The year was 2982, and the world was in desolation. Ever since the cartoon characters had come to life, they treated nothing good, especially the leader, Spongebob Squarepants. In 2145, a man accidentally plugged in his TV wrong, and ever since, the world was in ruin, the extinction of real life people coming in 2497. Unlike in cartoons, none of the characters were happy or funny, they were ruthless. All of them would kill off the humans, terrorizing them until they went into hiding, and even then, the cartoon characters hunted them down until they were considered extinct. This was carried out by the President Spongebob Squarepants, and his Vice President Homer Simpson. The only character with a little good in his heart was a hedgehog named Sonic, and this is who the story is about.

Sonic always felt different, if it was in the cartoon lobby where all the characters could relax, or while acting. Something just didn't feel right. and it all changed when he met a small band of video game characters that had escaped while the cartoon characters did. Sonic never told the cartoon characters about the video game characters, because they were different. The video game characters were kind, and didn't like the evil in the world. They were in hiding because they were afraid of the large army of cartoon characters. But that all changed when an entire group of video game characters showed up.

While Sonic was visiting the video game characters, a portal opened, and very strong looking men and women stepped out. They called themselves the Street Fighters, and their leader was named Ryu. They didn't know what had happened and explained that they were dueling, when all of a sudden, a bright light appeared, and then they were here. One of the original video game characters, Mario, explained the situation, and the Street Fighters agreed to join forces. Sonic kept all this a secret when he returned to the cartoon world, and never told anyone about them.

After a while, the video game characters devised a plan, and had Sonic find out what the cartoon characters defenses were, against newcomers. Sonic found out, and after telling them, they decided when to come out of hiding, and fight. When that time came, they were ready.
