If you'd like to plan out anything with my characters please either post in this thread or direct message me on #slack
Due to having multiple accounts it's simply easier for me to keep messages in one place rather than rely on the inboxes of each character's account. There's also no official/right way to set up planning threads, I just decided to as I play more than one character and am thus on more than one account. That being said if anyone likes this idea/format they're welcome to use it themselves!
Below are general or specific ideas I have in mind, but feel free to contact me even if you have an idea not listed below! It's totally fine and you can probably think of something more interesting than I can, anyway.
Alphys The Pokemon fossil scientist and reclusive nerd of the desert
Pretty reclusive, so you'll probably have to come to her unfortunately! The two main reasons would be having a fossil that needs reviving or having Pokemon that need healing.
Please make sure you actually have a fossil in your inventory! (Or don't and bring her a fake/mistaken fossil. Or show up demanding she give you a fossil. Or just show up, anything works!)
If your Pokemon need healing you're welcome to drop in and bring them to her. The machine takes a little while to heal everyone, so you'll have plenty of time to strike up a conversation. (Or stand around awkwardly, start a fight, geek out with her, etc etc)
Or maybe you didn't even know her lab was for and just decided to investigate and find out.
Kyles Pokemon contest host and star of wherever he happens to be Mettaton
Mettaton is far easier to work out a thread with. He's all over the place in Kyles City (and even nearby areas sometimes!) and unafraid to insert himself into a situation. And with a Magneton who knows teleport he can easily show up to most other towns and cities due to having traveled across the Konah region. As long as your character is interesting enough to get his attention he'll interact with you. And if your character isn't interesting enough then have fun making a scene and getting his attention.
Seriously though, between Pokemon contests and practically any sort of television show you can imagine there are plenty of ways to interact with him. I'm open to practically anything!
