One theory is that the "animals" of Sonic's Universe tend to look similar. One can look towards the Echidna race. They have features similar to Knuckles the Echidna which can be seen in various flashbacks in Sonic Adventure. Also, Shadow cannot be a clone of Sonic because Shadow was unsealed by Dr. Eggman 50 years later after the Space Colony Ark incident. Shadow can also be seen as a different race of hedgehog due to him having more fur and his signature markings.
I'm srry, I think I know the simple, correct answer: He is a hedgehog, as is Sonic (I honestly dont know how the people in the TV series and the games could confuse them, they must be stupid).
Side Note: Oh and btw, Shadow IS NOT a clone of Sonic. He was created at least 35 years before Sonic was made (subtract the 15 years he is supposed to be old).
Shadow looks like Sonic expect hes black and red
Because they are hedgehogs.
Shadow is suppose to be stronger and faster But I like Sonic better.
Shadow doesn't like her but Amy likes shadow and sonic she has to deside so it's best to like sonic though cus shadow is just a recreation of sonic so i thank sonic and Amy are better together.
Because Shadow does not like Sonic.
shadow
you can texture hack sonic to make him look like shadow
Shadow looks like Sonic expect hes black and red

You can't, unless you use a hack that makes Sonic look like Shadow.
the black and blue are very closet with the whit (silver) and i think sonic and shadow and silver are brothers
the sega character "shadow" is not a playable character in ssbb however using a texture hack on sonic allows sonic to look like shadow. I would look on youtube to see this.
I only seen this by modding.
No, on youtube.com the users modified sonic's color making him look like shadow, they hack the game
to be honest i don't know but sonic does think of shadow of an ally shadow thinks of sonic as an ally even though they both still think of each other as rivals too they fight so much that it doesn't look like any of them are trying to be friends but they sometimes do it to prove something and/or just compete
Well They Both look the same but Sonic was a prince and Shadow was a creation of Dr.Eggman's.
Shadow sonic is like sonics shadow, since he can be the same as him for everything!
