There is a character called Agni in the manga/anime series "Kuroshitsuji" (Black Butler) by Yana Toboso. He is the butler of an Indian prince Soma Asman Kadar. He is called "The Right Hand of God" for his curry making skills and is able to stand equal in fight with a demon.

Agni is a feminine Greek name. It comes from the Greek adjective αγνός (agnos) which means pure, clean, chaste, unspoilt.
In English Agni is pronounced similarly to the word "acne". Not that this issue has a bearing on the name when used in other languages. It is simply something to consider given globalization.

I first heard this name used in Avatar: The Last Airbender, as noted above, since it is the name of Agni Kai, which literally means "fire meeting", as according to this site and Avatar Wiki, Agni means "fire" in Sanskrit and kai means "meeting" in Japanese. This is quite a cool name, a great character name in my opinion.
