had an idea for underswap sans where he does still mostly act like canon sans but kinda ends up looking like fanon swap sans by coincidence

he joins the royal guard to protect papyrus, wears a simple shirt because it’s convenient to put on easily, the blue scarf because he gets cold, and the gloves because he works with explosives and doesn’t wanna get gunpowder on his hands

And then i had a different idea where snowdin is replaced by a hot tropical area so that renders the scarf thing null
