Anime Assaulters Xeno Omake Para-Episode 002: Don't Drink the Juice!

Shion smashed her computer keyboard on Mo-mo's head as they got into another fight and reeking havoc in the house. Looks like Athrun and Cagarii won't be happy when they come back home.
Hell, they won't be happy at all...because Kos-Mos drank Shion's mytery liquid, and shrunk down into a baby state, and cried.
"Crap," Shion said.
"Bah-gah!" Kos-Mos cried.
"So..." Mo-mo said.
"You know baby care?" Shion said.
"No," Mo-mo said.
Kos-Mos crawled to Shion and held onto her leg.
"Well, you're the new mommy," Mo-mo snickered.
Shion picked up Kos-Mos, "Shut up, Mo-mo."
"Boo..." Kos-Mos said.
Mo-mo pinched Kos-Mos's nose and began pulling.
"Quit it!" Shion said and punched her in the face, and knocked her down the stairs.

Athrun and Cagari came back from the supermarket and caught Mo-mo falling down the stairs. They then turned their eyes upstairs as Shion, holding Kos- Mos in front of her, looked down. Then Shion realized the trouble she's in as she turned her eyes at Kos-Mos.
"SHION!" Athrun and Cagari shouted.

"Shion, what were you doing?" Athrun said.
"Just computer gaming," Shion said.
"We are not mad at you," Cagari said, "But...WHY IS KOS-MOS A BABY?!"
"Well...isn't she cute?" Shion said, holding Kos-Mos up.
Cagari smiled, "Well..."
Mo-mo leaned over to Shion's ear, "What are you doing?"
"I don't wanna get grounded," Shion whispered.

-Character Bio File 02-

Mo-mo de Zala

Originally an android designed for espionage, Mo-mo has joined the fight against the evil "Shion" along side with Athrun and his team.

At the end, after freeing the spirit "Pandora", she and Kos-Mos are granted one wish from each of them. Mo-Mo said that she wants to be human, and Kos- Mos says she wants to be Mo-Mo's big sister. This of course, pissed Mo-mo off, since Kos-Mos SHOULD have been the younger sister for being so childish.

She wears the same black clothing as she did in Xenosaga I, but with a more taller, adult build
