Beast Chimera

Beast Chimera (ビーストキマイラ) is an ancient cannibalistic Phantom who is Kamen Rider Beast's Phantom ally Chimera (キマイラ). Unlike WizarDragon, who was born from within Haruto, Beast Chimera was mysteriously imprisoned in the Beast Driver until it was discovered by Kosuke himself and entered his Underworld while forming a pact with the human, where in exchange for using his Mana, Beast must absorb the mana of defeated Phantoms for Chimera, or Kosuke will pay with his life for failing.

Appearance
Resembling a giant metallic black and gold lion, Beast Chimera is covered in body armor modeled after the four animals that Beast uses in his Mantles:
 * Buffalo (red): Breastplate
 * Falcon (orange): Right shoulder guard and wing.
 * Dolphin (purple): Left shoulder guard and wing.
 * Chameleon (green): Tail

History
A Phantom that was born long ago from a Gate in despair, the Beast Chimera was sealed within the Beast Driver with the item hidden away. But in the present, the Beast Driver was found by Kosuke who broke the seal and caused the manifestation Ghouls. The moment Kosuke used the Beast Driver at his insistence, Beast Chimera entered the human's Underworld and forces a pact on Kosuke, using him to hunt Phantoms to consume their magical energy.

But this pact has a negative effect as Kosuke would die if Beast Chimera can not consume the amassed Phantom mana needed for the human's life to be prolonged. Though Haruto offered to kill the Phantom to free him, since his actions of eliminating Phantoms and preventing the creation of new ones place him in danger, Kosuke turns down the offer on the grounds that Beast Chimera might be too much for Wizard to handle. Later, when Kosuke lost his Beast Driver, Beast Chimera was disappointed because he failed to hold up his end of the pact and now had to devour him despite being "a good lackey". However, Kosuke managed to retrieve the Beast Driver and use the Hyper Ring. Beast Chimera then revisited Kosuke in his Underworld. Much to Beast Chimera's surprise, Kosuke managed to get the Hyper Ring. As a gift, Beast Chimera lends Kosuke his power to activate Beast Hyper form.

When Legion entered Haruto's underworld, Beast and Beast Chimera arrived to aid WizarDragon. Though, even the combined force of two Inner Phantoms could not defeat Legion. When Legion going to kill Beast Chimera, WizarDragon flew in to receive the attack. However, it costs WizarDragon's life.

Separation with Kosuke
"If you wanna eat me, go on ahead." "You never cease to amuse me! Very well, I release you from your obligation. From this day on, you are free, Kosuke Nitoh!"

- Chimera's final regards to Kosuke before leaving

Chimera later gave Kosuke a chance to stop the second Sabbath. But in exchange, Chimera would kill him if he destroyed the Beast Driver. Despite Chimera's warnings, Kosuke destroys the belt and lets Chimera free. Chimera flies and destroys the Sabbath by absorbing all the mana. As he finds how interesting Kosuke was until the end, he laughs satisfied to be with him and tells him that he was free and flies off to parts unknown.

In the aftermath of Haruto's final showdown with Gremlin, Kosuke decided to go and track down Chimera, saying he just had to know more about him. Though he no longer had magic, he was accompanied by Yuzuru Iijima, on weekends when he wasn't at middle school.
