In the 1994 Sega 32X fighting game Cosmic Carnage, Naja is a playable four-armed, serpent-like alien warrior. In Koei's 2002 action game Mystic Heroes, Naja is featured as one of the four main playable characters, depicted as a young, agile mage who harnesses the power of wind.
Within the narrative of
Cosmic Carnage, the character belongs to the fugitive faction escaping a prison transport ship after a catastrophic space collision. Players can customize this fighter's combat style by choosing between light armor for increased agility or heavy armor for enhanced defensive capabilities. This armor system directly alters the character's moveset and sprite appearance during matches, serving as a key mechanical feature of the title.
In
Mystic Heroes, the character's design and role are heavily inspired by the Chinese mythological figure Nezha, drawing from the classic novel
Fengshen Yanyi. Developed by Koei's Omega Force studio, this iteration fights alongside allies Tai and Liko to thwart the tyrannical Emperor Kang. The character utilizes a specialized spear in melee combat and can chain physical strikes with elemental magic. Across the Nintendo GameCube, PlayStation 2, and Game Boy Advance releases, players level up the character's abilities by collecting and equipping various magical runes found throughout the battlefields.
