Mordecai: Mordecai would be a cocky, yet ultimately kind-hearted hedgehog. His quills would be a vibrant blue, mirroring his usual attire. He'd retain his laid-back attitude, but his speed and agility would be significantly enhanced, allowing for quick escapes from tricky situations and impressive acrobatic feats. His fighting style would incorporate parkour elements, utilizing his environment to his advantage. He might even have a special move involving a flurry of perfectly aimed quills. His rivalry with Rigby would be amplified by their contrasting personalities and abilities, leading to frequent, high-speed chases across Mobius.

Rigby: Rigby would be a cynical, sarcastic raccoon with a penchant for trouble. His fur would be a dark grey or black, reflecting his mischievous nature. He'd be surprisingly quick and agile, though less refined than Mordecai, relying on brute force and cunning tactics. His fighting style would be more chaotic and less precise, utilizing improvised weapons and dirty tricks. He might have a special ability related to his innate laziness, perhaps slowing down time or creating illusions to escape difficult situations. His constant attempts to slack off would often lead to hilarious consequences, especially when facing powerful enemies.

Benson: Benson would be a stern, authoritative badger, possibly with a robotic arm or other cybernetic enhancements reflecting his managerial role. He'd be less physically agile than Mordecai and Rigby, but possess superior strength and strategic thinking. His fighting style would be methodical and calculated, utilizing his enhanced strength and possibly some kind of energy weapon. He'd be the voice of reason (though often ignored), trying to maintain order amidst the chaos caused by Mordecai and Rigby's antics.

Muscle Man & High Five Ghost: Muscle Man would be a hulking, powerful bear, possibly with a slightly goofy demeanor despite his strength. High Five Ghost would be a spectral entity, perhaps with the ability to phase through objects and possess enemies. Their combined abilities would make them a formidable team, though their lack of coordination could lead to comical mishaps.

Pops: Pops would be a wise, elderly owl, possessing magical abilities and a calm demeanor. He'd be a mentor figure, offering guidance and support to the others. His fighting style would be more defensive and supportive, utilizing magic to heal allies and hinder enemies. He might even have a hidden power, revealed only in times of great need.

Skips: Skips would be a mysterious, enigmatic creature, possibly a wolf or a creature entirely unique to Mobius. He'd possess advanced technology and a vast knowledge of the world, acting as a silent observer and occasional helper. His fighting style would be unpredictable, utilizing a combination of technology and his own unique abilities.

The Park: The park itself would be transformed into a vibrant, sprawling landscape, filled with familiar locations but with a Mobius twist. The familiar trees and buildings would be replaced with fantastical flora and fauna, and the overall aesthetic would be more vibrant and cartoonish, reflecting the Sonic universe's style. The park might even be located near a bustling city or a hidden ancient ruin, adding to the adventure.

The overall tone would be a blend of the quirky humor of Regular Show and the high-octane action of Sonic. The characters' personalities would remain largely intact, but their abilities and the setting would be completely reimagined within the Mobius universe. The resulting scenarios would be filled with fast-paced chases, hilarious misadventures, and unexpected twists, all while retaining the unique charm of both franchises.
