Boss battles in Super Brawl Showdown are a really fun idea. King Neptune and Santa Zim were neat surprises! However, I feel like some bosses don’t quite live up to their potential. For example, adding a Zombie Cosmo & Wanda was random, and they don't even attack, so maybe swapping them for Anti-Cosmo & Anti-Wanda could make more sense. Same with Dr. Plankenstein, which was just a Patrick + Plankton team-up. Also, I was surprised Avatar doesn’t have a boss yet — Fire Lord Ozai seems like a perfect fit. Just some ideas, but I really appreciate the creativity you’ve put into this already!
