How many Pokemon attacks exist outside the games? Well, we got a video for that.
We have a video by TheAuraGuardian who has looked across several pieces of Pokemon media to see which attacks exclusively exist in that media. There are plenty of moves that exist in on the anime. Some of them are good. Some of them are pretty bad. There are also some egg-cellent attacks from the TCG.
Give this video a watch and see if there are some attacks that you like and wish were in the main series Pokemon games.
