Fantasy Zone

Fantasy Zone (ファンタジーゾーン, Fantajī Zōn?) is a surreal arcade game released by Sega in 1986. It was later ported to a wide variety of consoles, including the Sega Master System. The player controls a sentient spaceship named Opa-Opa who fights nonsensical invader enemies in the titular group of planets, full of settings atypical of the traditional scrolling shooter and pastel colors. Opa-Opa is sometimes referred to as Sega's first mascot character.
