[quote]As suggested, a military rank could work if it aligns with her backstory.[/quote]She was an explorer. In the MOS prequel comic she was a Captain. Could also use the name of the medal she got Star of Rao.

[quote=@Archmage MC]Super Lady. I like the word 'Lady'. Or something of that kin. xD[/quote]Same reason as Superwoman/girl. She doesn't want to be in her descendant's shadow.
