'Kree' is the signature battle cry of the Jaffa, the soldiers serving the Goa'uld in Stargate SG-1, the science-fiction series that aired from 1997 to 2007. Shouted as both a war cry and a sharp battlefield command, it became one of the show's most quoted alien phrases. Short clips of the shout circulate among sci-fi fans and Stargate communities, where it is used as a hype sound for dramatic moments. Its brief length and aggressive delivery keep it popular in edits, gaming montages and convention videos long after the series ended.
