Smoke Hat

Smoke debuted in Mortal Kombat II as an unplayable hidden character who randomly appeared at the start of a match and dropped vague clues on how to find and fight him, for which specific requirements had to be met by players. He moved with increased speed and used Scorpion's spear attack, all while gray smoke continuously emanated from his body. He was selectable in MK3 after being unlocked by players, and given a backstory of being a Lin Kuei assassin alongside the younger Sub-Zero, but after the clan transforms their best warriors into cyborgs (including Cyrax and Sektor), Smoke and Sub-Zero refused to take part and defected.
