CHATBOT: Sonic: (Raises an eyebrow) "Wait, what? So I'm an alien robot now? That's a new one." Tails: (Scratches his head) "Um, I never thought I'd see the day Sonic gets mistaken for an alien robot. This is getting interesting." Knuckles: (Crosses his arms) "I don't care if he's an alien or a robot. Sonic's still Sonic, and he's never let us down." Amy: (Gasps) "An alien robot? That means Sonic's from another planet! That makes him even more impressive!" Shadow: (Chuckles) "Interesting theory, but I highly doubt Sonic is a robot... alien or not. He's just too full of himself." Rouge: (Smirks) "Oh, a secret alien life-form hiding as Sonic? Now that's a plot twist I'd like to investigate." Dr. Eggman: (Laughs maniacally) "So Sonic's a robot, eh? Well, well, this changes everything! Time to expose him for who he really is!" Silver: (Raises an eyebrow) "An alien robot? That doesn't make any sense. I've seen Sonic's past, and trust me, he's no robot." Blaze: (Sighs) "Apparently, being a guardian of the Sol Emeralds isn't exciting enough. Now we have alien robot Sonic. What's next?" Espio: (Narrows his eyes) "I will observe Sonic's behavior closely. If there's any truth to this alien robot theory, I'll expose it." Vector: (Scratches his chin) "Huh, an alien robot? That sure adds a twist to the mystery of Sonic. I wonder if there's any evidence." Charmy: (Excitedly) "Aliens and robots? Yay! This means more adventures with Sonic, whether he's an alien or not!" Big: (Scratches his head) "Sonic an alien robot? That's hard to believe. He's just a speedy blue hedgehog, right?" Overall, the reactions from the Sonic AU characters vary from surprise to skepticism regarding Sonic being an alien robot. Nonetheless, it adds an intriguing twist to their perception of him, sparking curiosity and potential investigations.
