Laughing Octopus (from Metal Gear Solid 4) by Konoe-Lifestream
The girl who became Laughing Octopus was born in the small seaside Scandinavian town known as the Devil’s Village. The primary meat consumed in this village was octopus caught nearby. An anonymous cult nursed a deep hatred for the village. When Laughing Octopus was a young woman, the cult accumulated enough heavy weaponry to launch a deadly overnight assault against the town. The conflict concluded when the cult rounded up the survivors and executed them one by one. However, instead of executing the girl (whom they referred to as “The Devil’s Child”), they forced her to participate in the torture of her family and friends, making her enjoy it all the while by making her laugh. Fearing for her own life, she did as her captors made her and massacred her entire family. Eventually, she began to hallucinate that the blood on her hands turned from red to black, resembling the ink of the octopus which they had loved so.
The incident left her emotionally-scarred and prone to fits of laughter, especially during combat.
