Devadatta: the God-given Stallion (Anti-Army, B)
Kalki's main Noble Phantasm is the white horse he is often depicted with. This horse, Devadatta is a winged stallion comparable in nature to a Pegasus, but not quite as powerful. While he is primarily a means of transportation, he possesses A rank strength and endurance, making him an effective weapon in his own right. On the ground, his normal speed is comparable to a bullet train; in the air, an F-15.
Parabrahman: Evil Slayer (Anti-Evil, A+)
The sword Kalki wields, named after the ultimate form of divinity, possesses an innate advantage over evil. Anything of adharma that it touches will receive massive damage, with the sword being able to bypass even the strongest of both physical and conceptual defenses. If the sword manages to strike a killing blow, the target will be instantly converted into prana and absorbed by Kalki while their souls are stored, giving him more energy; when Kalki dies, these souls will be released and brought into the presence of the Supreme Being rather than having their Origins recycled (or so Kalki claims; there's no way to prove it). However, it loses all its power against beings who act in line with the Dharma, becoming nothing more than a sword backed by A rank strength.
Satya Yuga: Return to the Phantasmal Age (Anti-World, EX)
If Kalki can be sufficiently motivated to participate in the Grail War, he can create a Bounded Field over a certain area via the placing of Vedic verses. Once at least ten verses have been put down in a perimeter, the Bounded Field will proceed to rip the area of the Present World - the world that huamans live on and perceive - contained within it to shreds. The Reverse Side of the World, the layer of reality where the Phantasmal Races fled to at the end of the Age of Gods, will be revealed within the area of the Bounded Field. At this point, the field will begin to grow naturally, but can also be expanded rapidly through the placement of more verse sigils. Within the Bounded Field, Kalki will gain Authority similar to that of a Divine Spirit; this allows him to terraform parts of the Reverse Side to fit the description of the kingdom he will establish in the Satya Yuga. Within this domain Kalki can set up for himself, those who are either in line with the Dharma (or some other form of divinity) or hail from the Age of Gods themselves will receive a rank up in all parameters. Those from the Age of Man and who defy the Dharma will receive two ranks down.
A weaker, more instantaneous version of this ability can be used, albeit with the price of either extreme prana cost or the use of Parabrahman as a Broken Phantasm. Kalki can channel a white, three-armed energy beam that can achieve the same effect of peeling back the Present World. All enemy Bounded Fields that were active in the area will also be dispelled. Even Reality Marbles can be broken by this ability.
