All of these "who will win in a fight" hypotheticals usually try to measure characters on a physical strength aptitude. There's more to characters than their super powers. I'd like to see more fights based on diplomacy, ability to make the most friends, general kindness, etc rather than who can dominate the other. Among villains or villains versus good guys, maybe measure on persuasion.
There's a Nintendo website that allows you to sample Joy-Con colors here.
Well, I was fiddling around with it and noticed that what colors are displayed is determined in the URL, so I messed around a little bit and learned that you can use this to make colors appear that don't exist for that side (for example, making the right Joy-Con neon purple, when the color is actually exclusive to left cotrollers). This works with the wrist straps, too. (This is an example of impossible colors.)
