Chinese name: Clown Fish mbth: Clown Fish Creator: Clown told the story of Clown Fish for the first time in Detective Comic #475 on February 1978. This kind of fish was originally just an ordinary fish in the waters near Gotham, but once a clown injected a special toxin into the water and created this creature. The toxin that makes clown fish is ineffective for people. Its original intention is not to poison others, but clown fish is ready to sell this special fish and get amazing patent fees. However, when the clown applied to the municipal officials for the patent of clown fish, the official in charge, G Carl Francis, refused him. The angry clown killed G Carl Francis and issued a notice that if the next person in charge could not apply for a patent, the final result would be death. Batman speculated that his successor was thomas jackson, so he and the gotham city Police Department tried their best to protect him. Thomas jackson mingled with the crowd in the middle of the night, but his cat ate poisonous fish and immediately scratched its owner. Thomas jackson is still dead. Batman finally found the clown and stopped his madness, and the clown never benefited from the clown fish. In the comic series Batman: Animation Series, the original comic story is basically restored.
