Trans-Dimensional Monster

The Trans-Dimensional Monster is a creature that appears in the episode Paradox. It appeared in Los Soledad and started to age everything it touches. It was born when Paradox's time-traveling experiment went haywire during the 1950's. In the end, it was revealed to be Hugo, Paradox's old partner. The creature is very dangerous, with enough power to desolate the entire land, and furthermore, Earth itself. When Ben's team traveled back in time and rescued Hugo the monster ceased to exist.
