Vilgax's ship was being repaired by drones.
Vilgax spoke to Robot Lieutenant. "What do you mean it's not there? This battle nearly costs me my life, and you say the Omnitrix is no longer aboard the transport?!"
"Sensors indicate a probe was jettisoned from the ship just before boarding. It landed on the planet below." Robot Lieutenant said.
Vilgax spoke to another nearby robot. "Go. Bring it to me."

"So what do you think we should do?" Heatblast said. "And the girl; who do you think she was? She was...cool."
Kuri rolled her eyes. "That's such a boy thing to say. She saved your bacon."
"She called herself Miko?" Max asked. "And the watch won't come off?"
Kuri pulled on it. "Nope."
Max looked from Kuri to Ben. "No more fooling around, both of you. This is dangerous."
"Both?!" Kuri complained.
Heatblast turned back into Ben. "Whoa finally."
"Good, you're back to normal. Now both of you behave, I'm going to the crash site." Max said.
Xxx
Ben played with the Omnitrix.
"You'll get in trouble." Kuri said. "I'm going to take a nap."
"What? You aren't even curious?" Ben said.
"Watch out for robots." Kuri said and went inside.
There it was again. Her eyes went from blue to silver! Ben wondered what it meant, but he didn't have time for that now. He was alone at last, and he was going to try out the Omnitrix!
Ben activated the Omnitrix and transformed to Wildmutt.
Wildmutt fumbled around for a while before figuring out that he saw by smell, then changed back.
Around that time, the drones arrived.
Ben destroyed the first drone.
"Yes!" Ben said. A second drone arrived. "Whoa. Not good."
Miko landed in front of Ben. She put a hand on her pendant, but it burned her, leaving an angry red welt on her hand.
The drone fired at Ben, and Miko cried out. "Ben! No!" Miko threw out her hand and a silver light hit the drone and saved him.
"Ugh! How'd I do that? Well, here goes! Back up Mr Roboto!" Miko hit the drone several more times with the silver light.
"Never thought I'd say this, but am I glad to see you." Ben said. "You have more powers?"
But Miko was gone.
A sleepy looking Kuri came out of the Rust Bucket just as Grandpa Max entered the clearing.

"I was worried that you might get popular with that thing on your wrist. That's why I asked you not to fool around with it until we know what the heck it is." Max said.
"Sorry, Grandpa. But at least I figured out how to make it work. All you do is press this button. Then, when the ring pops up, just twist it until you see the guy you wanna be. Slam it down, and bammo! You're one of ten super-cool alien dudes!" Ben said.
"How do you stay an alien and not transform back?" Kuri said.
"I kinda haven't figured that part out yet." Ben said.
"With a device as powerful as that watch clamped on you, my guess is we better help you learn… fast." Max said.
"Alright!" Ben said.
The Ranger spoke on the radio "Mayday! Mayday! Somebody help us! We're under attack by some sort of - I know you're not going to believe me, but - …robot!"
"Sounds just like those things that attacked me. Must be looking for the watch. Those people are in trouble because of me! I think I can help them." Ben said.
"You mean we." Kuri followed after him.
Ben, Kuri, and Max went into the woods for Ben's transformation.
Ben activated the Omnitrix. "Yeah." He started turning the Omnitrix. "Eenie, meany, miney..." He choose Diamondhead. "Here goes."
Ben pressed in the Omnitrix and turned into Diamondhead.
"So what can this guy do?" Kuri said.
"I don't know, but I bet it's gonna be cool." Diamondhead said.
The giant robot attacked people.
Miko landed in the midst of them. She fired several flares of silver light at the robot.
"Looks like papa robot this time." Diamondhead turned to Grandpa Max. "I'll get gear-head's attention, you get the campers to safety."
The giant robot grabbed the park ranger.
"Leave him alone! You want someone to pick on, try me." Diamondhead was flown away by the giant robot and crashed with a nearby truck; got out from the pile by his sharpened arm and examined it "Cool." Diamondhead attacked the robot but ended up being trapped under its legs. "Uh-oh, think I'm in trouble."
Max saved the Ranger.
"What is going on here?" Ranger said.
"You probably wouldn't believe me if I told you. Now come on." Max said. "Where's Kuri?"
The ranger hesitated, but ran once the giant robot threw Diamondhead into his truck.
Diamondhead saved Miko from the tree.
"So, we even?" Diamondhead said. "Kuri."
Miko looked up at him in shock. "How did you..."
"Both Kuri's and Miko's hand is burnt from the necklace. Not to mention the whole disappearing and reappearing thing. You really weren't gonna tell me?" Diamondhead looked really hurt.
Miko sighed. "I'm so sorry. Grams told me I should never tell anyone. It's part of the Wiccan Rede...but, uh, later!"
The robot grabbed Diamondhead. "Uh-oh!" Diamondhead struggled and broke one of robot's arms.
Diamondhead got shot and was flown towards a storage.
"Ben!" Max said.
Diamondhead taunted the giant robot. "C'mon. Burn one in here."
"Get out of there. Run!" Max said.
Diamondhead reflected the blast as the giant robot blasted at Diamondhead. "What comes around goes around. Let's see how you like it, ya techno-freak!"
Diamondhead cut the giant robot in half with the reflected blast.
Miko hit the robot with a silver blast, destroying it."Alright!" Max said.
"Oh yeah! Who's bad?!" Diamondhead jumped up and down. "Yeah!" Kuri (already back to normal) and Max waved at him to make him notice and shook their heads in embarrassment "Well, I…think my work here is done." He ran away.
"Who was that guy?" Camper said.
People looked around and just shrugged.

Vilgax knew the failure to retrieve the Omnitrix
"Failure?! Unbelievable! The puny Earth being that is keeping the Omnitrix from me will soon hang on my trophy wall!" Vilgax said.

"So explain." Ben said.
"Relax." Kuri said, holding her mask. "I was raised in Japan. In Japan there is a kekkai, a barrier. It bridges this world and a world filled with monsters called Yokai. Because the kekkai is there, many monsters come through and cause carnage. I became Miko because I had to."
"But where'd you get your cool powers?" Ben asked.
"A miko is a priestess Ben." Grandpa Max said. "Her Grams was a miko before her. But her mother didn't have powers."
Kuri laughed. "Mom had powers, she just chose to destroy them on her own. She wanted to be human. But she promised me to Grams, and every summer until I turn eighteen, I train on the Isle of Skye."
"We're just lucky to have you this summer." Ben said.
Kuri winked at him. "Thanks Ben. Now, don't you have something to do before summer can really get going?"
Her eyes flashed again.
"Oh? Yeah!" Ben turned into XLR8 and ran off.
"Ben!" Grandpa Max said.
In a few minutes, XLR8 arrived back at the RV.
"Ben?" Max said.
"Yup. Hey, check this out!" XLR8 used super-speed to break camp and packed the baggage in record time. "Pretty fast, huh?" The Omnitrix timed out; XLR8 turned back to Ben.
"I think this is gonna be the best summer ever." Ben said.
"Absolutely." Max said.
"It's definitely going to be interesting. So, where'd you go anyway?" Kuri said.
"Just had to take care of a couple of things before our vacation really got rolling." Ben said.
Cash and J.T were hung on a tree by their underwear.
"Dude, how'd we get up here?" Cash said.
"Uh, I'm not sure. It all happened so fast." J.T said.
"Hey, somebody? Anybody? Little help up here, please." Cash said.
