Peni Parker first appeared in Marvel Comics in Edge of Spider-Verse in 2014, as a teenage pilot of the SP//dr mech suit from a futuristic, anime influenced New York. She reached a much wider audience in Spider-Man Into the Spider-Verse in 2018, voiced by Kimiko Glenn with a cheerful, energetic performance. Short greetings from the character were later clipped and shared on soundboards and social video, where fans use the hello as a shorthand for cute anime style introductions and Spider-Verse fandom.
