5 years later, Korrina's hair is noticeably longer, and she wears it into a bun and a ring, resembling the Mega Evolution symbol. She first appears wearing a thick white full-body coat, before she takes it off and reveals her current outfit: a zipper crop top with a tall collar, double-layered shorts, and a bandana, all of which are colored in various hues of yellow, green, blue, and purple. Her bandana has the Mega Evolution sigil printed on it. Korrina also wears white arm-length gloves and white boots with yellow-green laces and soles. Her boots have rollerskate wheels embedded in the soles, though they are much less noticeable than her previous appearance.

As part of her goal to master Mega Evolution, Korrina carries many Mega Stones on her person, embedding them in bandolier-like straps that wrap around her torso and waist. Like her Pokémon X and Y appearance, Korrina still embeds her Key Stone on the back of her left glove.
