While Wald showed that extremal Kerr–Newman black holes in general relativity cannot be overcharged by test charged particles, this protection may fail in theories beyond general relativity. We have considered generic rotating black hole solutions beyond the Kerr-Newman family and examined particle absorption processes that could lead to overcharging and the emergence of naked singularities. Identifying regions of parameter space where WCC is violated allows us to place direct, physically motivated bounds on deviations from general relativity.en-USfalseArticlehttps://arxiv.org/pdf/2509.05087247000299 January 20260024021arArticleWOS:001671941200004
