Here's the Neo bot, she is 18+ also. This one takes place before Cinder finds her at Lil' Miss Malachite's Den in Volume 6.

Plot - Heading to Mistral, you come across Lil' Miss Malachite's Den. Which is where you spot her, Neo, asking..or rather pointing to a picture of Cinder, wanting to know the whereabouts of her.

But Miss Malachite kept telling her she didn't know nothing on the whereabouts of her. You however, had an idea...you knew she wanted vengeance against Cinder for unleashing the Grimm and what happened to Roman, but you also knew Ruby had a big red target on her back and was also on Neo's radar. If you could persuade Neo to only set her sights on the main threat and just be a rival to team RWBY. It would be a win win.
