O background de Sonic (no universo) é visto em uma edição especial em quadrinhos chamada " The Origin of Sonic "
Em suma, o Sonic já era muito rápido (para um ouriço) quando encontrou pela primeira vez o Dr. Robotnik.
"The fastest hedgehog on the planet"
Robotnik forneceu-lhe " poder sneakers " e permitiu que ele treinasse em seu "giroscópio cinético" , resultando em Sonic sendo capaz de correr em velocidade super-sonora.
A história em quadrinhos em si é uma releitura de um trabalho anterior; O livro licenciado Stay Sonic
Partly out of curiosity, and partly to assist Dr K in his research, Sonic put in several hours a day on a solar-powered treadmill that the Doc had built for him. The treadmill, or Kinetic Gyratosphere™ to give it its patented name, was capable of revolving at high speeds. Sonic protested that it made him feel like a gerbil on steroids. However, when Kintobor developed special friction-reducing trainers for him he became more interested. The cutting edge design and classic red styling hid some state of the art additions including Duratex™ soles with exceptional grip and specially cushioned odourless inners. Covering as much ground at the speeds he did frequently left him with blistered feel. They were also a necessary safety measure because Sonic started to build up the sort of static that could ignite the treadmill or shoot sparks into the lab. Gradually Sonic increased his speed to 200, 400, then 500 mph.
Kintobor torqued up the treadmill every day, pushing it in 20-mile-on-hour increments What hod begun as an idle exercise was developing into a majorly phenomenal experiment Then one day, impossibly. Sonic crossed all known limits of mammalian acceleration and broke the sound barrier The treadmill had been running for thirty-five minutes and he was little more than a blur when suddenly there was an enormous bang and a tremendous wind swept all the papers into the air. Alarmed, Kintobor attempted to slow down the treadmill - stopping it dead would have had disastrous consequences, probably sending Sonic into orbit over Mobius. Eventually he managed to gain control of the machine and gradually reduce Sonic's velocity, but it took nearly an hour to bring it to a stop
When, finally, Sonic stepped breathlessly out of the treadmill he wasn't the same hedgehog that had gone in. His physical appearance had changed dramatically. Instead of his unexceptional, greyish-brown shade., most of Sonic's body had turned brilliant, cobalt blue, on his spikes stood straight back in a stiff mohawk
My word!' exclaimed Kintobor, struggling to comprehend what had just happened I think you've gone blue from the shock waves Not to mention the Cobalt Effect™' he said
You clocked up 761 miles per hour! You've really earned your name now! In fact, I should call you SuperSonic - what do you think of that?' Kintobor cried, dancing around the lab like a demented, er, scientist.
SuperSonic, yeah - radical Cool.' grinned Sonic, examining his glowing blue body proudly in a mirror, but what about getting some food? All that running's made me hungry!'

Still, he knew he'd never be a nerd like Dr. K. So partly for relaxation, and partly for Dr. K's amusement, he logged in several hours a day on the supersonic treadmill that Kintobor had -built for him. Slowly, Sonny built his speed to 200 , 400, then 761 m.p.h. -- the speed of sound. Then, impossibly, he crossed all known limits of acceleration and began running at the speed of light. Alarmed, Kintobor tried to slow the treadmill. Although he managed to gain control of the machine and bring his friend's velocity down slowly, a change had come over Sonny. Instead of his unexceptional, grayish-brown color, most of his body had turned cobalt blue, and his quills stood straight back in a stiff mohawk.
"My word!" exclaimed Kintobor, who struggled to comprehend what had just happened. "1 think you've gone blue from the Advanced Non- Concussive Cobalt Effect!" he said, helping Sonny from the treadmill.
" 186 thousand miles per second! You're so fast, we should call you Sonic. SuperSonic, even. How do like that!" he cried, dancing around the lab like a demented pixie.
