#0 – Sid Wilson (Turntables) Age during Iowa era: 24–26 (Born Jan 20, 1977) Mask Design: Shifted away from his earlier gas masks to a sleek, dark Skull Mask. Made of light material, it allowed him to move quickly and jump off high stage gear. Persona & Vibe: Unhinged and hyperactive. Sid was famous for diving off balconies into the crowd, stage-surfing, and engaging in physical brawls on stage with Crahan (#6).

#1 – Joey Jordison (Drums) Age during Iowa era: 26–28 (Born Apr 26, 1975) Mask Design: Modified his classic white Kabuki Mask by adding harsh black paint stripes and bloody accents across the forehead and cheeks, giving it an eerie, cold appearance. Persona & Vibe: Hyper-focused, intensely driven, and quiet offstage, but a absolute powerhouse behind the drum kit, driving the band's relentless tempo

#2 – Paul Gray (Bass) Age during Iowa era: 29–31 (Born Apr 8, 1972) Mask Design: A dark grey/black Pig Mask with a vinyl/leather finish, a metal staple across the mouth, and large eye holes. Persona & Vibe: Offstage, Paul was often the warm, glue-like presence holding the band together creatively; onstage, he was a heavy, relentless performer.

#3 – Chris Fehn (Custom Percussion / Backing Vocals) Age during Iowa era: 28–30 (Born Feb 24, 1973) Mask Design: A leather Pinocchio-style Mask featuring a prominent 7-inch nose, a full mouth zipper, and a dark metallic or reddish-brown tint. Persona & Vibe: Energetic and comical yet sinister on stage, frequently mocking the crowd, stroking his mask's nose, and pounding on his custom percussion rigs.

#4 – Jim Root (Lead / Rhythm Guitar) Age during Iowa era: 29–31 (Born Oct 2, 1971) Mask Design: A white Jester/Harlequin Mask with a black zipper mouth and dark paint around the eyes, replacing the older leather mask he briefly wore previously. Persona & Vibe: Reserved, laid-back, and focused heavily on his guitar work, standing out as one of the tallest members on stage with long, dark hair flowing over the mask.

#5 – Craig "133" Jones (Samples / Media) Age during Iowa era: 29–31 (Born Feb 11, 1972) Mask Design: A dark latex Helmet / Space-Head Mask bristling with long, sharp metal spikes (9 to 12 inches long) sticking out in all directions. Persona & Vibe: Extremely quiet, stoic, and enigmatic. Craig rarely spoke in interviews and remained virtually motionless on stage behind his sampling equipment.

#6 – Shawn "Clown" Crahan (Custom Percussion / Backing Vocals) Age during Iowa era: 31–33 (Born Sep 24, 1969) Mask Design: A gruesome, mutated Dark Clown Mask with a bloody pentagram carved into the forehead, a missing scalp, and visible brain matter at the top. Persona & Vibe: Intimidating, highly aggressive, and artistic. Clown was the visionary behind much of the band's visual identity, frequently destroying his drums and confronting both crowd members and bandmates on stage.

#7 – Mick Thomson (Lead / Rhythm Guitar) Age during Iowa era: 27–29 (Born Nov 3, 1973) Mask Design: A metallic, stern Hockey / Leather-Face Mask with a steel paint job and angled eye slits that gave him a permanent, menacing glare. Persona & Vibe: Imposing, intense, and intense. Mick kept interactions brief, focusing entirely on fast, heavy riffing while standing ground like an immovable wall.

#8 – Corey Taylor (Lead Vocals) Age during Iowa era: 27–29 (Born Dec 8, 1973) Mask Design: A heavily distressed, pale Leather / Crash-Test Mask with long dreadlocks pulled through the top. Over the tour, he cut his own real hair shorter, leaving the dreadlocks hanging loosely off the mask. Persona & Vibe: Raw, angry, and emotionally volatile. Corey pushed his vocal cords to absolute limits every night, channeling personal anger and physical pain directly into his performances.
