This is an Illustrious style lora for the character Ultron from Marvel Comics. Specifically the look of Ultron from Ultron 15 till the Phalanx arc. This can also be known as the third era, yet it was a rather short one as it lasted only a part of the 90s. It is largely marked by Ultron forming his own nation.
A weight of 1 to 1.5 works well with this with most models with best results around or near 1.35. Sampling Steps of 15 to 35 works well with most models, as does a CFG Scale of 3.5 to 7.
Prompts for this lora are ( Ultron Unlimited, muscular, robot, ).
