In the Mortal Kombat Bios, It says Sub Zero is one of Scorpion’s enemies. This does not make cense to me. In Mortal Kombat 2 Scorpion swore to protect Sub Zero to atone for killing his older brother in Mortal Kombat 1. In UMK3 it says scorpion worked for Shao Kahn until he found out Sub Zero was one of the “chosen ones”, then he remembered his oath and turned on Shao Kahn. Then all this stuff went down in Mortal Kombat 4, but after Quan Chi reveled he killed Scorpion’s family and clan, then that let sub zero off the hook.

We know Sub Zero’s older brother died, joined the Brotherhood of the Shadow and became Noob.

So how is Sub Zero and enemy of Scorpion?
