El Mal Verde is a giant green monster with an iron mace-like right arm, brown mustache, a black sombrero.
El Mal Verde is the largest and most dangerous supervillain of Miracle City. Every superhero (except White Panthera) has been devoured by him. White Panthera fled from battle from him so his family would not he alone. Years later, El Tigre thinks his father ran away from a fight with Mal Verde. So El Tigre had to face Mal Verde alone to preserve the Rivera family name, but he is no match for him. White Panthera managed to help El Tigre defeat Mal Verde. In the special episode, " The Good, The Bad and El Tigre", El Mal Verde is easily defeated this time due to a cavity in his front tooth. In the Series Final, he gets burned by the volcanic fire.
