Weeks passed since the last experiment, with 18 back to normal and in her room, reading a magazine as 21 continued her research.



At first 18 was reluctant to try anything, especially after she had spent the better part of a week turned into a kangaroo and being poked and prodded by her overly enthusiastic friend. Even so, the Android felt herself growing bored.



“I wonder if this timeline’s West City has anything I can do for fun...” 18 pondered the fact, considering that the timeline she was in seemed to be devoid of Goku or his friends for some reason. She quickly thought of the World Martial Arts tournament and the prospect of easy money, only for the thought to later disappear from her mind. As easy as it would be, she did want some challenge.



As 18 sighed and turned another page in her magazine, she heard a knock on her door. “What?”



A second later, 21 peeked her head in. “Oh, 18, I-”



“No.” 18 flipped a page in her magazine, not looking up.



“But it’s really-”



“Pass.”



“If you’d just let me finish a sen-”



“Later.” 18 insisted as she continued to read.



“Ugh.” 21 pouted. “What if I promise you I’ll do one thing you want? Whatever it is?”



18 mulled it over. “We go shopping, and you carry the bags.”



“If I must. But don’t you ever want to do something else?”



“Take out my pent up anger against Gero on others, terrorize humans, and go joyriding...As long as it isn’t a drawn out roadtrip,” 18 answered in a deadpan manner.



“...We really need to get you some normal hobbies,” 21 sighed. “After this though.”



“Fine. So is it more of that serum or-?”



“Nope! A fragment of a curious nanomachine I happened upon.” 21 smiled. “It’s the Big Gete Star, or at least a portion of it I reprogrammed.”



“So, what, is it a system update?” 18 asked.



“Something like that. It’ll make you stronger, sure, but it could do more. All we need to do is have you hold it and see.”



“Alright,” 18 replied, feeling as though a boost to her power would be welcome. Standing, she went over and took it, before she felt it begin to crackle, spreading and expanding as it integrated with her systems, expanding her power. “Whoa. Now this is something I can get behind.”



“Yes, but let’s make sure it can at least execute one of the forms I programmed,” 21 said before revealing a hand held device, scrolling through options on the screen. “Ah, this one!”



18 looked confused, before she felt her body begin to grow outwards, expanding and becoming wider. There was a strange stiffness as she noticed that nanomachines were everywhere, all over her body and even in her clothes.



It only took a few seconds before she realized that she had become cubical in shape, almost like a box, her face stretched and morphed to the top of the front facing part of it, while she noticed something, a strange sensation near her belly button.



18 tried to look down, but by then she had no head to speak of, or even arms or legs. Instead, a large, see through glass door, circled with metal appeared, an an inner chamber.



18 tried to move, but couldn’t, instead she felt heavy, despite her exterior remaining fleshy, her clothes still somehow adhering to her body. “What is this?!”



“The washing machine function. It preserves your biological nature while making your systems resemble and function like a washing machine,” 21 said before kneeling and opening the glass door, revealing the washing chamber within. “This confirms you can replicate devices I programmed into the Big Gete Star.”



18 rolled her eyes. “Great, now if you’re done exercising your internalized misogyny, can you change me back?”



“In a minute. I got some jelly donut stains on my coat, and I really need to get it out, so...” 21 then took off her coat and tossed it in.



18 felt the door slam before 21 pressed a button on her pad. Seconds later, she began to fill with water. “H-how?”



“Oh, the system lets you absorb ambient hydrogen and combine it with your oxygen to synthesize water in the chamber. The nanomachines then clear out the stains, destroying them and then the wa-”



“Enough!” 18 shouted. “Just change me back already!”



“After the rinse cycle~!” 21 laughed as 18 felt the water slosh and her body rumble.



Muttering curse words and shaking, 18 was ready to pay back 21 later...
