A few more female Heroes

[Thalatta]

These could be considered:
-Artemisia I for Persians (or Carians, if part of the game at some point): naval commander. The one from the battles of Artemisium and Salamis. 
-Artemisia II for Persians (or Carians): naval strategist and medical researcher. Sister/wife of Mausolus, ordered the construction of his tomb: the Mausoleum at Halicarnassus.
-Lǚ Mǔ for Han: rebel leader that played a role in the restoration of the Han dynasty.
-Teuta for Illyrians: not a playable faction still (eventually?), but since Gaia's units being more challenging has been mentioned, they could even have Heroes, and Teuta would be compatible with Gaia's piracy units (although I'd name them differently than Gaia, and reserve that for basically abandoned things).

Artemisia - Recherche Google  seems this heroe is not emblematic

Artemisia II : she @#$%s with her brother but she built a good building with a big aura so why not , she is more greek than persian (she is carien as you said)

Lǚ Mǔ — Wikipédia she has a low history frankly

Teuta — Wikipédia no opinion , this civ will never be in 0AD i guess

Artemisia I is well known and was held in high regard even by those sympathetic to the opposite side. That you need to Google her and instead get a plant, thus incorrectly concluding she was not "emblematic", only exposes your own ignorance. Try reading Herodotus, or something actually substantial.

Artemisia II's marriage could have been a non-physical arrangement for all we know, but your comment is utterly irrelevant, not only by itself but also given the period, culture, and considering we have plenty of Ptolemaic royal heroes anyway. What I count is allegiance, not ethnicity, which is what matters in combat.

Regarding Lǚ Mǔ, I really wonder who are you to say that the first female rebel leader in Chinese history has a "low history", do you conclude this by the length of the quoted French Wikipedia article your extensive research is based on? Or can you share with us which Chinese history books on the matter you have read?
