Comic Series Edit
In the Comic Book Series, First seen in issue 24, Hectro is 783 human years old. This Tamer was imprisoned for life for his crimes against monsters. Hectro was labeled as the freak in his childhood because he was born with two left hands but was not left-handed. He is sinister by nature, turning his passion for the circus into a nightmare. Sinistro represents one of the darkest moments of the history of Tamers. He was captured by Ezeria Zick but later escaped through cracks in his Dom Box, which, because of his passion for the circus, was in a pattern of a carnival. After his escape, he kidnapped Bombo and the other monsters to show in his horrible circus. Bombo alone, because of his stomach, was forced to give up his invisibility and fight in a wrestling ring as the Great Chumbo, swallowing his opponents and spitting them out. This was a great hit for Hectro as Bombo made him a lot of money. Zick and Elena came to rescue Bombo, breaking the other monsters out of prison. They tried to stop Hectro but he had escaped. Hectro was seen again in the 29th issue where he forced Zick to give up his Dom in order to save Elena, but Dom energy that was kept in the Dom box was too much to contain and exploded, killing him along with other Dark Tamers.
