Legion introduces the story of David Haller: Since he was a teenager, David has struggled with mental illness. Diagnosed as schizophrenic, David has been in and out of psychiatric hospitals for years. But after a strange encounter with a fellow patient, he's confronted with the possibility that the voices he hears and the visions he sees might be real. He's based on the Marvel comics character Legion, the son of X-Men founder Charles Xavier (played by Patrick Stewart and James McAvoy in the films), first introduced in 1985.

Milo Murphy is the personification of Murphy's Law where anything that can go wrong will go wrong. Suffering from Extreme Hereditary Murphy's Law condition (EHML), Milo always looks to make the best of the cards he's been dealt and his endless optimism and enthusiasm can turn any catastrophe into a wild adventure. Together, he and his friends will learn that it's all about a positive attitude and not to sweat the big stuff... and it's all big stuff.

New Zealand musicians Bret and Jemaine are trying to make it big in New York City, despite their inept band manager Murray, and their sole fan/stalker Mel. Their other friends include Dave, who owns a pawn shop, and Eugene, their building's super. They often break into comedic songs.
