Sonic & Johnny


Sonic & Johnny is a heavy modification of Sonic the Hedgehog by Lone Devil where the goal is Racing against your Rival for the first Two Acts while fighting New Bosses along the way. Featuring Johnny from Sonic Rush Adventure and New Zones containing plenty of familiarity.


After Robotnik’s disatisfaction with his rebellious Metal Sonic, Robotnik and his empire decided to own land, and reclaim all the Chaos Emeralds to mysteriously summon an individual from another dimension who calls himself Johnny. After being sold with Johnny’s arrogant skills, Robotnik constructs a deal that would give Johnny the fame and recognition he always wanted by inviting him to his recently funded Atomic Stadium, an small island built for the strongest of racers with a special prize if one of the racers collects all Emeralds.

Sonic gets a report from Knuckles that his Emeralds is missing and later received a letter from Robotnik threatening Sonic to join his 1v1 Grand Prix or else one of his friends will remain kidnapped forever. Sonic calls Tails to fly him to the nearest stadium to join the race to beat Robotnik’s latest successor to Metal Sonic and find out what’s really going on.


  • SONIC – Can’t fix what isn’t broken because hes Sonic! One difference is he accelerates instantly as soon as the maximum Spindash button count hits. His Shield Ability is a powerful Dropdash.
  • JOHNNY – The Sultan of Speed on his quest to prove to the crowd that no one is faster than him. Since he can’t willingly Roll like Sonic, His invulnerability lies in his speed like a torpedo. Johnny can stomp on enemies and itemboxes, Charge a Super Peelout (↑+A) that can be cancelled for a quickdash, Slide (hold ↓ while moving) and SuperJump (↓+A) to reach heights or jump down slopes for more momentum. His Shield Ability is a HoverJump that acts like a tiny double jump to remain on the air.
