In Rayman 2
Blades return in Rayman Legends; they can be first found in Creepy Castle. These blades act slightly different than they did in Rayman 2, as certain ones will only move when the player steps on a nearby platform mechanism.
Blades also appear in Rayman Adventures where they act like in Rayman Legends. They mainly appear in Toad Story where they are used as an obstacles in several of the ruin themed levels. Just like in Rayman Legends they swing back and forth causing instant death to the player upon contact.
