Eva-Lution:  Electrifying Rescue

It has been a day since Eva Eeveeson, an Eevee girl who cannot evolve due to having Everus, found a mysterious device that attached to her wrist, and using it, she transformed into a Vaporeon-themed heroine called Vaporista for a limited amount of time.  In the morning, Eva got up and removed her pink nightgown and put on a pink tanktop and white skirt.  She saw the device, which was still on her wrist, and saw the center was back on, showing the symbol that looked like a Vaporeon head.

"Well, I guess after I de-transform, it needs time to recharge," Eva said to herself as she went downstairs. Later, Eva went to her old clubhouse, which she still fits in, and sitting on the old bed cushion she uses as a couch, she looks at the device and finds out there are two other icons, an Espeon head and a Jolteon head.

"Looks like I can become an Espeon and a Jolteon as well.  I bet they would have different outfits and powers like Vaprorista," Eva said.  Suddenly, she heard a yelp for help as a couple of kids were in a burning house as firefighters (which are water-type Pokemon like Blastoise and  were at the scene.

"Those poor kids.  The firefighters won't make it in time.  Jolteons are known for lighting fast speed, so that is the best form for this emergency," Eva said as she hit the button, going through the transformation of losing her clothes, as electricity came out of the device and wrapped around her body, forming into a yellow long-sleeved leotard, in which the device became a belt wrapped around her waist as she underwent the transformation into a Joleteon.  When it was complete, a lightning bolt-shaped mask formed over her eyes, completing the transformation.

"Whoa, now this here is what I call a traditional speed-type heroine," Eva said as she looked at herself in a store window.  Noticing her voice is now a Southern Belle-type, she got an idea.

"Wow, I sound like a Southern lass in this form.  That's it, I'll call this form Electrilass," Eva said as she sped into the fiery building.  As she found the kids, a female Fennekin and a male Litten, she saw a robot near them.

"Whoa, so this the cause of this here housefire," Elecitrlass said.

"Help us.  This robot set Fanny's house aflame for no reason," the Litten, Larry, said.

"It thinks we have something it wants," the Fennekin, Fanny, said.

"I see.  Well, best to get you darlins' to safety first," Electrilass said as she picked them up and got the out, as the robot, who had a generic robot body, but the head that looks like a Magnemite, scanned her.

"Target recalibrated.  It seems someone else has the Evotrix," the robot said as it left the building.  Outside, the crowd cheered for Electrilass as the crowd went to her, only for the heroine to see her belt start blinking red.

"Sorry, folks, that's all the questions I can answer for now," Electrlass said as she sped away into an alleyway, just in time as she changed back into Eva.

"Well, that was close, but what was with that robot?  It didn't give chase," Eva said.  Later, on a spaceship, footage of Elecrilass's rescue is seen as an shadow-covered Pokemon looks on."

"So, someone has the Evotrix," the alien said as its eyes glew red.
