(OOC: Gee, insert SSBB's song version of "Encounter" here. o.o) Great idea, and sure, no problem. I think that fits very well here.

"But-" then when Rita saw the determined look in his eyes, she would no longer reject his involvement. She understood all about doing what you felt strongly for.
Now she had to do everything she could to make sure this creature doesn't pay for staying with her. She couldn't fight her best in this beaten body of hers. She knew she wasn't fully ready to do something like this, and she found it very scary to be like that, but those things didn't matter now. She had to try, to do everything in her power to keep them both safe.
"Wish mode!" she called. White rings of energy started on her feet. They ran up her body, changing it. Her back legs were smaller but more muscular and her front legs were no longer legs but arms, with razor sharp claws at the end. Her body stood straight and her neck shortened. Her face narrowed and her flat teeth were no longer flat, and now filled her mouth.
She roared fiercly and charged at one of the primids. This one had a sword and it swung down at her. She reached up and blocked with her claws. The primid applied more power in this game of force and the pressure on her claws made them start to bleed, but she didn't even notice the pain.
She roared even louder and spun her arm around suddenly while pincing the blade between her claws and the primid lost its grip on the sword as it flew away and hit the ground with a thud. She wasted no time and pounced on it. It kicked her hard to knock her off but she was merely shoved back a little and she bit into its arm. She tightened her grip and the primid could not get loose. She smiled evily as she licked up the blood that was coming from its arm.
She eventually let go so it would try to run, but as it stood up, she grabbed its throat and shoved it against a wall. She was smaller than it, but she knew nothing but aggression right now. A good blow to the stomach would cause even more gasping for breath, something it couldn't even do very well now.
With her free arm, she curled her claws up in a fist and pummeled its lower abdomen until it was too low on oxygen to sustain motor movement. As its body started to go limp, she actually let go so it wouldn't die just yet, and then repeatedly slashed into it deeply to cause even more pain, and the whole time, she seemed to be enjoying this.
Sharpteeth are born with very strong instinct and agression. Flatteth are more peaceful and doen't have such intense tendencies. Since sharpteeth have them naturally, they learn to control them and use discretion, so they don't get berserk in battles.
But Rita, like any other leaf eater would, currently has extreme difficulty switching from her own mindset to another one that is so contrary to it. She doesn't naturally have such instinctive behavior, so to get so much all at once would completely overwhelm her, and she would lose herself in the process.
She couldn't control this power yet, but she could always see everything she was doing, and she cried inside the whole time she was like this. She only changed in a dire situation where more fighting power was needed. Although she wanted to more than anything, as of now, she hasn't learned use her power and her mind at the same time.
Someone who cared for her like Mallow or Jigglypuff would get through to her heart and she could overcome it and return to her senses and change back. But they were both gone and she had acted rashly now because her judgement was clouded by worry. Her body could keep this up for a very long time, but her feelings screamed in anguish. She really needed help, but she didn't know anyone else who cared about her that was around.
