I think this has potential, it could make for a very unique battle theme with some touches. The opening run starts off quite fast but after a second slows down to a more digestible pace. I think you should use that latter pace for the intro and outro. Maybe you could also use that synth from the intro as a bass for the middle section to support the spooky pads you have. It could establish a more defined beat, the pads make the downbeats a little obscure, which wouldn't be a problem with a bass driving the music. Drums here would also be a nice addition. But I think it's cool to have a battle theme based off a specific Pokémon type, keep writing!
