The Swap Cop Sans probably has a more positive and straightforward personality. He believes in the good of the system and is dedicated to it. However, Criminal Underfell Sans is more complex. He may seem tough and cold on the outside, but deep down, he could have his reasons for being a criminal. Maybe he's been wronged in the past and is now acting out. So, while Swap Cop Sans is more black - and - white in his thinking, Criminal Underfell Sans exists in the gray areas.
Often, there's a plot twist where the Criminal Underfell Sans reveals a hidden side of himself that is not entirely bad. He might have been forced into a life of crime due to certain circumstances.

At first, Sans would probably be a bit shocked, but then he'd turn on his laid - back, sarcastic attitude. He might make jokes at Gaster's expense, which could either annoy Gaster or make him respect Sans more. If Gaster tries to harm him, Sans could use his shortcuts to dodge attacks and try to find a way to reverse the situation. He'd also likely be thinking about how this affects his friends in the Underground, especially Papyrus, and try to find a way back to them.
