The main character, Omochao is a robotic Chao who used to help people. Now, however, Omochao has his own crazy adventures with his... erm.... friends.
Omochao's smart, funny, awesome sidekick, Tails helps Omochao with all of his adventures. He also likes to build things, such as planes and boats.
Omochao's ancestor likes to give hints on where the villains might be.
The most major villain, this person likes to pull strings from behind the scenes to make Omochao and Tails' life harder. But why? How? And what's up with the evil smell of death around places he's been, yet no bodies are found and nobody appears missing?
