• Thunder God Island & First Hunts: Traveling with Borsalino, Mobius requested to be dropped off at Thunder God Island, where he transformed into a red dragon and tempered his body in the thunderclouds 3 4 5.

He also absorbed multiple Zoan fruits, creating fused combat states like the Chimera and Suanni forms 9 10.
• Fish-Man Island National Advisor: Traveling to Fish-Man Island, Mobius met the fortune-teller Shyarly, sparred with Jinbe, and helped protect the kingdom 13 16 19.

Appearance

Mobius is not described as conventionally handsome; his appearance is prematurely aged and somewhat lecherous, yet he carries a powerful, extraordinary aura 1. In his dragon-form or transformed states, he can manifest crimson dragon scales, horns, multiple heads (in Chimera form), or a smoke-and-fire-infused Suanni body 4 9 26.

• Can transform into various mythical and zoan states (Red Dragon, Flood Dragon, Chimera, Suanni, Taotie) 4 9 10.
• Capable of healing severe injuries almost instantly due to integrated salamander regeneration 26.

Personality

Mobius is ambitious, strategic, and openly driven by a desire for power and influence, remarking that a soldier without the ambition to become fleet admiral or king is no different from a salted fish 1. Despite his high-reaching and calculating nature, he maintains a strong conscience, cares deeply for his mentors (Vegapunk and Borsalino), and takes responsibility for collateral damage caused by his training 1 9. He is calm under pressure, maintains a cheerful or teasing demeanor with friends, and shows no mercy toward hostile pirates 3 8 30.
