Synopsis

So much for stealth: Sonic trips an alarm within seconds, and the city’s hypnotised citizens chase him and Tails into a dead end, where Bolts’ stretchy arms yank them down a chute to the Robot Resistance, led by Mighton. Lead walls shield the rebels from the signal but keep them indoors, so the immune Sonic and Tails head for the Central Power Core.
Lost among identical streets, they let the guards capture them and deliver them there. The mastermind is Hypnobot, Tails’ old Robot Battle Royale entry, blasted into space and forgotten. Rescued and upgraded by the city’s robots, he gained a mind and a grudge, hypnotised his rescuers and turned the world’s robots against all living things. At home, Knuckles rallies the villagers to defend their stuff.
Tails can’t bring himself to shoot his own creation, and a fumbled shot holes the city’s dome. He tumbles out, his tails bound by a bola, and Sonic, his leg badly hurt, kicks Hypnobot over the edge and grabs his friend. Hypnobot’s plunge into a frozen lake breaks the spell everywhere, leaving Tails with the guilt and Eggman with a frozen new recruit to fish out of the ice.
