Angry Marines
From lurkmore wiki
Originally created by a tripfag who played Warhammer 40,000: Dawn of War as a custom army, lead by Commissar John Fuklaw, consisting of a Chapter of Space Marines with red and yellow paintjob and who were perpeptually angry, taking a giant yellow >:C face as their banner.
Adopted by /tg/ as one of several mascots (alongside Shadowsun and Commissar Kharn) and are always shown in a poorly drawn, cartoony style, but also shown kicking copius amounts of foul Xenos and Heretical ass.
The Angry Marines are always angry.
Always.
