Cartoon Network March 27, 2009 Ben 10 Alien Force S2 Ep 12 War Of The Worlds, Part 1 & 2

War Of The Worlds Part 1
Paradox and Azmuth arrive on Earth to warn Ben of the approaching Highbreed fleet. Gwen and Kevin gather all the allies they've met to counter the threat. Meanwhile, Azmuth reveals to Ben that the Omnitrix contains the DNA of every sentient species in the galaxy, 1,000,910 in total, and unlocks the Master Control so Ben can effectively combat the Highbreed.

War Of The Worlds Part 2
The team has to get to the captain of the fleet, on the Highbreed head ship to stop the invasion. Ben, Gwen and Kevin quickly head to the captain of the fleet. The Highbreed commander and the team fight. The trio is then surrounded by a group of DNAliens, but are saved by Grandpa Max, Pierce, Helen, Manny, and one Null Guardian, who have regained control over the Null Void. Ben, Gwen, Kevin, Azmuth, and Ship as a spaceship head to the Augstaka, which is the homeworld of the Highbreed to confront the Highbreed Supreme after the commander tells them that he is the only one who can call off the war. When they get to Augstaka, they are captured. Ben escapes his confinement by transforming into Humungousaur. The team breaks out and confronts the Highbreed Supreme in person. Ben uses the Omnitrix to detect genetic damage in all the Highbreed. It sends out a pulse which attaches Omnitrix alien DNA to every Highbreed. The Highbreed Supreme is disgusted by Ben's action, and considers mass suicide as the species' only dignified exit. Before he can follow through, Reinrassig III comes in and tells the Highbreed Supreme that this genetic recombination has allowed their species to survive. Reinrassig, whose Methanosian DNA has grown further up his right arm, is otherwise unaffected by the genetic recombination. Seeing Reinrassic's firsthand knowledge of introducing additional DNA, the Highbreed Supreme steps down and names Reinrassig the new Highbreed Supreme. With this, Ben asks Reinrassig to call off the war, which he does. The two shake hands before they depart. Back on Earth, Gwen tells everyone that Darkstar escaped, to which Ben replies that they will find him later. Ben discovers that the Master Control got shut off. When he asks Azmuth how to turn it back on, Azmuth smiles and tells him to have fun figuring it out. He teleports away, leaving Ben free to try out a new alien that just emerged.
