A sadist, drug addict, and extraordinarily talented holographic illusionist who can project photorealistic hallucinations directly into the minds of anyone around him. Riviera is one of the most genuinely disturbing characters in the Sprawl trilogy - charming, beautiful, and completely without conscience, using his abilities to enact cruelty as a form of aesthetic expression. He is recruited by Armitage for the Neuromancer job specifically because Tessier-Ashpool's 3Jane finds him fascinating. His talent for making people see what he wants them to see makes him useful and extremely dangerous.
