Sonic is like Goku in the fact that they are both fast, goofy at times, heroic, turn super, and like to fight. They also have several other transformations.

Super Sonic is like Super Saiyan Goku for reasons already discussed.

WereHog is like Great Ape Goku because they turn into large, rampaging beasts at night time (in Goku's case, only during the full moon)

Then comes Hyper Sonic and anything after Super Saiyan, quite possibly just Super Saiyan 2. Both have an electric yellow aura, glow more brightly than their original forms, and are much more powerful than their first forms.

Amy and Chi-Chi (Goku's wife) are similar because of their relationships to the hero. Amy is always chasing Sonic and has a large crush on him. Chi-Chi did the same with Goku in their early years.

Vegeta and Shadow are also incredibly similar. Both have extreme rivalries with Goku and Sonic, and they are powerful people that everyone loves. They are also heroes or villains depending on the situation.

This one is a bit harder to see, but there is a slight similarity between Bulma and Rouge. Both are technological geniuses, the core of perverted jokes, and love the anti-hero. Vegeta shows no love for Bulma but she definitely loves him a lot. Rouge has shown feelings for Shadow even though he doesn't think of as her any more than just a friend.

Krillin and Tails have a large similarity. They are incredibly smart, kind of weak, and the best friends of the hero. They also have known the main character for a very long time and have stuck with their best friend through thick and thin.

This one is very hard to see, but Metal Sonic and Cell have similarities. Metal Sonic is a robotic counterpart of Sonic, and is very powerful. Cell has the DNA of Goku, as well as many other people. He is also very powerful. It would definitely be a good fight to see.

I don't see Dr. Eggman as Frieza, but as Dr. Gero instead. They are evil geniuses who create robots to serve their vendettas against the main character. They've also had creations that betrayed them.

16 and Gamma are incredibly similar. Both are powerful yet they try not to fight unless they have to. They are minions of their creators, but sadly, end up dying in sad, sad ways.

Piccolo and Knuckles have a large similarity. Both are rivals of the main character who started out as their enemies but then became their good friends. They are also very powerful. However, Piccolo is very intelligent while Knuckles is stupid. That's my only difference between them.

I'm not explaining Future Trunks and Silver. Look that one up yourselves.

Well, that's what I've got for right now.
