This is the one that people say it's perfect for error sans https://www.youtube.com/watch?v=wxy2z5ZgD9w

Description: My name is "Sans" with "?" so my name is Sans?. I was made in the void, not by GASTER but by HZ. And unlike sans, I'm not making any joke except that I make them by accident. Heh... I have the determination that I can reset but I can't reset IF there's someone that has a stronger determination... yet when you try to attack me it will just like when you attack the amalgamate.
