Victor Emilio Validus is the father of Elena Validus and appears in the movie Ben 10: Alien Swarm. He is a human and a Plumber. He is the former pupil of Max, who planned on passing command of the Plumbers of earth to validus and retire. However, Validus was discovered stealing alien technology (a serious violation of Plumber regulations). Feeling deeply betrayed by Validus, Max did not believe him when he explained that the alien technology he stole was in reality an alien species known as the Hive. Validus was expelled from the Plumbers in shame. Later, Max would discover this was a mistake.
Ben 10 Alien Swarm
Prior to the movie, Validus was studying the chips to find a weakness. During his studies he became host to the Queen of the hive. Using his Plumber knowledge, the queen upgraded the chips and later used his body to mass produce them. When the team arrived to destroy the queen, they discovered that he was host to her. While Gwen and Kevin insisted on killing Validus and the queen with him, Ben decided to use his latest transformation, Nanomech, to go into Validus's body and fight the queen head on.
With The Queen gone, Validus reunites with his daughter and Max apologizes for not believing him. Validus admits he was wrong to have tried to do it alone, and realizes he should have gone to Max for help in the first place.
Ben 10: Ultimate Alien
Victor reappears in Revenge of the Swarm. He was presumed dead, which ended up being true when Gwen sensed him underground in the cemetery. His daughter, Elena, found some of the Nanochips and studied them. It turned out that she was being controlled by them and could make them shapeshift into anything. The chips rendered into the form of Victor and attacked Gwen and Kevin.
