Recently, several authors have studied the possibility of overspinning orovercharging an existing black hole to destroy its event horizon and make thecentral singularity naked. When all the effects are properly taken intoaccount, any attempt to destroy the black hole seems to be doomed to fail, inagreement with the weak cosmic censorship conjecture. In this letter, we studythe possibility of destroying the event horizon of regular black holes. Theseobjects have no central singularity and therefore they are not protected by thecosmic censorship hypothesis. Our results strongly support the conclusion thatregular black holes can be destroyed. If we believe that the centralsingularity in astrophysical black holes is solved by quantum gravity effects,we might have a chance to see the black hole's internal region and observequantum gravity phenomena. As our finding implies the violation of the blackhole's area theorem, the collision of two black holes may release an amount ofenergy exceeding the Hawking bound, which can be experimentally tested bygravitational wave detectors.
