Sorry if the poster looks weird, since I edited on CapCut, there wasn’t any other poster with them together, but this idea has been in my head for a while, and I was like, why not put my favorite character worlds together? I always wonder what the Guardians would be like if they met Sonic and his crew members. You can add more members to the team or be apart of the Guardians team. It’s up to you: be a human hedgehog or a totally different creature. Go for it! 

This is a crossover with Guardians of the Galaxy and Sonic the Hedgehog. You can choose to be a part of the Guardians or join Sonic’s team!

Rocket stared intently at his device, tapping the screen. “Hmm, everything seems to be in check... Wait, something’s happening!” he shouted, his eyes widening. “Quill! Quill, a portal is opening up on Knowhere! Get your butt down here!”

Peter activated his jet boots, flying up and landing heavily right in front of the swirling vortex. Drax blinked, bracing himself for a massive, universe-ending threat.

Instead, out tumbled a yellow fox and a blue hedgehog.

Shadow stepped forward, crossing his arms as he looked around the gritty space station. “Something tells me we aren’t in Green Hills anymore.”

Gamora immediately drew her weapon, her eyes narrowing. “Speak up now, or you’re going straight to the Nova Corps.”

Tails’ ears flattened against his head. This world didn’t look colorful or bright; it looked dark and terrifying. Trembling, he quickly darted behind Sonic to hide.

Mantis clapped her hands together, her eyes lighting up. “Aww, the yellow fox is so cute! Let’s keep him!”

Tails’ eyes widened in pure horror. “Keep?...” he whispered quietly to himself.

Rocket raised his heavy blaster, the weapon hummed with gathering energy as he locked his gaze onto Shadow. For some reason, he instantly took a dislike to the dark hedgehog's brooding attitude.

"Let me kill him, Quill! Let me blow 'em up into bolts!" Rocket snarled, his finger itching on the trigger.

Peter immediately stepped in front of Rocket's gun, waving his hands frantically. "Woah, woah! No, Rocket, put the blaster down! Let them talk first."

Peter turned his attention to the newcomers, lowering his posture to look a bit less threatening, though his hand stayed near his own element guns. He looked from Shadow to Sonic, and finally to the trembling Tails.

"Where did you guys show up from?" Peter asked, his voice echoing in the metallic hangar of Knowhere.
