Kyubimon is Renamon's Champion level form. Kyubimon is a yellow
nine-tailed fox with a white mane and mystical blue flames flaring
around her paws and tail tips. Kyubimon comes from the word Kyuubi
meaning nine-tailed fox. Kyubimon was inspired by a mythical Japanese
beast, the kitsune.
Rika had wanted Renamon to digivolve for a long time, but wasn't
able to achieve it. However, when the two were attacked by a
Dokugumon, Renamon protected Rika, thus taking the full blast of
Dokugumon's attack. Rika, who had never accepted Renamon as a living
creature before, cries out in sorrow over Renamon's sacrifice. This
emotional response caused Renamon to digivolve to Kyubimon, who was
now able to defeat the Spider Digimon. Renamon later digivolves again
several times to battle the Devas and other evil Digimon in the
Fox Tail Inferno (鬼火玉 Will-o'-the-wisp
Ball): The blue flames on Kyubimon's tails become brighter, and
ghostly faces similar to that of DemiMeramon's appear on them. The
faces then become small fireballs which Kyubimon launches at her
opponents to destroy them in an explosion of energy as well as trap
them in a cage of blue flames which singes them.
Dragon Wheel (狐炎龍 Fox Flame Dragon):
Kyubimon starts to spin very fast, which causes the flames on her body
to erupt into a fiery inferno. This turns her body into a ball of
swirling blue fire. When in this state, Kyubimon summons a mystical
dragon, which emerges from her body to destroy her enemies.
