Bracktanus
From Halopedia, the Halo wiki
Bracktanus is a Brute warrior mentioned by a pair of Grunts during the Reach campaign. While he was in an early draft of Halo 2, now he is only mentioned in Conversations from the Universe. He was noted for fighting and killing an Elite in cold blood "within spitting distance" of a holy place. The Prophets forgot the matter, showing favortism for Brutes.
