==History==
===1986===
An exceptionally dangerous Fangire that inherited the position of Rook for the Checkmate Four, he became known among the other Demon Races for his vicious actions, having caused the near-extinction of the Wolfen race. 
Around this era, Rook had spent his free time slaughtering others via his own personal game: the "Time Play". In a Time Play, he feeds on a selected type of people within a certain time limit, either rewarding or punishing himself afterwards, depending whether he devoured the right amount of victims within his game. Having murdered Yuri Aso's mother through such means, Rook earned Yuri's wrath, being targeted by her, to his indifference. 
Though Otoya, Yuri, and the Arm Monsters have each attempted to fight Rook on several occasions, the latter proved too powerful in battle, casually swatting them aside as an afterthought. At one point, Rook nearly murdered Otoya in one of their battles, only being stopped per Maya's commands. 
Eventually, making use of Rook's arrogance, Yuri tricks him into using the prototype Ixa System, with Otoya Kurenai and the Arms Monsters as his foes. Severely weakened from the battle, Rook becomes vulnerable to his foes' attacks, recieving a severe wound on his right shoulder by Yuri. Declaring that he will return someday, Rook retreated away, entering a deep rest to recuperate from his injuries.
===2008===
By 2008, though sufficiently recovered, the Rook lost his memories while resting, gaining a kinder and child-like mentality. Founded by Wataru Kurenai/Kamen Rider Kiva and Shizuka Nomura, Rook recieves the nickname as a placeholder for his name, being noticed for his immense size. Placed under the care of a family that cooks soba, Rook became one of their employees, welcomed for his strength and character.
Unfortunately, soon after, "Dai-Chan" regains all of his memories as the Rook upon seeing one of his old battlefields, coldly murdering his former employers and customers. Though Wataru faced him in battle, Rook easily gained the upper hand, having no problems against Kiva Garuru Form. Luckily, Rook decided to retreat mid-way in their fight, much to Wataru's confusion.
Afterwards, Rook would face the Kamen Riders on several other occasions, establishing himself as one of their strongest enemies. However, upon gaining Emperor form, Wataru as Kiva gradually proved himself the stronger combatant, being able to overpower Rook on two occasions. Similarly, Keisuke gained an upgrade as Ixa Rising, allowing him to contend with the Checkmate Four as well.
Eventually, growing bored with his Time Plays, Rook overhears a mother and daughter talk about Heaven, much to his interest. Convinced that he would spend an eternity in joy at Heaven, Rook decided to do good deeds to gain its entrance, randomly helping anyone he sees. 
After witnessing the new Fangire king in person, Rook deemed himself as ready for Heaven. Rook then appears before Megumi, asking that she kill him. When Megumi's weapons prove ineffective, Rook decides to kill her. However, Wataru arrives to save Megumi, causing Rook to fight him. Soon afterwards, Wataru and Keisuke switch foes, the latter becoming Rook's opponent.
Postponing his plans, Rook decides to defeat Keisuke as Ixa Rising, only to be heavily damaged in their battle. Allowing Megumi to land the finishing blow, Keisuke gives her the Ixa system. Transforming into Ixa Burst mode, Megumi slashes the Rook's damaged shoulder with Ixa Judgement, causing him to die.
Later, a zombified Lion Fangire appears among the resurrected Fangire group by Bishop, attacking the Kamen Riders

===World of the Rider War===
The Lion Fangire was among four Fangires who were part of a gathering of monsters which were revived by Super Apollogeist in the World of the Rider War through a surplus of Life Energy which he had gained during his wedding to the Fangire Queen. These four Fangires were combined to create a copy of the strongest Fangire from the World of Kiva, Beetle Fangire. This Beetle Fangire is later destroyed by Kuuga's Mighty Kick. 
==OOO, Den-O, All Riders: Let's Go Kamen Riders==
Due to a change in history caused by Ankh leaving a O Medal behind in 1971, Shocker achieved its goal of world dominion with the Shocker Greeed which defeated the Double Riders, and new members from the various groups that would had manifested in the normal timeline after Shocker's destruction. The Lion Fangire was among the many monsters who were part of the this alliance.

==Video Game appearances==
===Kamen Rider Break Joker===
Lion Fangire appears as a playable character with other Riders and monsters in Kamen Rider Break Joker.
==Personality==
Much like most of his cohorts, Rook was a cruel individual in general, being sadistic and uncaring toward other life-forms. Highly proud of the power and status he held, Rook usually did things on pure whim, hence his brutal actions toward the innocent. This made him an unpredictable foe in general, being subserviant only to the King and Queen themselves. 
During his temporary amnesia, Rook became a completely different being in personality, showing kindness toward others without any ulterior motives. Upon regaining his memories though, Rook quickly reverted back into his old ways, murdering his newfound friends in an instant. 
Driven by his boredom, Rook often conducted his twisted "Time Plays" as a hobby, something others regularly deemed as pure nonsense. Notably, Rook himself eventually lost interest in his games, shifting to an interest in Heaven. Thus, he did good deeds out of superficial reasons before ultimately dying at Megumi's hands.

==Notes==
* The Lion Fangire's hidden bird motif is the dodo. Both sides of the shoulders show the bird's beaks.
* In Kamen Rider Kiva: Final Stage, there is a Lion Fangire that become the Neo Rook. This is a different Fangire that shares the same powers as its spiritual predecessor. 
*Among members of the Checkmate Four, Rook is the only one shown with no particular responsibilities to burden, having no need to protect the near-almighty King or his son in any form. Thus, his disappearance and later death is never seriously touched upon by his allies, essentially being forgotten without a trace. 
*The Rook's "Time Plays" heavily resemble the rituals conducted by the Gurongi, given how both require the participant to slaughter innocent people within a certain time frame.
