|This article is about a/an transformation device in Kamen Rider Wizard.|
The Beast Driver (ビーストドライバー Bīsuto Doraibā) is the transformation device of Kamen Rider Beast, the Secondary Rider of Kamen Rider Wizard. It is activated when the Beast Ring is inserted in the left slot and turned it counter-clockwise, opening the front buckle that reveals the lion head inside. Using a ring in the right slot calls out the name of the Ring, followed by "Go" (ゴー Gō), and a transformation chant for either a Mantle Ring or the Hyper Ring.
When Beast turns the Beast Ring clockwise, he can perform the Strike Beast (ストライクビースト Sutoraiku Bīsuto) finishing attack. His finisher has 4 different variations depending on which Mantle he is currently equipped with. It also has a fifth and sixth variation if Beast uses it either without a Mantle or in Beast Hyper.
- Beast: Beast flies through multiple gold rings, culminating in a roaring lion head appearing on his foot.
- Falco Mantle: N/A
- Chameleo Mantle: N/A
- Buffa Mantle: N/A
- Dolphi Mantle: N/A
- Beast Hyper: Beast Hyper flies through multiple blue and gold rings, culminating in a enhanced roaring lion head appearing on his foot.
When not transformed, the Beast Driver appears as an ordinary belt with a closed gate-shaped buckle. Unlike the WizarDriver, which can utilize any Magic Ring in its inactive state, the Beast Driver must be active to use any ring other than Driver On. Comedically, the Beast Driver can't scan Wizard Rings, since the rings can't be inserted into the Ring Slot.
While wearing the Beast Driver, Nitoh is immune to the temptation of the Fruits of Helheim. Instead, the Beast Chimera will take over the temptation and devours the fruits.
The Beast Driver is found by Kosuke Nitoh during his expedition discovering some ancient ruins and meeting the Beast Chimera, who then forced a pact on the then dumbfounded Kosuke. To his utter surprise, several Ghouls were released within the cavern walls, but he managed to transform for the very first time and defeat them as Kamen Rider Beast.
When the White Wizard begins the second Sabbath, Kosuke realized he's the only person to stop the ritual, as fellow wizards have been imprisoned in order to unwillingly aid the White Wizard while the people of Tokyo are incapacitated by the magical energy being released. Kosuke goes to the ritual location at the center of the magic circle and fights the White Wizard, but is outmatched and defeated easily. When it looks like all is lost, Kosuke has a mental conversation with Chimera in which he realizes that there's still one thing he can do. Stealing the White Wizard's Hamel Cane, he stabs it into the Beast Driver, destroying it and releasing Chimera into the real world, where it disrupts the Sabbath by devouring all the mana being released. Chimera returns and a powerless Kosuke asks if it's going to eat him as promised when he first donned the Driver; however, Chimera simply laughs and says that Kosuke is too entertaining to kill, telling the young man that he's free now and flying off into the world.
Magic Land version
The Magic Land Kosuke Nitoh created the Beast Driver based on an ancient book. Here, he never needs to consume Phantom Mana since Beast Chimera is his personal Phantom instead. While in a deactivated state, the belt can also scan normal Wizard Rings by scanning it on the front buckle.
- The design of the belt is similar to the Shogun Buckle from Power Rangers Super Samurai. It should be known that PLEX designed both belts.
- The DX Beast Driver will announce "No!!" as an error sound if the Beast Ring stays on the insertion of it too long.
