One day, some wierd thing happened and Mario and Sonic fused together. They were cloned as one wierd thing. Sonic Xtreme attacked Sonic being faster than him. Then Mario tried to jump on him but Sonic Xtreme took a mushroom and grew all they way into space throwing Mario far back into the castle. He later attacked Tails. This got sonic really mad and Sonic still couldn't get him. He is very powerful and can destroy anyone. He is more powerful than Bowser and Eggman combined.
- He has a wierd crush on Cream.
- He is very good friends with Shadow.
