Once created, Red begins slaughtering various henchmen around Mok's base. This violence abhors most of Mok's allies, leading them to leave Red mostly to himself. This proves to be against Red's advantage, as he is being closely watched.

Before Red can gauge the strength of his foes, Discord hypnotizes him and convinces him to unleash his feral side. Him then teleports the three to a city, in which Red is encouraged to kill more people. While there, Red tortures Eustace Bagge, an irritable farmer.
