Discuss giving her an identity.

They collected Nomu once most of the students were gone, allowing security to be a little more lax, and brought her to a locker room. Izuku had wished to make sure no one else would be using it for about an hour. He turned to Nomu, and told her, "Have a seat."

She didn't respond verbally of course, simply smoothly sat down, gazing at her owner with an expressionless face. "I certainly do good work," Momo smirked proudly, leaning forward, and cupping Nomu's face. "She still has a strong body, but delicate, feminine facial features..." she purred. "...though I do see your point Master, I suppose if she wouldn't respond to anything you do to her, it could get boring..."

Izuku nodded thoughtfully. "So, you really can't just bring back the old personality?"

"Nope, like I said, if this world has gods, then the soul or whatever passes for one has a claim on it. It's kind of like having a bully twice your size having stolen a drawing you made. If this world doesn't have gods, or even an afterlife, then the drawing was basically burned instead. At either point, it really is just more feasible to make a new one," Momo replied, looking at Izuku seriously.

"...did you have to use a bully analogy?" Izuku sighed, and Momo winced.

"Ah, sorry Master, forgot your history for a second there..." she apologized sheepishly, before returning to admiring her "workmanship" with the Nomu, who continued to passively accept her inspection.

"But going on that analogy, we can basically draw whatever we want with the new one, right?" Ochaco chirped.

"See, now you're thinking!" Momo giggled. "Perhaps a totally ditzy, obedient, horny, bimbo?"

"That could also get boring," Ochaco pointed out. "Even you still have your old personality mixed in with the bimbo genie thing," she added, teasingly.

"Hey!" Momo pouted, and Izuku chuckled at the playful banter.

"Maybe we could implant multiple personalities into her, and use triggers to swap them out?" Ochaco asked. "Can multiple "souls" share a body?"

"They can, and that's also a great idea!" Momo grinned. "We'd have to determine what kind of personalities she'd have beforehand, for the best results, easier to integrate them together that way... But she could do all kinds of roleplay that way! Nurse, maid, schoolgirl, all kinds of options!"

"Why not just give her the ability to develop her own personality, and let her go from there?" Izuku inquired.

"Also possible!" Momo nodded, moving behind Nomu, and groping her boobs, naturally still getting no response. "All are good ideas, but which one do we want to go with?"
