Guff

Guff was a Covenant Grunt who served onboard the Rapid Conversion. At the time of the First Battle of Harvest he fought by Flim and Dadab's side on the Tiara station. During a fight, Guff was able to wound Colonial Militia recruit Dass, but before he could finish him off, he was killed by Staff Sergeant Johnson.

Trivia

 * It's possible that the name Guff may be an attempt at humour. Guff is used colloquially in Britain to describe, amongst other things, breaking wind. This could be a play on the fact that Unggoy breathe methane.
