The white hedgehog in question was "Nazo". You may be referring to this: https://www.youtube.com/watch?v=g-etGCr7SM4
and I assure you the animation and voice quality was nothing to sneeze at.

Found on Youtube a long time ago, probably around 2011-2013. It was a four-part animation about Sonic fighting a white hedgehog (whose name I believe was Nero? it was certainly not Silver), and having to continually power up in order to eventually beat him, which included eventually fusing with Shadow into "Shadic". The white hedgehog also kills Tails at one point I believe.
The animation and voice quality were both low, though I don't remember specifics about the style. I'd really like to find it again to see if it even exists anymore. Since I have such vivid memories of it, I can't imagine it being something I made up.
TYIA!
