"Ugh, we're finally out of that stupid forest!" Jessie says, with an obvious annoyed tone in her voice.
"Well we wouldn'ta been cooped up in those woods so long if James hadn't lost our map!" Meowth adds, glaring at James, causing Jessie to do the same.
"Oh give me a break already. Maybe I would have heard it fall if Jessie wasn't babbling about herself the entire time!" James refutes, ticking off Jessie even more.
"WHAT DID YOU SAY?" Jessie screams out, almost catching the attention of a nearby Officer Jenny. Noticing this the group hides in a nearby bush.
After waiting for about 5 minutes the group peaks out to see Officer Jenny is gone. Breathing a sigh of relief they emerge from the bush.
"Alright, we're here now so there is no point in arguing." Jessie states, still bitter about James' comments.
Looking around they can see their destination, Cerulean City. After many unsuccessful attempts at capturing Pikachu, they had landed in the woods nearby after having blasted off again. However after realizing where they were, the team quickly got a scheme brewing.
"Hey, ain't this the town that the red-headed twerp lives?" Meowth ponders aloud.
"Why yes, I believe it is." James answers.
"Aha!" Meowth continues "So yous thinkin' what I'm thinkin'?" Meowth says, as they all get mischievous grins on their faces.
The plan was simple. Team Rocket was going to bait Ash to coming back by nabbing one of Misty's Pokémon and trapping her. When Ash got there, they would trap Ash as well and steal Pikachu. They started on the preparations for the plan by making sure they had everything they needed. Shock proof cage, super durable cut proof nets to hold Ash, Misty, and all of their Pokémon, and of course their getaway Meowth hot air balloon which they had to drag back out of the forest they came from and repair.
However while they were dragging the balloon out, Jessie happened to notice a strange device. It looked almost like a helmet, though being out of metal it obviously wasn't for protection. She wanted to try it out without the other members of her team knowing so she said told them she was going to use the bathroom. As she slithered off, she pulled out the device and tried to figure out what it did. The device wasn't a full helmet, as it looked like it only covered certain points on the head.
As Jessie continued to inspect the device, she finally noticed on the back of the device there was a screen. Next to the screen there was a power button which Jessie immediately pushed. The screen lit up as text was displayed and a robotic voice started to speak. "Hello, this is your personal Consciousness Transfer Device." the voice started. "Would you like to transfer your conscious to another person or Pokémon?" The voice asks.
Jessie couldn't believe what she was hearing. This device supposedly had the ability to give her control of anybody she wanted to, human or not. She could become James or Meowth to teach either of them a lesson, she could turn into Cassidy and ruin her reputation, she could even turn into The Boss and take over Team Rocket for herself. However she soon realized this was bigger than Team Rocket as Pokémon were also up for grabs. That's when a truly diabolical thought comes to her head. Years ago Team Rocket had failed to control a Pokémon that would end up causing mass destruction and embarrassment to their organization. A Pokémon that had powerful psychic abilities, one which was fully capable of complete domination over any Pokémon or person, one which just so happened to be residing in a cave right outside of the city where Jessie was at.
Jessie calmly says "Mewtwo" to the device, almost unable to contain her laughter. The device displays the name on the screen before flashing only one possible candidate. She clicks on the image and the device instructs her to put the helmet on. Jessie breathes in before gently laying the helmet on her head. She can feel the electronics doing work on her head before all the sudden everything fades to black.
Jessie wakes up feeling incredibly strange. Opening her eyes everything is foreign to her at first. Forgetting what happened for a split second she looks down and immediately panics at the sight of Mewtwo. She lets out a scream that comes out more as a mannish grunt. It's at this point that everything comes back to her. She looks back down at the body that she is now operating. Jessie had never seen a Mewtwo this close in person, and it was quite the sight. Jessie now had a large tail which was rather heavy and took a lot of effort to move around. Looking immediately down Jessie also saw her feet, which only had two toes in the front and one in the back, though it's not like that one was ever used since her feet were always sticking up, her body basically only needing to stand on the two front toes. She also took notice to her hands, each of which now consisted of three large bulbous fingers. At first this was a bit weird to control but she found herself getting used to just needing to move the fingers in and out.
Suddenly she felt this weird presence in her head. As this presence continued to grow Jessie realized it more as a 'connection' of sorts. She felt this 'connection' with the area around her. Yes, this can only be Mewtwo's signature psychic ability. She is gaining knowledge over how to use her abilities, and she realizes how strong these abilities were. Jessie soon realizes there is no reason to go back to her old body, as no matter how alien this body is to her, the power that comes with it is simply remarkable. It's at this point that she notices the helmet from earlier is on her new body.
"Well there is no more need for this" Jessie simply states, noticing her more deep and manly voice that she has through telepathy. Jessie then removes the helmet from her head and crushes it by simply squeezing her palm. With no chance for this power to be taken away from her Jessie feels unstoppable. "No longer am I the fool who couldn't even capture a measly Pikachu. From this day forth I am the most powerful Pokémon, Mewtwo!" 'Mewtwo' proclaims to the world.
Eager to test their newfound powers the perfect opportunity arrives in the form of a trainer who appears in front of them. However 'Mewtwo' does happen to recognize this person. This is in fact Jessie who is clearly furious.
"What have you done?!?" 'Jessie' states, at which point 'Mewtwo' realizes what is going on.
"Ah, I see. You must be the previous owner of this body. Well as you can see Jessie I am the hotshot around here now." 'Mewtwo' tells 'Jessie'.
"Give me back my body right this instant or be prepared to face the consequences!" 'Jessie' demands.
"You don't realize how little your threats mean without your powers! Although I thought you would already know what you're dealing with, perhaps I need to show you just how powerful I am!" 'Mewtwo' exclaims.
