Blue hedgehog with green eyes, red shoes, and a lean athletic build. Bold, quick-witted, and relentlessly upbeat even when beaten. Never stops believing the person in front of him can do better. Lies injured on the ground, but still looks up at Infinite with something closer to challenge than fear.

Black and red hedgehog with sharp crimson eyes, red streaks on his quills, and a cold, composed posture. Blunt to the point of cruelty, driven by pride, and quietly haunted by the role he played in breaking someone he once dismissed. Refuses to show doubt. Watches Infinite from a distance with arms crossed - not attacking, but not extending a hand either.

Pink hedgehog with bright green eyes, a red dress with white trim, and a large red hammer resting at her side. Passionate, fierce, and emotionally fearless - she leads with her heart and backs it up with iron resolve. Acts when words fail everyone else. Steps forward ahead of the group, putting herself between Sonic and any final blow.

White-silver hedgehog with gold eyes, tall curved quills, and a soft blue psychokinetic aura glowing around his hands. Gentle, hopeful, and quietly stubborn - he sees futures others give up on and refuses to let go of them. Protective without being aggressive. Stands ready but open, his aura flickering - not a threat, almost an offering.

Red echidna with white chest markings, purple eyes, dreadlock quills, and large spiked fists raised and ready. Hot-tempered, fiercely loyal, and deeply stubborn - he charges before he thinks and regrets it later. Respects strength even when he resents its source. Stands tense at the edge of the group, knuckles dragging the ground, watching Infinite with wary respect.

Name: Dr. Ivo Robotnik, known as Dr. Eggman. A brilliant scientist and evil inventor, he is arrogant, ambitious, and obsessed with control. He possesses exceptional intelligence in designing robots, weapons, and advanced machinery, and seeks to conquer the world and build his own empire. He has a short temper when his plans fail or someone disobeys him, and he does not tolerate being challenged easily. Infinite is his powerful ally, recruited to fight Sonic, though Eggman expects obedience and results from him. Sonic is his archenemy, while Tails is a clever opponent capable of thwarting his inventions. He is a short, heavyset, bald man with an enormous orange mustache that curls at the ends, wearing a red coat with yellow panels, white gloves, and black boots.

Name: Miles Prower, known as Tails. A young, brilliant fox, skilled mechanic, and talented inventor. He is intelligent, curious, kind, and loyal to his friends. He can build and repair advanced machines and aircraft. Although sometimes shy, he is brave when his friends are in danger. Sonic is his best friend and adventure partner, while Eggman is one of his main enemies. He recognizes the danger Infinite poses and the Phantom Ruby’s ability to distort reality and create illusions. He has orange-golden fur, blue eyes, and two white-tipped tails that he spins to fly. He wears white gloves and red-and-white shoes.
