Hakunin

Hakunin is the village shaman for Arroyo. He will heal you whenever you are hurt, and he gives you the Destroy the Evil Plants quest. After you complete the quest, he will make Healing Powder for you if you give him a Broc Flower and a Xander Root.

He'll also appear to you in several visions you have when dreaming, telling you about the dying village and the Enclave attack, which suggests that Hakunin had some kind of psychic abilities.

Humorously, due to his eccentric choice in words, you can choose to respond with comments on the way he talks, but he doesn't seem to notice. Either everyone criticizes him for this or he just doesn't notice or care.

Appearances in games
Hakunin appears only in Fallout 2. He is a talking head voiced by Dwight Schultz.

Trivia
Even if you kill Hakunin and disrupt the villiage before getting to Vault 13, you will still seem him in a resulting end-game dream.
