The fast runs and dissonant chords sound like they could combine to create a nice ghastly battle theme,  but right now they are presented as two separate parts. If they overlapped and/or transitioned smoothly from one to the other, they could form a stronger whole.  A bassline or some percussion could also add a sense of movement which is good for a battle theme.

I like the runs but I feel like the bass parts under it are hard to hear because that’s what makes up a majority of the song, but whenever I turn it up to hear it I get jumpscared by the fast paced runs. Overall, it is very creepy and I like the idea.

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!

This honestly made me smile. Some Pokemon music is so crazy and chaotic and this definitely is giving that vibe. I think the beginning almost could be a separate track. I think the track would benefit from some percussion and a couple sections that are more melody focused to glue the parts together. Something to make it more structured of a composition. But altogether it's a cool really creepy. The beginning gave me Team Rocket Hideout from Pokemon Red vibes a little.

It sounds a little sparse now but I think it could be built up into something cool. The intro feels like it could lead into a fast battle theme. Something you could try is putting the spooky synth on one track and the fast arpeggios on another track at a lower volume and see if they fit together, and maybe put a fast drum track under it. Repeat the section a few times and there could even be a break in the song where it's just the creepy synth part by itself. Definitely keep at writing music because it seems like you have some interesting ideas, just maybe needing some structure.
