One such adventure ends in a mishap involving one of Gwenís spells and the Omnitrix. The next night, Tetrax shows up at Benís house to tell him the Omnitrixís creator, Azmuth, wants to meet with Ben for some reason. The meeting doesnít happen though and when Ben is almost hit by an 18-wheeler and then attacked by a Toílustar, the race that Way Big belongs to, he and Tetrax have to work together to take out the giant alien. It isnít long though before the pair are attacked by a Galvanic Mechamorph (Upgradeís race) and Ben ends up fighting the technological alien all over the world as it keeps teleporting Ben and the new enemy to various places all over the globe.
To make matters worse, it seems something is wrong with the Omnitrix. Ben isnít turning back into a human, he just changes from alien to alien. The result is a pretty fun fight between the ever-changing mechamorph and many of Benís different forms.
Meanwhile, Gwen, Max and Tetrax gather at the site of the 18-wheeler accident in an attempt to track Ben, only to learn that Azmuth was on Earth and apparently the target of the rogue Toílustarís attack. When everyone finally gets together, Benís malfunctioning Omnitrix actually sucks up Ben, Gwen, Tetrax and the enemy Mechamorph and they all find themselves in a computer-simulated world used to simulate the different home worlds of the various aliens stored in the Omnitrix.
Ben 10: Destroy All Aliens has several special features, but none are very long. One is a behind-the-scenes segment that was apparently aired on Cartoon Network as a sneak peek of the movie before it was shown back in March. Another goes into detail about the different stages that a single scene in a CG series goes through before it looks like its final form. There is also an art gallery and several deleted scenes. The final featurette talks about the work that went into designing the CG characters so that they keep the feel of the original show.
Ben 10: Destroy All Aliens is a fun film that complements the rest of the Ben 10 series nicely. There are some pretty interesting fights and the story as a whole feels like a long episode from the original series. Any fan of the other Ben 10 offerings should enjoy this DVD as well.
