do you think Knux's real name is Knuckles?

[Jammin']

i think its Nick. Nickles. Knuckles. they sound similar.

 

[Basic Bronze Sonic]

Well it's Knuckles if we're talking main cannon... but if we're talking Archie Sonic, I believe it would be "Nucada <insert whatever the ancient Knuckles tribe name is here> echidna" because "Nucada" sounds like an ancient tribe name and it sounds similar to the word "Knuckles".
Well that's my opinion on what Knuckles's real name would be.

Spoiler: extra off-topic note

What if shadow the hedgehog's real name was "Dave Olberg Robotnic", yeah it would be funny if canonicly shadows first name was "Dave"
