This. It annoys me so much that I can't name something without a nickname at just because it was a traded Pokemon. Sure, Gamefreak, I'm sure when the trainer playing Emerald nicknamed their Registeel "REGISTEEL" it was out of pure, unending love. The kind of love that still lives on even after it has been traded. But to me, it's just a really annoying thing to have a Pokemon's name in all caps, especially when all other Pokemon in the game have normally written ones. What's even worse is when you can't rename or un-name your own Pokemon from other save files. It's such a slap in the face. "Oh hey, you want to give your Pokemon a nickname? Well too bad, it technically isn't yours because it's from another save file! Trololololololololololololol!!"
