Mortal Kombat II

Mortal Kombat II is an arcade game and the second title in the Mortal Kombat fighting game series. Storywise, it is supposedly preceded by Mortal Kombat: Shaolin Monks, but (in recent times), the canon of that game has come into question, so (for many), Mortal Kombat: Shaolin Monks is not canon to the story of Mortal Kombat II.

Baraka: Tarkatan warlord.
Jax: A member of the Special Forces and a longtime comrade of Sonya Blade, who enters the tournament to rescue her from Shao Kahn.
Kintaro: Shokan warrior, general of Shao Kahn's army, and Goro's successor.
Kitana: Shao Kahn's personal assassin, and step-daughter.
Kung Lao: Shaolin monk and friend of Liu Kang, who seeks to avenge the destruction of the Shaolin Temple.
Mileena: Shao Kahn's personal assassin, and Kitana's clone.
Reptile: Shang Tsung's personal bodyguard.
Shao Kahn: the Emperor of Outworld.

Reptile appeared in the original Mortal Kombat, but this is the first game where he is playable and contains his own moveset.

MKII also contains three hidden unplayable characters. They are incredibly fast and very unbalanced.

Smoke: Sub-Zero's friend, emits puffs of smoke from his body.
Jade: Another Outworld assassin, who cannot be hit by projectiles. Childhood friend and protector of Kitana.
Noob Saibot: Evil dark ninja, a lost warrior from a previous Mortal Kombat.
