How to make characters for a turn based battle system efficiently?

I am relatively new to unity and basically i want to make a simple Pokemon/d&d style battle as a sort of practice. What I really want to do is make it so for each possible character you can fight as/against I only need the smallest amount of code, like having a list of moves that i can just put onto specific characters, or having only one version of each character whether they are the player or the enemy. Most tutorials I've seen have separate code for enemies and players and that seems unnecessarily complicated. I'm just looking for general tips. thanks in advance
