I've a similar error for Bluestreak:
Spoiler, click to toggle visibiltyI removed that palette and he works fine.
Edit: IMO, Bluestreak's AI is alright at best.
He has almost zero defense and is only "formidable" from a distance where he can safely spam lightning.
Once in close, Bluestreak pretty much does nothing.
You should watch NxLbeta's Youtube videos to get a feel of how he plays effectively.
