In 'Snow Crash' by Neal Stephenson, what is the name of the protagonist?

In Neal Stephenson’s Snow Crash, the protagonist is Hiro Protagonist.

Hiro is a freelance hacker, skilled swordsman, and pizza-delivery driver working for the Mafia in a fragmented future version of Los Angeles. The name is deliberately playful: “Hiro Protagonist” sounds like “hero protagonist,” making the character’s narrative role part of his identity. He is also connected to the Metaverse, the novel’s immersive virtual-reality environment.

After Hiro’s hacker friend Da5id is harmed by a mysterious digital file called Snow Crash, Hiro begins investigating the phenomenon. His research links the virus to ancient Sumerian language, religion, neurolinguistics, and a plan involving the media magnate L. Bob Rife. Hiro’s investigation intersects with the work of Y.T., a teenage skateboard courier who becomes his partner in gathering information.

Da5id, Raven, and Y.T. are important characters but are not the protagonist. Da5id is a fellow hacker, Raven is a dangerous and highly capable antagonist, and Y.T. is a major viewpoint character whose independent actions drive much of the plot. Published in 1992, the novel helped popularize ideas about virtual worlds and remains a landmark of cyberpunk fiction.
