Ajo makes up 80% of the apathy and bad attitude of Vron's Tracking Team. Bothersome but benign circumstances led to Ajo being stuck on this seemingly hopeless mission. But at the very least Ajo is thankful she is alive and doing pointless busy work, rather than where the military top brass had planned on sending her.
As an immigrant from the colony of Tamlin Ajo's overall appearance (mainly her tail) and personality is off-putting to most homeworld Taikese, and she is on the tall end for her kind, almost pushing 10 feet.
Ajo comes across as combative and cruel, and is the most likely to resort to murder as a solution to a problem. Vron is terrified of her (although he does his best to hide it) and Malik is cautious.
But even though Ajo seems cold and vicious she has a soft side. She is generally kind to Malik and even feels some sympathy for Vron (though she wouldn't say it to his face) and there are people back on Taikos she deeply loves and misses.
A life of trauma makes it a little difficult for Ajo to feel comfortable sharing these tender emotions, but after a year of getting to know Vron and Malik she's been steadily opening up.
In regards to gender Ajo doesn't like to make too much of a fuss about it. She/her, they/them, and he/him are all acceptable pronouns of address.
