If you add someone new you gotta put a little card about them in the project they're added, just like the ones for the other fighters. I can't evaluate their power level and stuff if you don't
Wait do any of your fighters have any way of taking out Sekhmet? Because if not then that's gonna be a problem, and I'm probably just gonna make something fall out of the sky TBH Still gonna need to use it wisely, but it will let you actually be able to defeat her
