• This ability comes from the Powerwild Heartless's Enemy Card. Sora can obtain the Powerwild Enemy card and then use it anytime, whereas Riku automatically obtains the card upon entering Olympus Coliseum, however he can only use it there.
• The Black Fungus enemy card can randomly activate Retrograde.
• The Darkside enemy card can mimic an enemy's Retrograde.
