So You Want To Do A Media Arc
Hello! Umbramatic here, with some advice on creating media arcs!
What is a media arc, you may ask? A miniarc or subplot that's based on media other than the Pokemon games. They have a long and storied history in WAAPT - mostly ones based on other video games, but movies and books and such have been used as well. As someone who's done two (Magic Mirror and Okamiquest) I felt I should help others by giving my advice. Here we go!
Step 1: Do your research!
You can't do a media arc without knowing the media in question, right? It's best if you experience the work you're adapting. Watch the movie, play the game, (Or watch a Let's Play) read the book. Even if you have before do it again so it's fresh in your mind. Take plenty of notes, maybe make an outline. It'll help!
Step 2: Adapt it!
You can't just drop a non-Pokemon story into the WAAPT world and have it work without a hitch. You've gotta Pokemon it up first! The simplest way to do this is replace many or all of the cast members and/or enemy monsters with Pokemon. However, you've also gotta integrate it into the WAAPT world without changing the WAAPT world's rules too much. For this reason, you might need to find a setting within WAAPT where your arc works best, and scale things down if necessary.
