You mean Raid-tile and Son-tile

:

Raidtile can be found at various rare encounters, while using the Reptile Kode, which is:

First, enter the Game Genie code "656A-47AF". If you're playing a one player game, start as anyone you want. After you beat the person from the 1st match you will start another match, this time against Reptile. You will keep fighting Reptile until you turn off the Game Genie. If you lose a match and allow yourself to not continue, you will watch the computer play a ninja vs. Reptile. Then turn off your Game Genie, and allow yourself to die. Then turn it on at the main screen. Then go to the select screen. Go into 2-player Kombat, and have Sub-Zero vs. Scorpion. Then have player 2 beat player 1 and do NOT kontinue. Player to will fight Reptile as a computer. Then make Player 1 join, Player 2 will be Reptile......


Raidtile has the following moves: spear, freeze (rare), lightning, backwards torpedo, backwards lightning, in-battle fatality, and sometimes even the Shadow Kick!

A strange Genesis glitch, like Raid-Tile, of Sonya, in which she has unique abilities. Player must be player 2, and must face Sonya in an endurance round. Genesis flags must be set to "0, 2, 3, 5, and 6". At the pit bottom, Reptile appears as a strange, green Sonya. A green flame varies Reptile to this anomaly, and the character is able to launch freezing rings, to launch the harpoon at strange angles and directions, her victory pose is a blocking stance, and she can perform the fire breath fatality, as well as a strange, leg grapple decapitation, similar to the spine rip.
