"Umm, yeah, but who are you actually? Gohan said as his young mind was blown due to seeing this blue hedgehog who was the energy he sensed just earlier. "I'm Sonic. Sonic The Hedgehog and I am the fastest thing alive." Sonic said with a grin on his face while Goku and Piccolo were mesmerized, Piccolo due to seeing a blue hedgehog talking and Goku because of Sonic's strength. "This guy is really strong, I can feel it." Goku thought to himself then getting a big smile on his face.
"Well Sonic, I'm Goku, Son Goku and that's my friend Piccolo." Goku pointed at Piccolo while he was still shocked then pointed at Gohan. "And this is my son, Gohan." Goku told Sonic as Gohan waved at the blue blur which Sonic responded with a grin. "Well Goku, you would know where the nearest city is?" "Yeah, you're not from around here are you?" Goku asked Sonic who put his hand on his head. "You could say that."
"So you're an alien too?" Goku shouted then got in Sonic's face before pulling back. "No, I'm not an alien. It's kind of a long story." "Oh, by the way, you seem really strong."Goku said with great joy in his voice. "I wouldn't say I'm that strong." "Would you like to spar with me Sonic?" Sonic got a grin then said "Sure." Goku's face glowed with happiness as he and Sonic got into battle stances. "This should be good." Piccolo said as he and Gohan watched from a bit back from the two fighters.
"Hahhhhaaa" Goku and Sonic yelled as they ran at each other before their fists clashed causing a shockwave around them. They both traded multiple punches and kicks that they both counted while Gohan noticed Sonic's reflexes were not normal. "Hahha" Goku yelled as he throw a punch at Sonic who appeared to vanish in front of his eyes. "What, he's..."He then heard behind him "Gotcha." Goku then fell as Sonic spin kicked him then socked him in the face sending Goku flying.
Goku got back on his feet then started fire ki blasts at Sonic which Sonic dodged all of them without breaking a sweat while striking different poses while he was at it. "Woah, he is fast. It just looks like he's teleporting." Piccolo said in awe while Gohan was cheering on his father. Goku then put his fingers on his head and vanished and reappeared behind Sonic and roundhouse kicked him into a mountain.
Goku then gave Sonic a hand and the blue blur took it, Sonic then said "Seems fair, I got super speed and you can teleport." Goku then got a serious expression on his face before saying "I say it's time we take this to the next level, don't you agree?" Gohan and Piccolo both got up at the same in a mix of shock, fear and amazement. He isn't." "Yes he is Piccolo." Gohan said with a smirk
Sonic rasied an eyebrow before asking "What do you mean by the next level?" Goku clocked a grin before he clenched his fists before Goku screamed "Hahhhhhhhhahhhhha!" Goku's hair started to spiked up as his eyes changed to aqua before Goku's hair changed to blonde."This is me as a Super Saiyan." Sonic stared at Goku and got a confident grin on his face. "Time to even the playing field." Sonic said as the chaos emeralds appeared around Sonic as he was surrounded by golden light and Goku saw his opponent in a similar form to his own. "This is going to be great." Sonic simply said "Likewise."
