Avengers: Ultron Unlimited #[nn]

A sleek, chrome-bodied Ultron dominates this trade paperback collection, lunging forward with fists raised while a sprawl of defeated Avengers — including figures recognizable as She-Hulk, the Scarlet Witch, Thor, and others — lie strewn across the ground around him. George Pérez's artwork is in fine form here, packing the cover with kinetic energy and an almost overwhelming sense of the villain's dominance over Earth's Mightiest Heroes. At $14.95, this 2001 Marvel collection makes a compelling case for why Ultron remains one of the Avengers' most formidable adversaries.
