The butterflies[1] are obstacles that appear in Sonic and the Black Knight. It is a mystical breed of butterflies which can cast illusions.


The butterflies have black bodies and black wings, though their wings gradually change to a purple color.


Butterflies only appear within certain missions in Shrouded Forest. Like the bats, the butterflies can only affect the player when they get near them. When this happens, they surround the playable character and create an illusion, making the player see things that are or are not around, like creating a fake Treasure Chest or disguising a Knight of the Underworld like a Treasure Chest.
