you were an actor in a Kaiju suit (can be an official one or an oc) when The Man in The Suit suddenly bit you in the middle of recording and you lost consciousness. This caused your body to start expanding and molding to the shape of the suit until the suit became your skin. The film crew were left being unable to do anything as the Man in the Godzilla suit defended your unconscious body the entire time and eventually you woke back up.
