Yes. He appears in the game: Sonic R. I have the game so I should know. Go to http://sonic.wikia.com/wiki/Metal_Knuckles if you don't believe me!
No sadly he is not, but in the future he may become a real character.
Knuckles is a video game character from the Sonic series, in which he made his first appearance in the game Sonic 3.Also in knuckles comics. He is a red echidna and sworn protector of the Master Emerald. He has powerful attacks and overwhelming strenght. The spikes on his fists really sting!He is not like other echida because his fists are real but other echida has metal knuckle.
Unless you count the various Shadow Androids created by Eggman to be Metal Shadow, no Metal Shadow is not a real character.
Sonic the Hedgehog is simply just a cartoon character that is made up for the purposes of entertainment. There are real hedgehogs, but none that can talk or run as fast as Sonic can.So hyper metal sonic isn't real then
knuckles XD
yes and no. he is his friend after knuckles discovered sonic trying to help him save the master emerald from robotniks evilness. but before knuckles knew this he was trying to stop him.
In terms of the Sonic the Hedgehog universe, yes. He makes an appearance in Sonic R, but that's all as far as I know. But, obviously, no Sonic the Hedgehog character actually exists. Hope I helped. ^^
