Hinduism

Lord Kalki, the Lord of the universe, will mount His swift horse Devadatta and, sword in hand, travel over the earth exhibiting His eight mystic opulences and eight special qualities of Godhead. Displaying His unequaled effulgence and riding with great speed, He will kill by the millions those thieves who have dared dress as kings. After all the imposter kings have been killed, the residents of the cities andtowns will feel the breezes carrying the most sacred fragrance of the sandalwood paste and oher decorations of Lord Vasudeva, and their minds will thereby become transcendentally pure. When Lord Vasudeva, the Supreme Personality of Godhead, appears in their hearts in His transcendental form of goodneess, the remaining citizens will abundantly repopulate the earth. When the Supreme Lord has appeared on earth as Kalki, the maintainer of religion, Saya-yuga will begin, and human society will bring forth progeny in the mode of goodness.

Christianity

I saw heaven standing open and there before me was a white horse, whose rider is called Faithful and True. With justice he judges and makes war. His eyes are like blazing fire, and on his head are many crowns [diadems]. He has a name written on him that no one but he himself knows. He is dressed in a robe dipped in blood, and his name is the Word of God. The armies of heaven were following him, riding on white horses and dressed in fine linen, white and clean. Out of his mouth comes a sharp sword with which to strike down the nations. "He will rule them with an iron scepter." He treads the winepress of the fury of the wrath of God Almighty. On his robe and on his thigh he has this name written:KING OF KINGS AND LORD OF LORDS. {Rev 19:11-16 NIV}
