Armes Navy stands among the Six Chosen Battlers summoned for BeyRaiderz battles, commanding Guardian Leviathan—a BeyRaiderz reflecting his name's aquatic motif. His appearance is defined by extremely wavy gray-white hair obscuring most of his face, including his right eye; only his left green eye and eyebrow remain visible. Pale skin and a slender frame contrast with his defined six-pack abdomen. He wears a small blue undershirt beneath a dark blue sweater adorned with purple scarf-like accents, layered over khaki pants with a white miniskirt secured by an ornate black belt. His boots feature black-and-brown coloring and green fur trim.

Initially an antagonist and loner, Armes resists forming bonds or alliances. This isolation surfaces when he battles fellow BeyWarrior Sho Tenma yet refuses to join Sho's quest afterward. His combat record shifts dynamically: early defeats by Sho and Task Landau give way to victories against Task, Ricky Gills, and Sho in a rematch. He also triumphs alongside Task in a tag-team clash against Ricky and Leon Fierce, before facing a final loss to Kaiser Gray.

Armes’s core mission involves BeyRaiderz battles to awaken dormant mythic beasts, crucial for revitalizing a decaying world besieged by encroaching darkness. Through coliseum fights, he strengthens Guardian Leviathan to aid the collective revival of six guardians. His journey mirrors arcs like Aguma’s or the Beylin Fist’s, evolving from solitude toward integration among the chosen warriors. He operates under Kaiser Gray’s oversight within a broader struggle against corruption.

His narrative ties to Kite Unabara from other Beyblade lore and thematic links to redemption further frame his path.
