Sonic: The Final Showdown



After the battle of Sonic the Hedgehog and Dr Ivo Robotnik at the end of Sonic the Hedgehog, Dr Robotnik promised to remove all his badniks from Mobius. Robotnik was doing as he had promised, or so Sonic thought…

Dr Robotnik was secretly double-crossing Sonic. He was secretly torturing all of Sonic’s friends and was sending meteorites to the planet. Dr Robotnik then went to attempt to steal Master Emerald from Knuckles.

On Robotnik’s confrontation with Knuckles, they started to battle. Knuckles tried to fight Dr Robotnik but was sorely defeated and was left for dead as Dr Robotnik stole Master Emerald.

When Sonic found out about Dr Robotnik’s double-crossing, he severed his newfound friendship with Dr Robotnik and went to Master Emerald. He saw Knuckles dying and Knuckles’ last words were: “Sonic…Please get Master Emerald back and save all of mankind.”. Knuckles passed away. Sonic was furious and upset. After crying for a bit, Sonic stood up and lifted his fist in the air and shouted “I will kill Dr Robotnik:

In the Final Showdown.”

  • Ancient Ruin Zone: The new Labyrinth, with unfair jumps and a desperate rush to keep Sonic’s oxygen up.
  • Skylight Zone: Robotnik’s newly designed Star Light Zone. Careful though! Robotnik has pulled all the stops to make the level as difficult as possible.
  • Techra City Zone: Dr Robotnik’s final area, which is rumoured to hold Dr Robotnik’s world wide headquarters, but be careful! Dr Robotnik has protected his HQ by a huge refinery and a huge labyrinth.

As always, good luck and Have Fun!
