In the case of character ages, if Athena is made to look about 12-14 but she is mentally as mature as an adult and talks/acts that way and she is well over 20 years old would she be considered a character that can be apped?

I was also unclear about the condition she would be in upon arrival. She is a robot in canon, would she need to be humanized to be brought into the game or could she stay as a robot that can completely pass as human and keep all of her special skills? I was confused by the humanoid appearance mention and wasn't sure!
