(This is all in author's note format)
Hello readers! It me the author. So if this got published in the middle of the story, that means I didn't get around to writing The next chapter on time. Shame on me. This is just how I write battle scenes, if you don't like my battle scenes don't do it this way.

First I have to decide which Pokemon are battling. I know kind of obvious. So for an example battle this chapter I'll use the man eating Bidoof and a Zangoose. Trainer A has Bidoof, and trainer b has Zangoose.

Second I decide what levels they are at. I like to keep them within a five level range of each other. So Bidoof is level ten for this example and Zangoose is also level ten.

Next I decide what moves each participant knows, I keep it within what they can learn at their level. A level 10 Bidoof can have Tackle, Growl, Defense curl, and an assortment of Tms. Zangoose will know Scratch, leer, quick attack, and furrycutter by the time it's level 10. Zangoose could also have a variety of Tms.

Then I do a very skeletal outline of the battle, which includes moves used, order of moves, and special effects. No orders or dialogue to complicate things.

Example

Bidoof used growl when released, as Zangoose charged with Furrycutter.Bidoof tackled Zangoose when Zangoose got close enough with furry cutter. Zangoose continued to use furry cutter again and again Bidoof could not tackle due to claws. Bidoof just used defense curl. Until Zangoose won.

After that I'll flesh it out a bit adding any dialogue to it. I wrote it from the Pokemon's point of view.

"Bidoof go use growl" Trainer A ordered. I did as he commanded, warning my opponents I was a force to be reckoned with.
"Zangoose use furry cutter. I want to get this over with." Trainer b ordered.
"Yes sir. I will obliterate this scum for you." the Zangoose loomed above me. He charged at me with his claws looking way to long.
"Bidoof use tackle." my trainer said as bored as ever. I wish he'd give me more credit. When Zangoose reached me I used the force of his change against him in tackle. He lashed at me with his claws I tried to dodge really I did. Blood dripped down my side. He came at me again bloodlust shining in his eyes. I curled up to protect my vitals. I felt lash and lash again as Zangoose tore my back to shreds. Finally I blacked out. Sorry trainer I failed you.

Lastly I separate it into reasonably sized paragraphs and check for grammar and spelling errors. Also I put in names here. Also check to make sure you aren't to repetitive.

Final copy

That's it. I really liked the last touch we're I had the main character lose, that's a nice way to spice up your writing. Mc can't win every. single. stinking. battle. It just gets boring after a while. See ya next time I forget to write a chapter on time. 👋👋. I am going on hiatus for a while as I write a few chapters ahead.
