Silver Sonic

The Silver Sonic (メカソニック) is the robotic version of Sonic the Hedgehog that appeared the Master System and Game Gear game Sonic the Hedgehog 2. It is the boss of the Scrambled Egg Zone.

History
In his 8-bit debut, the Silver Sonic is Dr. Robotnik's super-secret weapon which resembles the original hedgehog, although he is slightly taller and a bit low-tech. He has a metallic grey color scheme and possesses many of his organic template's own moves, including the ability to roll up into a ball and spin, though he has a few abilities of his own. Thankfully, Sonic is more nimble and can guard against most of its attacks. It is the boss of the Scrambled Egg Zone. If Sonic has five of the Chaos Emeralds upon defeating the Silver Sonic, it would also release the sixth and final Chaos Emerald, which would grant Sonic access to Crystal Egg; otherwise the game ends here.

Powers and Abilities
The Silver Sonic can roll and spin just like the real Sonic. If the Silver Sonic and Sonic spin attack each other simultaneously they will bounce off of each other, taking no damage. The rockets on his shoes allow him to dash, whilst the ones on his 'arms' propel him upwards. The Silver Sonic can also attack with a retractable claw, that seemingly comes out of his torso.

Trivia
