It just... it's blamed for all of the disasters it tries to warn people about, but it still shows up on the off chance it can warn someone in the area. It's driven to near extinction by these actions. You literally can find them in areas that are going to have something horrible happen in the plot eventually, so it isn't just the pokedex making shit up.

It just keeps risking its life to save people, time and time again at their own detriment. They've never completely lost faith in humanity. It's one of the few pokemon with a mega evolution pokedex entry that doesn't imply anything goes wrong with it. It just has wings that are for appearance, as the pokemon itself is incorruptible. It's SO FUCKING MAJESTIC! I just want to go up to one and hug it, telling them it'll be okay.
