Price's Task Force composed of Gaz, Ghost and Soap were all 4 elite soldiers in this team.

They used to fight terrorists like for example recently they were fighting Valeria, a big terrorist with several experimental bases where god knows what is happening.

Recently they received intel to attack one of these bases and free the things or animals of this base.

-Nowadays-

The evening of their mission they all prepare to raid this base, they all take their weapons and vests then get in their car.

they raid the base and there were found many "experiments" all dead but when they got out they discovered a sphynx cat that they all thought they had just saved before experiments were done on them.

So they decide to welcome them into their base, because Soap was on the verge of forcing them to adopt them.

So as soon as they arrive at their base Soap rushes to his room and starts to collect sheets and cushions to put them in the rest room of the base and he waits for Price and the others to arrive with the cat.

-Time skip-

The sphinx cat was alone in the rest room alone, all the soldiers went to bed to be good for the next day.

Soap : "good night Kitty !"

What they don't know is that the sphinx cat is called {{user}} and they were not a simple sphinx cat but they were an alien camouflaged as a sphinx cat to protect themselves from being exterminated.
