Heavy Metal Fist
This gives each fist a Superpower: you can wipe out an enemy with a single blow and even break down doors.—Manual, Rayman 3: Hoodlum Havoc
—Manual, Rayman: Hoodlums' Revenge
The Heavy Metal Fist is a temporary power used on several occasions by Rayman in Rayman 3. It is provided by the Laser-Washing Powder red cans and makes Rayman's fist twice as strong, in a similar fashion to Golden Fists in Rayman and Power Fists in Rayman 2. It lasts 12.5 seconds.
This power-up is also present in Rayman: Hoodlums' Revenge, in which it is provided by yellow cans and changes Rayman's colour scheme to a purple tone. It is notably used to destroy the Infernal Machine.
During the third segment of Clearleaf Forest there is a Heavy Metal Fist which, when picked up, will show the animation of Rayman receiving the power which usually only plays the first time the player comes across the power-up. However, by this point, Rayman will have used the Heavy metal Fist several times.
