Backstory/Some other info:
In his universe, Sans was being used to test raw Determination on monsters. During these tests, he got exposed to Frisk levels of the stuff. This caused his to nearly turn to dust from straight-up Determination overload; as he was fading away however he had a split second to see and gain access to a save point. By loading that old save point, he was able to survive, but not without some serious damage to himself.
Negative Info about Deter:
The process of load a save that wasn’t his caused his to lose his memory and get thrown into an AU he did not know (although over time he does become aware of his origin). His health will slowly deplete over time until he has to load up another save. Although he is aware that he cannot truly die, Death is still a great fear to him, as his HP gets closer to zero, he comes distressed and paranoid, isolating himself until he loads a save. As well as allowing him to travel and stay alive, loading saves gives him a rush, similar to an addiction that he needs to have to stay alive.
Side Notes:
He has hoards of saves woven into his poncho (thus why it glows) that he can access to jump from AU to AU endlessly. He enjoys the company of other Sans he meets across the multiverse, was it allows him to feel parts of himself he cannot remember. He cannot use Gaster Blasters or Blue attacks because most of his magic goes into extending his HP as long as possible.
