This is Sans? and I thought that the is complete original but no someone stole it from Undertale Rusted and make it look like my very bad version of sans but much better

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.
