Bellerophon: Bridle of Chivalry (騎英の手綱, Kiei no Tadzuna?) is a shining golden bridle and whip paired as a set that is capable of fully controlling a Divine Beast. It is an oddity even among Noble Phantasms, having no effect without a mount. Its power is great, providing extraordinary offensive and defensive capabilities of the highest level. While Rider alone is not able to match Saber in battle, she is confident in its ability to defeat any opponent without them stopping her charge. Sharing its name with Bellerophon, the man who tamed and rode Pegasus in Greek mythology, she uses it with her Pegasus, allowing it to display its full power even with its normally docile nature.
Pegasus is already an exceptional beast, and directing it with Bellerophon removes its limiters, causing it to rage under Rider's command. All of its abilities are increased by one rank, and its defensive power, already on the level of a dragon, is improved several times due to the protection provided by its massive amount of prana and divine protection. The "Armor Class" rank is raised by one hundred, and the maximum speed that the charge of the beast can reach is between four hundred and five hundred kilometers per hour. Once fastened, it allows for the mounted beast to use its most powerful charge to physically destroy the target, and it must be fastened after the mount is summoned or simultaneously as it emerges from the summoning circle. Compared to the golden flare of Excalibur, the arrow of light can be called a white comet.
As it is a powerful ability, it is not suited for ground combat in normal situations. Although she can fasten and mount it immediately after it leaves the summoning circle, she prefers to utilize it in the air away from onlookers. She has the Pegasus fly high into the air, descending down like divine lightning. It grows large enough to engulf the Center Building's rooftop and destroy the building itself. With assistance from Shirou's Rho Aias, it is capable of defeating Excalibur after ninety percent of Bellerophon's light is offset.

Bridle of Chivalry [Noble Phantasm]
An atypical Noble Phantasm. A weapon set consisted of a rein and a whip. Of course, it had no power by itself.
As a Noble Phantasm, it had A+ rank, with abnormally high attack as well as defensive powers.
A Pegasus under the control of Bellerophon would exceed its limits and receive a rank-up in all of its attributes. Furthermore, due to the protection of an immense amount of mana from Bellerophon, the defensive power of the Pegasus would multiply several times.
If Saber's Excalibur was a golden beam, then Rider was the white comet.
Mmm, as an aside, the name of the young man who rode the Pegasus in Greek legend was Bellerophon.
