-- Sev Tcheru src

Sev Tcheru is a being living in Earth's Gobi Rainforest. Brainiac 5 had worked with him when he tried to find a way for Supergirl to return to the 21st century, by furter developing Brainiac 5's Chronexus (a time window). The Legionnaires Lightning Lad, Supergirl and Saturn Girl encountered him when three of them were on a search mission to find their missing member, Cosmic Boy. Brainiac 5 and Sev had originally planned to trick the Legionnaires into that he were going to conquer time (beginning with the 21st century, with some sort of chronobomb, which Supergirl would naturally try to prevent). To combat them, Sev changed himself from his superevolved state into a more primitive one, a form strong enough to hit both Supergirl and Lightning Lad. After a brief battle that crushed the roof, Supergirl saw Sev's updated Chronexus, showing Earth of the 21st century. When she used her telescopic vision through the picture, she saw Black Adam battling the Marvel Family (during the World War III event). When asked what this meant, Sev told them about his work with Brainiac 5, and the Legionnaires present convinced Supergirl to return to her native era. Before telling the Legionnaires that Supergirl arrived safely and survived World War III, he had to erase Supergirl's knowledge of the Legion, as knowledge of future history is dangerous.[1]


  • Controlled Evolution: Sev has the ability to shift himself between evolutionary states. Usually, he takes the form of a human one billion (and one thousand, counting from the 21st century) years in the future, but have also shown a form looking like a Neanderthal.
  • Evolvo Lad is also sometimes known as Evolvo.
  • Sev possesses lots of various hi-tech constructions and devices, including an enhanced version of Brainiac 5's Chronexus, that is actually capable of making one jump in time, but not more.
