Scorpion is a character in the Mortal Kombat fighting game franchise by Midway Games and NetherRealm Studios. A ninja dressed in yellow, his primary weapon is a kunai rope dart, which he uses to harpoon opponents. Since his debut in the original 1992 game, Scorpion has appeared as a playable character in every main installment except Mortal Kombat 3 (1995).

The series' original Scorpion is Hanzo Hasashi (Japanese: 波佐志 半蔵), an undead Japanese warrior principally defined by his quest to avenge the deaths of himself, his family, and his clan. After killing Bi-Han / Sub-Zero, whom he believed to be the killer, Hasashi develops a feud with Bi-Han's younger brother and second Sub-Zero, Kuai Liang, that spans most of the franchise before discovering Quan Chi is the real murderer. While Hasashi has been depicted as a neutral figure focused primarily on seeking revenge, he will side with those who can help him achieve his goals. Following two reboots, Kuai Liang (Chinese: 奎凉; pinyin: Kúi Liáng) becomes the new Scorpion in Mortal Kombat 1 (2023), while alternate timeline variants of Hasashi make minor appearances. Scorpion has received critical acclaim since his debut and frequently appears in media outside of the games.
