At Night Kim, Ron, and Team 10 were looking around a corner from a building to see an old ice factory in Los Angeles where the thief is hiding out.
"How did you know about the thief hideout Kevin?" said Kim
"He used to date her," said Ben who chuckles a bit
Kevin gives Ben a glare "we briefly dated and nothing else happen,"
"Okay then is there any traps or guards near the place," said Gwen
"No, she does not have any guard near this place but there a couple of traps in the front entrance we should take the back entrance where she got a key under a mat,"
"what if the key isn't under the mat anymore?" said Ron
"If not, it's not there, and then we'll just break our way in," Kevin cracks his knuckles.
The five teens go to the back of the ice factory to find the back door Kevins finds a key under a dusty doormat and opens the back door. The five sneak around the factory looking for the alien thief, and they find themselves in a large open room with a grey spaceship and the alien thief putting a bunch of boxes into the trunk of the ship.
"Looks like she planning on leaving earth," said Ben
"Good thing we arrive just in time," said Kim
"Boy for an old ice factory this place is still cold," said Ron and Rufus pops out of his pocket and try to warm himself
"Well she does have ice powers she probably uses this place to regenerate her powers," said Gwen
"Let's take her down before she gets the chance to get out of here with things she stolen," said Kevin
The five teens step out, and they go near the alien thief who sees them and stops putting boxes into the ship.
"Why are you humans doing in my hideout? You better leave now before you die in a frozen death?" said the alien thief.
"We're here to take back the royal sapphire that you stole," said Kim
"And put you back in the null void Liane," said Gwen
"Plumbers, of course, you guys would come to try to stop me from getting off this planet," LIane recognizes Kevin and smiles, "Kevin! boy, you have changed since our last time we went out on a date,"
"Things are different Liane you gotta pay for your crimes," said Kevin
"Please I remember all the times we broke into rich folks and rob them blind,"
"He is not like that anymore," said Gwen stepping in
"Yeah, I could see things are different now," Liane shot ice that traps Kevin whole body but his head "you've gotten soft,"
Ben quickly uses the Omnitrix to transform into one of his oldest aliens, "Heatblast!"
"A human transforming into a Pyronite I never saw that before no matter no one on this pitiful planet could stop me,"
Heatblast throws a couple of fireballs at Liane; she dodges them and shoots ice at Heatblast only for his skin to melt the ice into water. Gwen tries to trap Liane in with her powers by making several circles around her. Liane shoots an ice beam to blast herself away from Gwen circles, and she gets in front of Gwen and kicks her in the gut. Kim tries to hand to hand combat with Liane who got several hits on her.
"You fight well for a human," said Liane blocking one of Kim punches
"Thanks, I fought someone like you, but she makes plasma with her hands," said Kim try to sweep the legs of Liane, but she jumps up, avoiding the sweep.
"Unfortunately, I'm more vicious," Liane tries to stab Kim with her hand, turning into an ice spear.
Kim dodges her ice spear, and Heatbleast throws an explosive flame that knocks Liane off her feet, and she starts to sweat. Ron kicks her in the leg out of frustration Liane froze Ron's leg to the ground and turns to three remaining heroes.
"Okay she is tough," said Kim
"Yes but looked at her she sweating after Ben explosive flame hit her," said Gwen
"I think I know what your thinking Gwen," said Heatblast
Heatblast gets Liane away from Ron with a couple of fireballs and then makes a ring of fire around her.
"You think this is going to defeat me, a pathetic ring of fire," said Liane Kim, and Gwen jumps into the ring of fire.
"No both of us will," said Kim
Liane tries to escape the fire, but Heatblast blocks her way, Gwen pulls Liane toward Kim who punches her in the jaw and kicks her in the side. Liane tries to use her ice powers, but she cannot even form a block of solid ice due to heat coming from Heatblast's ring of fire. Gwen teleports behind Liane and kicks her in the back, going toward Kim, who gives the final blow with one punch to the face.
"We did it," said Kim
The ring of fear dies down Gwen makes a handcuff around Liane's hands and cuffs her.
"I'll call Plumber HQ that we got one of the wanted alien criminals," said Gwen
"Ahem, what about us," said Kevin referring to him and Ron are still stuck in ice
"Don't worry guys I got you," said Heatblasts coming toward them with his fiery hands making Ron gulped in fear
Somewhere in a dive bar in Las Vegas, a man wearing all black suits and red-tinted circle sunglasses sitting at a barstool drinking a bottle of whiskey and a pretty blonde woman in a tight red dress comes up to him.
"So mister, what are you here for in Vegas?" said the blonde woman sitting next to the man
"I'm just passing through," said the man
"So, where are you going?"
"Middleton California,"
"Middleton, I've been there a couple of times, why are you going there?"
The man drinks his glass of whiskey "To finish what I started a long time ago,"
