This is an Illustrious style lora for the character Ultron from Marvel Comics. Specifically the look of Ultron 1 - 7 from the 1968 to 1970s. I left out his first look when he looked like a large cylinder and his time as Red Cowl.
A weight of 0.85 to 1.35 works well with this with most models. Sampling Steps of 15 to 35 works well with most models, as does a CFG Scale of 5 to 7.
Prompts for this lora are ( Ultron 1st Era, muscular, robot, )
