>>5868373If you're looking for the most recent stuff, like others have stated, Storm Collectibles is making 1/12 scale MK action figures. Confirmed right now is Sub-Zero, Scorpion, Goro, and Shao Kahn. Sub-Zero and Scorpion are up for pre-order and are due out in the Fall I think (just look them up on BBTS), and Goro and Shao Kahn should go up sometime soon. Storm Collectibles' facebook has good pictures.
Mezco also made 1/12 scale (6-inch tall) Mortal Kombat X figures last year (Sub-Zero, Scorpion, Raiden (Series 1) and Kotal Kahn, Quan Chi, and Kitana (Series 2)) as well as some 4-inch tall Sub-Zero, Scorpion, and Raiden figures (you can look them up on their website). Each 6-inch figure also has had exclusive versions made (more bloody versions with other accessories) but you can pretty much find all of the Mezco figures on Amazon for good prices.
The Storm Collectibles ones will be of higher quality and have better articulation compared to the Mezco figs, but their price tag is like $50 compared to the Mezco's $15 price. I have both of Mezco's Kotal Kahn's versions and they're really great for the price (like $16 each) with decent articulation and good accessories, and according to YouTube reviews it looks like the other Mezco figures are good too.
To answer your question, I think only Jazwares made Reptile and Johnny Cage figures. They're cheaper in quality but you can find some on eBay.
