The Koichi Pose originates from the manga and anime series JoJo's Bizarre Adventure: Diamond is Unbreakable, specifically featuring the character Koichi Hirose on the volume 28 cover art. The pose depicts Koichi standing with his legs spread and arms slightly out, projecting a peculiar aura of confidence and awkwardness simultaneously. It became a viral sensation in the late 2010s, often compared to the T-pose or other dominance-asserting stances. Fans use the template to humorously suggest that a character or person is unexpectedly powerful or intimidating, often Photoshopping Koichi into various unlikely scenarios or recreating the pose in real life to capture its bizarre energy.
