Awesome!!! Resemblance to Cell and Mecha Sonic.
Mecha Sonic, kinda reminds me of Cell in DBZ, because, he was, well, let's just say that the emeralds are like the androids and he was looking for those emeralds to become complete and Cell is looking for those androids to become perfect and Mecha sonic probably needs 4 emeralds to become imperfect, and 7 to become Perfect Mecha Sonic. Just like Cell needs 1 android to become imperfect and 2 to become perfect. They also resemble because, both Cell and Mecha sonic can use Kamehameha. It's complex but, if you can work out what I'm saying, it'd be simple. You'd probably have to watch DBZ in order to understand me completely.
