The Happy Person was someone who waved at Blackout, because, hey, he's happy. He is a member of the Happy People, a permanently-happy cult that aims to spread joy across the universe.
He later appeared in Ricochet's ship, along with lots of other insignificant people such as Kranxx, The Guy Who Was Engulfed In Milk, Rhanu, Kihri, the Blackout Destruction Society, and the Savant who first employed Kakamu.
After being killed, he was seen in the UG, where he had become saddened. He made a pact with TGWWEIM to get his happiness back, though only one of them escaped from the UG, and it wasn't him.
