Kalki
From The SpiritWiki
In Vedic and Buddhist teachings, Kalki is the tenth avatar of Vishnu. Kalki comes at the end of the Kali Yuga in order to "rejuvenate existence" by ushering in the Satya Yuga (age of truth). He is sometimes portrayed as leading an army of warrior priests in order to end persecution and usher in an age of peace and prosperity for all.
