Honestly, the absolute best thing to do in this scenario is to back up and charge a spark bolt. If you fully charged it, then the Arakune would either change his method, giving you an opportunity to jump over the cloud, or he would eat a spark bolt. If you didn't get to charge it fully, the Arakune probably would start to play more aggressively(Like trying to shark you) to prevent you from charging the spark bolt. If he kept homing in on you and didn't change his tactics, while you didn't charge your bolt, then are are a lot closer now to having a spark bolt, and will have to take the cloud like a man.
