In Hinduism, martial arts were invented by none other than Vishnu himself. At least, surprisingly enough, the incarnation of Vishnu concerned with peace. In Hinduism, it is not quite polytheism, so much as Vishnu having many different incarnations, one of them being the "god of peace." The incarnation of Vishnu concerned with peace surprisingly enough, NOT Kali, is the one credited with inventing martial arts.
Krishna is an avatar of Lord Vishnu in Hinduism. He is revered as the eighth incarnation of Lord Vishnu and is considered a supreme deity by many devotees. Krishna is known for his playful and mischievous nature as a child, his teachings in the Bhagavad Gita, and his role in various mythological stories and scriptures.
Since Rama is incarnation of Sri Vishnu, hence Rama is god and worshipped as god.
