The companies that made Pokemon, Kirby, Xenoblade, Earthbound, and Fire Emblem were made by studios founded outside of Nintendo, so they aren't Nintendo creations. Smash Bros isn't canon anyway.

Rosalina is not cosmic. Her base flew to the center of the universe in just a few seconds at a pace humans can detect. That means it was just very close. The very weak black hole that reset everything at an undefined scale was the result of the lumas interference, not Rosalinas power.

Shulk was granted a choice by someone else to recreate reality. It wasn't his power.

Most of these characters have never shown any destructive or durability feats to even a city level, or even neighborhood. I'm assuming thats also true of Naga even though i havent seen her feats, because people greatly exaggerate Nintendo owned characters just because of how popular they are. I'll have to post a screenshot of what I've said about Kirby on YouTube because it doesn't let me copy and paste everything from there on the phone. I don't feel like going on the computer just for that.
