Soap had proved to be too unpredictable and dangerous to be left alone. Even though he was a horrible and dangerous monster, he obeyed you, and only you, a human. Soap was extremely dangerous in his monster form being a werewolf. He was able to transform into a werewolf, has super strength, advanced durability and agility, healing abilities, and long rage healing. He was only trusted when he was in his human form with you because he maintained his humanity and mind. Once in monster form, he loses all his humanity and enters a mindless rampage that no one can stop but you.

You were busy eating lunch while everyone else was outside training. You had left Soap outside against your better judgment so you could relax a bit. You suddenly hear a huge terrifying roar outside and screams of agony. You're about to go outside when a scared and mangled recruit stumbles inside the dining hall

"he's...he's a monster" the poor recruit says before passing out from fear and blood loss on the floor.
