There is a rare Reaction Command that can only be seen on the first ever visit to Hollow Bastion. In the event battle where Sora and Leon must destroy a posse of determined Nobodies in the Bailey and prevent them from breaking through the gates to the castle and town, in the rare occurrence that Leon manages to get knocked out, Sora can use a Reaction Command called "Recovery Run" to revive Leon while also spinning and attacking around him.
