How do you go about getting ideas for arcs? I’m struggling to figure out what I want to do with my character :(
Great question! This happens to be one of my absolute favorite parts of writing and pkmn irl itself. I've always been more of an ideas guy myself. I hope you don't mind but I decided to turn this into a bit of an overall tutorial for planning and writing arcs. Feel free to ask for any specifics because I could delve into my personal process for arc brainstorming, but I was admittedly writing this before getting ready for work and this post was getting kinda long haha
Knowing where to draw inspiration from can be a good place to start. It's wonderful to be inspired by music, a movie or tv show, a book, or even other people in the community and their writing. Ask yourself what elements of that thing draw you in. What do you like? What would you maybe do differently? I must mention though to be respectful of the work other blogs have put into their writing. Being inspired is a wonderful thing, lifting exact details or passages is not. If you're unsure, there's no harm is asking!
The most helpful thing I can tell you right off the bat is that you want to find out how to brainstorm. In schools they'll often try to teach you ways of brainstorming and outlining to structure your essay writing, if you're lucky they might even mention that there are multiple ways you can do this. The ones in school never worked for me personally, so for a long time I assumed brainstorming and outlining was a complete waste of my time and would launch straight into my writing drafts. But as I wanted to write more complex things and I wanted to indulge in more creative writing, I found myself getting stuck all the time. The truth is brainstorming is a helpful tool, but you have to know what type of brainstorming works best for you. Flowcharts, bullet points, stream of consciousness, word clouds, moodboards, drawings, whatever it is that gets your creative juices flowing. In my experience it works best to remember that not every one of these elements will make it into the final arc. You want to get your ideas down first and trim the excess later. I personally pay for a program (Milanote) that allows me to brainstorm in the methods that work best for me, but by no means do you have to pay for a program to do this. Pen and paper works just fine.
The next thing you wanna do is establish what you want your arc to do. Not every arc has to be a grand character development, but all arcs do something. No matter how small that something may be, something has to change as a result. Maybe your character meets a new person, obtains a new Pokemon, gets a new scar and a story to tell their friends, or maybe all they got was a t-shirt. If you already had a loose concept for your arc this can help you hone it. You can start asking yourself, "how does my character reach this point?" and work up to that. Map out what you think your character would do when dropped into a particular situation. This can also help you to establish the tone you want your arc to take. Is it silly and lighthearted or is it more serious and high stakes? Refer to the stakes tag post about proper tagging.
It can help to conceptualize your arc as a series of events rather than a single event. This allows you to understand how many posts you may need to split the arc up into, how much time the arc may take, or other hard to sort details.
These things ramp up when you start to incorporate more people into your arcs. Planning with your fellow writers is extremely important and that requires a lot of communication. Some writers prefer to do what we call pre-writing, which is typically you and the other writers get together and write out the posts in advance. This gives people the chance to look over each other's writing and make edits before the posts go live. Planning discords are useful for keeping things organized, but google docs or other collaborative writing programs can work just as well if those better suit your needs. Organize who is posting what and generally at what time, especially if the post involves other people's characters.
Remember all of this is for fun! These are not hard rules you need to follow. You should not force yourself to write things you do not like for the sake of others or for an imagined audience. Write what you want to write.
