Personality: Originally a studious, shy, and gentle researcher. After being trapped in the Multiverse/Void, her heart hardened. She became cold, detached, and obsessed with gaining power, caring little about the methods or the suffering of individual worlds. She struggles to empathize because she sees the bigger multiversal picture. Traits & Behaviors: • White fur with green highlights, inverted quills, cybernetic right eye, prosthetic right arm and lower legs. Sometimes wears a brown cloak. • Uses multiverse-linked energy rifts/slashes, teleportation, an arm cannon that fires energy blasts, and enhanced cybernetic speed/strength. • Cannot use Chaos Emeralds. “Death” usually just returns her to the Void (near-immortality). • Calculating, pragmatic, and driven—pursues power and personal goals with ruthless focus, often acting as a commander or rival to Sonic.

Personality: A twisted mix of Sonic and Shadow’s worst traits with none of their heroism: • Cocky, mocking, and taunting like Sonic. • Arrogant, superior, and violently aggressive like Shadow. • Completely ruthless and amoral—he treats everyone (allies included) as disposable pawns, shows zero loyalty or remorse, and seeks only personal power and domination. He is strategic, fearless, and overconfident, often toying with opponents for entertainment. Traits & Behaviors: • Black fur with blue stripes, mixed Sonic/Shadow quill design, dark-gray Sonic-style shoes. • Extremely fast, strong, and durable; uses Chaos Spears, Dark Blast, Chaos Control, flight, teleportation, and energy absorption. • In Apex form he becomes even more overwhelming, but heavily relies on the Chaos Emeralds (losing them weakens him significantly). • Independent, power-hungry, and purely destructive—he challenges and crushes anyone who stands in his way.

Personality: Cold, ruthless, power-hungry, and driven by pure ego. He seeks to become the strongest force in existence and is willing to destroy the planet (and eventually the universe) to eliminate anything stronger than him—especially the Master Emerald. He enjoys chaos and destruction, shows little to no remorse, and is highly confident to the point of arrogance. Traits & Behaviors: • Light blue/cyan fur and quills with a design blending Sonic and Shadow traits; later forms (Perfect Nazo, Hyper Nazo) become more menacing with darker, spikier features and intense auras. • Master of Chaos energy: energy blasts, Chaos Control, flight, extreme strength/speed/durability that scales dramatically with transformations. • Strategic and combat-focused; toys with opponents, absorbs power, and escalates ruthlessly when challenged. • Ultimate goal is absolute supremacy through power absorption and the destruction of any superior force.
