Don't just barge into someones fight project and one shot all their OC's. It's their project and you need to obey the rules in place. If you want to remix the fight project to fight another oc, you'll need to PROPERLY read the rules over, and stick to them throughout the fight. If you continue to disobey the rules, you will be one shot every time, or have your sprite deleted every time.
Why does this glitch and lag. Im gonna use the death screen more often.
