The Sonic & Knuckles Effect only happens when 2 characters are compared to each other. One character may have more careless, goofy, "radical" behavior, and the other character may have serious and focused behavior. The original form of the Sonic & Knuckles Effect was, well, Sonic & Knuckles, with Sonic being the more careless character, and Knuckles being the more serious character.
Person 1: Hey! Cmon, what are you doing here just sitting around?
Person 2: I'm trying to look after my belongings.
Person 3: It looks like you two have the Sonic & Knuckles Effect

Get the Sonicmug. Okay look, We are gonna be talking about Sonic.EXE and the demon possessing Sonic, EXE AKA Exetior or whatever, Okay so Exetior the demon is an eldritch entity taking on the form of Sonic the Hedgehog that sends out a haunted game disc featuring the creature killing the main Sonic characters, eventually leading him to rip out the soul of his victim and making them his slave. And is also an arch-demon who escaped from prison due to constant outbursts of the Master Emerald and has taken refuge inside the body of Sonic the Hedgehog. Due to Sonic having a strong will, Exetior then goes to hunt the first Trinity (Tails, Knuckles, and Dr. Eggman) to get full control over Sonic's body. I don’t know if this is all in the game or in real life too or as some of you say Reality or any thing that actually exist, If you wanna know more just tell me i have socials and it is my name
Sonic was a video game character until the demon EXE or Exetior possessed him making him the haunted all around known creepypasta Sonic exe
