If you go into the south, for some Hindus, Kartikeya, or also known as Murugan, might be a significant deity. That is the god of war. Vishnu is known to have multiple incarnations that are very prominent. The most prominent of which are Rama, Vishnu's seventh incarnation. He is the main protagonist in the Ramayana, the famous Hindu epic. You have Krishna, who is Vishnu's eighth incarnation. And he is a significant figure throughout Hinduism, including the Mahabharata and the subset of the Mahabharata, which is the Bhagavad Gita.
