Fucha is the main villain in the Giana Sisters series. Much like all other enemies in the games, Fucha is one of Giana's stuffed toys, in this case a green dragon, which is granted life inside Giana's dreams thanks to her crystals. Fucha serves as the boss of all worlds in the earlier games, spitting fireballs and flying around.

In Giana Sisters: Twisted Dreams, Fucha once again serves as the main antagonist, eating Giana's sister Maria right at the beginning of the game and running away when Maria starts attacking him from his inside. He is given a overhaul, appearing as a giant red dragon with a more menacing look.
