Inspector 13 (Jess0312 version)

Inspector 13 (Jess0312 version) is the forty-fourth episode of Ben 10: Ultimate Alien and the twelfth episode in the third season. This will be based on the real episode Inspector 13, except it will feature Shiori and Shiki Sakurai again and this time, Izumi Kurokawa.

Plot
A Techadon master visits Kevin's garage, looking for an Omnitrix signal. Kevin attacks, ending up unconscious. Gwen later finds him clad in sports clothes as they promised Julie they'd help her practice, Kevin points out the need to hunt down the weapons master as he is a bigger threat than every Techadon they've ever faced combined.

Meanwhile, Ben and Julie are playing tennis while Shiori and Shiki, Ben isn't doing well, but then he transforms into Echo Echo to play better against Julie. Inspector 13 arrives on scene, he wants to study the Ultimatrix so he captures Ben. He takes Ben on his ship, telling him that he was sent to investigate a series of Techadon unit failures and wishes to reverse engineer the Ultimatrix to revolutionize Inspector 13's industry, so he tries to cut off the Ultimatrix, but Ben tells him that a security measure in the Ultimatrix will cause it to self destruct if he cuts it off, so Inspector 13 hacks the Ultimatrix instead, easily breaching the security measures and unlocks the Master Control.

Gwen and Kevin teleport aboard. Gwen destroys of the security machines the Inspector 13 sends at them, for they have no defense to Anodite powers, but they are adapting to her. Ben tries transforming, but it backfires, causing Gwen and Kevin to transform into Diamondhead and Jetray respectively. They are released off of the ship, falling down to Earth. Gwen (as Diamondhead) encases herself and Jetray in a mana crystal by accident, allowing them to land safely.

Inspector 13's ship is damaged in the battle, so he flies to the Techadon Factory in downtown Bellwood to use its technology and materials for repairs. Ben is able to escape into the factory, and the Weapon Master pursues him.

Ben uses some Techadon hands from the incomplete Techadons to try and defeat Inspector 13. In the battle, Gwen, Kevin, Shiori and Shiki called Ben that they want into normal, so Ben changed them. Gwen, Kevin, Shiori, Shiki and Julie drive to the Techadon Factory, Gwen, Kevin, Shiori and Shiki are transformed into Clockwork, Wildmutt, NRG and Swampfire. Wildmutt is barely able to avoid traffic as he crashes just outside the Techadon Factory, which can't be moved. Clockwork remarks that the military has been trying to get into the factory for weeks, with no results. Ben tries to use the Ultimatrix as the Inspector 13 captures him. Clockwork is transformed into Humungousaur, Wildmutt into Way Big, NRG into Armodrillo and Swampfire into Water Hazard. Just before they both try to break in the factory, Ben presses the Ultimatrix, causing Humungousaur to turn into Upchuck, Way Big into Nanomech, Armodrillo into Ghostfreak and Water Hazard into Upgrade. Ghostfreak freaks out because she turned into a ghost, since she is afraid of ghosts, but is calmed down by Upgrade while Upchuck is disgusted by her powers with Nanomech trying to make her eat through the factory wall. She tries to, but the factory repairs itself and is impervious to Upchuck's energy balls. Izumi appears and was able to recognise Upchuck as Gwen, Nanomech as Kevin, Ghostfreak as Shiori and Upgrade as Shiki, because of their normal voices and agreed to help them to save Ben, despite thinking of him as a spoiled brat.

Nanomech flies through the hole Upchuck created before it regenerates after her attack. He attacks Inspector 13 as Upchuck, Upgrade, Ghostreak and Izumi arrives and eats the bonds holding Ben. She, Nanomech, Ghostfreak and Upgrade are transformed into Rath, AmpFibian, Fasttrack and Spidermonkey and start destroying the Techadons, as Ben uses voice command mode to make the Ultimatrix recognize him, turning Rath and AmpFibian back to normal. Ben turns into Four Arms, and punches Inspector 13, defeating him. Ben, Gwen, Kevin, Shiori, Shiki and Izumi force the ship to take off, and Ben, Gwen, Kevin, Shiori, Shiki, Julie and Izumi return to downtown Bellwood while Izumi, before leaving, kisses Shiki on the cheek, and Kevin teases him for that, much to the latter's chagrin.

Gwen tells Ben that since Shiori, Shiki, Kevin and she got Ben's powers, Ben might have gotten Gwen, Kevin, Shiori and Shiki's powers during that time. Ben feels frustrated that he fought the Techadon master with his human skills instead of seeing if he had Anodite, Osmosian and Shinobian powers.

Trivia

 * The aliens Gwen transformed into don't have a female appearance like in Gwen 10.
 * It is revealed that Echo Echo can also duplicate the things he is holding, however according to Derrick, this was a glitch power.
 * It is unknown why Ben did not simply transform when the master control was unlocked as seen in War of the Worlds: Part 1 when the master control is unlocked giving Ben access to transform through voice commands.
 * The Weapon Master referred to the aliens by the names of their home planets (e.g.: Geochelone Aerio as "Aldabran" and Human as "Terran").
 * According to Geoffrey Thorne, Inspector 13's plasma cage and Gwen's powers scrambled the Ultimatrix into thinking Kevin and Gwen were both Ben and so the device transformed them both.
 * According to Geoffrey Thorne, Clockwork debuted in an "offscreen adventure" before this episode.
 * Inspector 13's plan is similar to Vilgax's in Secrets.
 * It is revealed that Shiki doesn't like bad smells, as demostred when he was Swampfire.
