if, lets say, karkat and nepeta were to have a fight, through scientific and canon evidence, also your own opinion, who would win? (its okay if you have no idea or don't wanna take the time to find out, im just a bit curious.)

Nepeta would win, Karkat is a crybaby and Nepeta is a badass huntress. Plus using a sickle leaves openings that Nepeta could take advantage of using her better speed and cat-like reflexes.
