Fatal Kicks: Li Mei kicks her opponent's stomach, lodging her foot in the opponent's innards. She keeps it there for a second before pulling it out, then kicks the oppnent's head, causing it to explode. (MK:DA)
Brutality: Li Mei repeatedly strikes at the torso and head of her opponent very quickly, and then stands, striking a pose. The confused opponent then screams in pain a few seconds later and explodes in a shower of gore. This fatality seems to borrow from the Asian martial arts study of pressure-points. (MK:D)
Head Grenade: Li Mei walks up to her opponent and with one swift uppercut, knocks her foe's head straight into the air. Li Mei patiently waits for it to come back down before she kicks it hard at her opponent. When the head strikes them, they explode into piles of blood and bone. This is done in a different way than Liu Kang's Shaolin Soccer. (MK:D)
Hara-Kiri:Deadly Limbo: Li Mei throws her sword into the air and bends over. The sword falls back down and decapitates her. (MK:D)
Li Mei is rather notable in Mortal Kombat: Deadly Alliance for having four special moves; most characters have only two or three. She retains all these moves in Mortal Kombat: Deception.
She is the only normal character to use the "Baji Quan" fighting style, although created characters can use it in Armageddon.
In Mileena's Deception Ending, Li Mei is shown holding a naginata instead of her weapon in the game, which is the Kunlun Dao. Coincidentally, Li Mei was "severely injured" by a naginata in the Armageddon intro video, by means of Hotaru.
In the character select screen, when Li Mei is locked, she is obviously shown in her alternate costume in her character space.
Li Mei was given a new facial model in Deception. In Deadly Alliance, her eyes were larger with them being brown in colour, as well as having larger lips. This was altered in Deception, with her eyes being smaller and being green in colour, along with her lips being reduced in size. Her alternate costume in Deception uses some parts of her Deadly Alliance face model.
Li Mei might have met Kai at some time during his journey in Outworld because in a rare moment speaking to Li Mei she tells of a dark skinned monk, that might have been him.
Li Mei is described as The Defender of the People of Outworld.
Mortal Kombat: Armageddon
She appears in Konquest Mode attacking Shinnok in the Netherrealm cliffs. When Taven shows up, he fights off Li Mei. It is not made clear whether this was the real Li Mei, or simply a clone Shinnok created to test Taven's strength.
She is the first character to receive a critical wound in the opening Armageddon cinematic, by means of Hotaru.
Mortal Kombat (2011)
During the beginning of Story Mode, her corpse can be seen, still pierced by Hotaru's naginata.
