Finding himself unable to destroy the immortal Phantom Phoenix, Kamen Rider Wizard was only able to neutralize him permanently by using the power of his newly accessed All Dragon form to Rider Kick the Phantom into the sun, condemning Phoenix to an eternity of perpetual revival within the sun's intense heat.
 * In the apocryphal Kamen Rider Wizard in Magica Land installment Client: Yugo, Koyomi predicts that Phoenix would ultimately become strong enough to escape the sun in a million years' time, but also noted that by that time humanity would be long dead so it wouldn't matter.
