I knew I wanted an appropriately scaled movie Ultron figure (his mk.3 form is about 7 feet tall) for the 3 3/4 Marvel figures. I just hadn't seen the right base body out in the world--until I saw the Power Rangers line. I chose the Black Ranger solely because the base color lent itself to the figure. I sculpted the chest details and the leg details and used the head from the Disney Infinity Ultron figure because it was perfect.
