Help changing nature!

[Hadditor]

Thanks to my n3DS being handily updated to 11.2 by my friend last month, my 3DS is running completely stock and I'm not able to do the stuff I want to, but that's another topic.

I ran into a shiny Mimikyu, and it has the worst possible nature you could have on a Mimikyu, which is nice. I was wondering whether anyone here would be able to switch it for me using PKHeX?

I am new to forums in general, so I am sorry if I have done something wrong, or if you are tired of these posts. I understand if you are haha.

Let me know, thank you!

Here is the bastard herself:
