa-Opa and Upa-Upa try to defend several planets against colliding meteorites and other space debris that can damage themselves. The game is markable for being the first and only game in the Fantasy Zone series where Opa-Opa actually spoke the human language, either by his Opa! death scream or the Perfect! speech.

Since Sega largely abandoned Fantasy Zone in the 90s, Sanritsu, who later become SIMS, made and released Fantasy Zone Gear (known just as Fantasy Zone in Western markets, published by Sega themselves). In this game, Opa-Opa is no more the protagonist, but rather, a captive from dark forces. His son, Opa-Opa Jr., is now the protagonist and fights to rescue his father and friends.

On 1992, Sunsoft made and released Super Fantasy Zone for Sega Genesis. In it, Opa-Opa is the protagonist again and makes revenge for the death of his dad, O-Papa.

M2's intake in Fantasy Zone II, Fantasy Zone II: The Tears of Opa-Opa DX, revamps the original story and adds a new dark nemesis, Dark Opa-Opa, which can be the player itself as the game progress, depending of the conditions.

In the unreleased title Space Fantasy Zone for NEC's Super CD-ROM² system, Opa-Opa is taken in an alternative way of dealing with enemies from Menon forces, this time a la Space Harrier and Galaxy Force II. The history is largely the same, albeit with several new elements, such as the Shopkeeper from Weaponalds.

Opa-Opa appears in NTV's Akai Koudan Zillion anime (known as Red Photon Zillion in the US and just as Zillion in other regions and the games) as one of the cast's main characters. His brother, Upa-Upa, and his father, O-Papa, are also mentioned.
