The New Archenemy: Pt. 1

The New Archenemy Pt. 1 is an episode of Ben 10: Unlocked where the first main protagonist of the series, Praxiss, introduces himself.

Plot
In a storage facility, an alien scientist named Dr. Kypler gets knocked out by an unknown alien, stealing something in the facility. The facility was intended by alien scientists to store various materials they needed for various experiments. When another fellow scientist, Dr. Ydison, goes to the facility, he saw the guards knocked out, and sees the alien stealing a slightly large container. But the action was fast, so he was unable to make out who stole it. Then he enters and finds Dr. Kypler unconscious.

In Arret, where Ben resided for a while with Natep and Orelis, Ben woke up seeing that the Ultimatrix was not on his arm. Ben is alarmed by this, and so Ben calls upon both of them to find out who did this. Both Natep and Orelis were surprised by this, as surely only Den and his friends knew they were here. Orelis checked for footage inside the home but there was no footage of someone stealing the Ultimatrix. Orelis had thought it wasn't Den or his friends for she said they weren't smart enough to operate the computer and remove the video. Natep had thought that it might be the work of Mafyozo, an alien mob boss who is on the run but was unsuccessful in being found by the Plumbers and other agencies. It turned out later though, that Orelis stole the Ultimatrix and used it for herself for a while. Natep got angry at her and placed it back at Ben's.

Meanwhile, another facility, this time of metalworks in Arret, had been attacked by multiple aliens. They stole a lot of materials. Ben had been notified by Natep of this, and fought against the aliens stealing them. Upon fighting, he retrieved back the stolen metal, but the aliens he fought had disappeared mysteriously.

Later, when Ben returns at his home, he finds Natep and Orelis gone. When he went outside, a group of aliens appeared, the one he had fought earlier, with extra aliens. Then Praxiss introduced himself in the hologram, saying that he has both of them and that if he doesn't cooperate with his plans he'll kill them.
