Pantalone, a member of the elite quartet Les Quatre Pionniers, holds the title of ball walker within the enigmatic Midnight Circus. His mechanical form boasts sleek, elongated limbs and a sharply gaunt frame, accentuated by stark white hair, a pronounced nose, and a pointed goatee. He dons an emerald-green jacket, crimson bandages, and four gleaming rings on each finger. Renowned for unparalleled physical might, his primary weapons are his arms, which outmatch even fellow automatons in brute force.

Initially exuding arrogance, Pantalone openly scorns humanity as beneath him, reveling in flaunting his dominance. This hubris shatters after a crushing defeat by Narumi during the Sahara conflict, triggering a psychological collapse. Forced to grapple with his fragility, he reemerges post-resurrection with a subdued, introspective demeanor. His actions thereafter reveal unexpected humility, marking a stark departure from his former hubris.

Tasked with advancing the Midnight Circus’s goal to propagate Zonapha syndrome—a condition rooted in their creator’s ambition to draw laughter from ruler Doll Francine—Pantalone’s loyalty remains tethered to his identity as Francine’s jester. His narrative deepens upon receiving final orders from Eleanor of the Shirogane faction, an event that reawakens his buried longing for joy. This directive briefly ignites a whimsical aspiration: to perform beneath a genuine circus tent alongside Arlecchino, hinting at a flicker of unshackled delight.

His combat prowess includes launching pressurized air blasts from his fingertips, enabling coordinated multi-directional strikes. These abilities, paired with his raw strength, cement his threat as an opponent. Though mechanical, Pantalone displays layered emotional evolution—from pride to humility to transient, earnest delight—mirroring struggles with identity and purpose within his existence.
