Scooby-Doo: Marks of Mysteries

This is an idea for a Scooby-Doo Anime.

Summary
After solving a mystery in Toyko, Japan, Mystery Incorporated is given an offer by a top secret agency who want their help in a special project. But after declining them, they soon find themselves being forced into captivity by these secret agents. Freddie and Daphne were the first ones to get captured while Velma warns Shaggy and Scooby of this matter. Learning that Scooby-Doo is a key element to their plan.

While she tries to hold them off, Shaggy and Scooby-Doo take the Mystery Machine and try to get away, only to be pursued by other agents of this secret, yet evil organization.

In an effort to save his friend, Shaggy tells Scooby to hide while he leads he agents somewhere else, having promise to come find him whenever he can.

After Scooby runs away to safety, he soon finds another teenage man like Shaggy, although a bit obesed. After being Scooby and renaming him to Scoobchi or something like that, he introduces Scooby to his high school friends (based on characters from High School of the Dead).

When they find out that Scooby-Doo is being pursued by these evil, secret, government agents, they wind up becoming a Mystery-Solving Gang themselves when creepy things happen in their home city.

Will Scooby-Doo and his new found friends solve all sorts of mysteries and solve the biggest mystery of all: How to save Mystery Inc. from this secret, evil government agency?
