Reptile has always been one of the most unique characters in the Mortal Kombat franchise. Starting as a secret green ninja in the early days, he evolved into a fan-favorite fighter with shapeshifting powers, acid attacks, and stealth-based gameplay. Over the years, his design, lore, and playstyle have gone through major changes — some beloved, some controversial. Let’s take a look at Reptile’s history across the Mortal Kombat series, breaking down his story and gameplay in each major title where he appeared as a playable character.
Mortal Kombat (1992) – Hidden Character
Reptile debuted as the first-ever hidden character in fighting game history. He wasn’t playable, but he could be fought under specific conditions: win two rounds flawlessly, get a Double Flawless against the computer, and perform a Fatality on the Pit stage with a shadow passing the moon. He was essentially a palette swap of Scorpion and Sub-Zero, with both fireball and teleport moves.
Rating: ★★★★☆ (4/5)
As a hidden opponent, he instantly became legendary, setting the standard for secret fighters in fighting games.
Mortal Kombat II (1993) – First Playable Appearance
Reptile became a full-fledged playable fighter in MKII. His story revealed he was part of a dying reptilian race called the Saurians, loyal to Shao Kahn. Gameplay-wise, he gained his acid spit, forceball, and invisibility moves, which would define his playstyle for years.
Rating: ★★★★☆ (4/5)
Unique moves and lore gave him an identity, though he was overshadowed by flashier characters like Kung Lao and Kitana.
Mortal Kombat Trilogy (1996)
Reptile returned with his classic toolkit, plus an expanded move list thanks to Trilogy’s inclusion of nearly every character. He was solid in competitive play, with his forceball setups creating pressure opportunities.
Rating: ★★★★☆ (4/5)
A strong, balanced version of Reptile that long-time fans loved.
Mortal Kombat 4 / Gold (1997–1999)
In MK4, Reptile was redesigned with a more lizard-like appearance. His moveset stayed consistent, but the 3D engine gave him new animations. Story-wise, he served Shinnok, still clinging to his loyalty to powerful masters.
Rating: ★★★☆☆ (3/5)
Fans were divided on his look (personally I absolutely hated it), and gameplay wasn’t as impactful compared to past entries.
Mortal Kombat: Deadly Alliance (2002)
Deadly Alliance leaned fully into Reptile’s saurian heritage, giving him a full reptilian monster design. He used martial arts styles (Hung Gar, Crab, and Kori Blade) alongside his classic acid spit. In the story, he became the host for Onaga, the Dragon King, a pivotal moment in MK lore.
Rating: ★★★☆☆ (3/5)
Cool story role, but many players disliked the drastic design change. This was his worst design ever IMO.
Mortal Kombat: Deception (2004)
Though Onaga (Dragon King) was playable, Reptile in his traditional form wasn’t directly available. His essence lived on through Onaga, meaning Reptile himself sat out of the playable roster.
Rating: ★★☆☆☆ (2/5)
Important for the lore, but fans missed Reptile as a standalone character.
Mortal Kombat: Armageddon (2006)
Reptile returned with his monstrous saurian look from Deadly Alliance. He had access to every character’s Fatality through the new Kreate-a-Fatality system.
Rating: ★★★☆☆ (3/5)
Playable again, but the universal fatality system made him feel less unique.
Mortal Kombat (2011) – MK9
Reptile came back strong in the Mortal Kombat reboot. He had his classic ninja look with reptilian features. His gameplay was fast, with zoning tools like the forceball and strong mix-ups thanks to his dash and invisibility. In the story, he remained Shao Kahn’s loyal servant.
Rating: ★★★★★ (5/5)
One of his best versions, competitively viable and true to his roots. Just might be the best reptile we will ever see!
Mortal Kombat X (2015)
Reptile received a new design, leaning into his saurian background but keeping a ninja-like silhouette. His variations (Deceptive, Noxious, Nimble) gave him flexibility — from invisibility to poison gas. His story role was minor, once again playing the servant role.
Rating: ★★★★☆ (4/5)
Strong gameplay variety and unique mechanics made him stand out.
Mortal Kombat 11 (2019)
Reptile didn’t make the base roster in MK11, but he appeared in the Krypt as an NPC who could be found hiding in secret passages. Fans were disappointed by his absence as a playable character.
Rating: ★★☆☆☆ (2/5)
Cool cameo, but fans wanted him on the roster.
Mortal Kombat 1 (2023)
Reptile returned in MK1 with a major redesign. He could now shift between human and reptilian form, which tied directly into his gameplay. His moveset included classic acid attacks and new shapeshifting tricks. Story-wise, Reptile’s struggle as an outcast was fleshed out, making him one of the most relatable versions yet.
Rating: ★★★★★ (5/5)
A triumphant comeback with depth in both lore and gameplay.
WE LOVE REPTILE
From hidden ninja to saurian shapeshifter, Reptile has gone through one of the most dramatic evolutions in Mortal Kombat history. While some versions were divisive, his best appearances — MKII, MK9, and MK1 — cement him as a fan-favorite. His mix of speed, stealth, and acid-based attacks make him a character that truly stands out in the Mortal Kombat universe.
Overall Reptile Rating Across Games: 4/5
