Samus Aran was standing on the surface of a planet that seemed un inhabited by lifeforms, but only plant life. She was sure to make sure her ship was locked up, and she wasn't tracked. She had escaped from a mad space scientist who preformed an experiment on her, and now, she was working to control something within her. The scientist had a fascination with animals from Earth, mainly mammals. So, she wanted to see if she could make pets from other creatures by messing with their DNA. And Samus, she got bunny DNA. However, it didn't work all that well, and Samus was put on hold. Samus then used the opportunity to escape.
However, she also stole the analysis from her experiments, and she found a little flaw. She would be subjugated to a transformation every month, and it would not be one where she could control herself. It would happen when she was shown in moon light. However, sometimes the animal comes out on its own, and Samus was trying to figure out how to get control of this thing.
Now, Samus was in her Zero Suit, taking in the air, and waiting for the change to happen. She had no communications right now, and was prepared for a few months just in case. As Samus looked around, she tracked her findings in a log she made, and all that there was.
Samus then said, "This had better be worth it. I am not going back as an animal. I would be a much tastier snack to many villains I face."
Samus then shook at the thought. She then saw the sun setting, and took a deep breath.
"Okay, just need to wait," said Samus.
She stood there for a while, and felt a tingling inside her. Her hands started to shake, and she was sweating a bit. Samus looked up at the Full Moon, and was panting hard now. She then looked around, and felt something in her mouth. She felt it, and her two front teeth had popped into giant bucked teeth.
Here we go! she thought to herself.
Samus lifted her hand up, and saw that it started to stretch out a bit, before ripping the glove apart, and revealing a paw with blonde fur. Her other hand had followed suit, and she felt her whole body starting to change a bit. She looked at her chest, and it started to get flatter! Her back started to hunch over a bit, and Samus' nose cured up, revealing her nostrils. Samus' upper body started to get wider, and stretch out her suit!
Am I growing!? thought Samus, No! I didn't think this would happen!
Samus then felt a pain in her ass, and looked down. Something was forcing its way, and popped out with a boing, revealing a cotton tail!
"AAAA WOOOOOOOOOOOOOOOOOOOOOOOO!"
Samus' boots started to stretch out, and burst open, revealing giant rabbit feet. Her legs got thicker, ripping the legs. Her hair fell out of it's ponytail as it receded, and turned into fur. Samus felt her face bloat up as her mind started to slip. The stubs that were her human ears popped into floppy rabbit ears, and she started to gain more mass, as the suit ripped from the neck down.
Finally, the beast ripped off the suit, and the rabbit panted. It took off in a flash, leaving the suit scraps behind. The rabbit went around, eating all the vegetation it could find, and not leaving much left.
Next morning, Samus awoke in her ship, naked, and no memory of what happened. She then remembered the report.
"Oh no, please no!"
Samus got up, and while the inside only had mud tracked inside that showed Samus slowly changing back to human, the outside was totaled. Scratches, the hatch torn in half, and the thrusters smashed to bits. It seemed she was stuck here for some time.
"Damn it," she said, "I can't believe this."
Samus then went to the closet, to find some clothes that she could wear while her suit was still recharging.
