I highly doupt he has determination. There just isn't any evidence. He doesn't melt or anything. The only reason he is hard to defeat is because of the Karmatic Retribution (or however its spelled). If he was fighting someone who is good, Sans would be having a bad time. Not to mention his ability to dodge. Determination doesn't give you the ability to dodge. That just makes zero sense. Yes, it's possible that Gaster gave Sans tha ability to use KR, but that doesn't mean it came from determination or anything.
