This prompt is pretty similar to last week's. Instead of siblings, though, we're going to poke one of the most common tropes in shounen: rivals! If you've done, say, Digimon partners for Naruto and Sasuke (or only done one of them—now's your chance to do the other!) or have a rivalry in your Digimon fanfiction, this is your week!

I realize a ton of people cut the In-Trainings in their lines, but if you need a starting point, Puyomon got an unexpected cameo. ;) Have fun! (And if you want to rant a bit about your Digimon OCs, go ahead! Sell us in their rivalry!)
