Although Blue and Red are still rivals, they still hate each other for some unknown reason, probably because Blue always has to clean up after Red's "shenanigans". Also, Blue just general doesn't like Red's personality, but yet, they're still in a like-hate friendship where they hate each other, but are willing to help each other. Also Blue is STRAIGHT which means he feels attraction to girls, not boys. Red is also a male btw, if you couldn't already tell. Overall, is actually a decent human.
