Jack 5

Jack-5 was created by Jane as an upgrade of Jack-4 and used the fifth tournament as a means of testing Jack-5. Returning to have his emotion program installed, Jane downloads Gun Jack's memories into him, but the results cause him to go berserk, ripping free and trashing the lab. As he brings down his arms in a crushing blow on Jane, the memories re-assert themselves and Jack stops, looking over his body in confusion. Jane goes to him and he picks her up in his arms gently, his original personality fully restored.
