Lek mating females away from the hotshot. A manipulative experiment using the little bustard, "Tetrax tetrax", was done to test the various lek evolution models. The experiment involved varying the size and sex ratio of leks using decoys. To test whether or not the presence of a hotshot determined lek formation, a hotshot little bustard decoy was placed within a lek. After the fake hotshot was added to the lek, both male and female visitation to the lek increased. The hotspot model considers the female density to be the catalyst for the clustering of males. This model predicts that leks will form
Ben 10: Secret of the Omnitrix signal, picks up Sixsix, one of Tetrax's rivals, and starts tracking Ben. While attempting to reach Azmuth, they are attacked by Vilgax. Ben is ultimately successful in repelling the attack, though Gluto is supposedly killed in the conflict while protecting Gwen, who blames Ben. Tetrax's ship crashes on Azmuth's homeworld.
