I personally think Scorpion would make a great police officer, if anyone tried to run he could just use his spear, or the teleport technique.

Reptile or anyone else who can disappear would get a reputation as a peeping tom and be kicked out of many nightclubs and clothing outlets.

Havik would open a gnarly Halloween store

Johnny Cage would successfully nail every actress on the set(s) of his new movie(s)

Sub-Zero: working inside the freezer in the meat department at your local Deli. What other human could withstand such temperatures during a full time shift?.

Jax: Local club Dj.

Mileena: Stripper with the face mask so she doesn't scare customers with her jaws but allure them with her body.

Frost: hustles ice-pops to the kids in the neighbor hood using gallons of flavored mix, & water, and oh yea.... her powers.

Johnny Cage: currently starring in a new film with Danny Devito, and George Clooney called "Guest Who's Home". In a theater near you(check your local listings, charges may apply).

Stryker O.k. this is a given. Either he would be a cop in everyday life or a swat maniac. Toss a coin. Pick one.

Kitana Tiger Scholman's martial arts instructor.

Bo Rai Chou The fake Santa Clause in your local mall.
