Agent Six and Bobo Haha had encountered a pack of Scorthius in a desert. They were attacking them because Bobo had intruded into their territory. The number of Scorthius' increased when Bobo shot at their nest. Later, when they were surrounded, the Scorthius were killed by falling ice cream trucks that were sent coincidentally by Breach using her portals.
When Van Kleiss was trapped inside a sandstorm with Rex, he snatched a passing scorpion and activated its nanites, thus turning it into an EVO. Instead of attacking Rex, the EVO turned against Van Kleiss. It was soon cured by Rex when it ran after him next.
