Event Pokemon Zeraora + Battle Ready Event Shiny Zeraora. The original Zeraora comes from the Fula City event in Pokemon Sun and Moon. The Shiny Zeraora was obtained in Pokemon Home after a contest in Pokemon Sword-Shield.
They're both legitimate fully leveled Pokemon that can be sent to either your Pokemon Sword-Shield or Pokemon Home account.
