Robo Sonic, or more commonly referred to as "Silver Sonic", is one of Eggman's robotic Sonic copies. In Sonic the Hedgehog 2, Robo Sonic or Mecha Sonic as he is known in the main games is the first line of defense aboard the Death Egg and is modeled after Sonic the Hedgehog and his abilities. The robot model is bulky but combat-capable with saw-blade quills, rocket boosters and a metallic spikeball-version of the Spin Attack.
In the Sonic Dimensions level pack, Robo Sonic is summoned by Eggman during the Death Egg Zone boss segment. He is invulnerable and will charge up his metalic spindash to charge at Sonic which can if aimed correctly can be used to attack Eggman.
