Nag

Nag is a black cobra and a main antagonist from Rudyard Kipling's short story, Rikki-Tikki-Tavi and the animated short based off it.

Nag is the husband of Nagaina and the enemy of Rikki-Tikki-Tavi the mongoose. Nag and Nagainia invaded a British family's garden in India, and were fought by Rikki-Tikki, the family's pet. They hated him and tried to get rid of him several times. Nag infiltrated the family's house one night, so he could kill them all in their sleep. But Rikki-Tikki attacked him and they battled. The man came with his gun and shot Nag, but the cobra was already dead; killed by the mongoose. Nagaina then vowed revenge.
