Anton Arcane is an antagonist in the DC Universe, appearing primarily as the arch-enemy of Swamp Thing.
Anton Arcane is an old mad scientist obsessed with finding the power of immortality. He is able to mutate his henchmen into monsters known as the Un-Men in a manner similar to Frankenstein. He originally did this to his dead brother Gregori and made him Patchwork Man, his first Un-man. When the new plant hero Swamp Thing came he wanted nothing more than to capture him and to use his body for his research however he always fails. He is also the uncle of Abby Holland.
Besides being a genius he can also control the dead.
He also appears in the Swamp Thing the Animated Series. Like in the comics he and his Un-men constantly try different plots to capture Swamp Thing and use him. In this show he is voiced by Don Franks.
He later appears in the Swamp Thing movie and in the sequel The Return of Swamp Thing. In both movies he is played by Louis Jordan.
