Aile

Aile is a main character of Mega Man ZX, and the female counterpart of Vent. She can also use the powerful artifacts known as Biometals to defend herself and others from Mavericks. She is a tomboy that appears to be between 11–15 years old in Mega Man ZX and is 18 years old in Mega Man ZX Advent.

Personality
In Mega Man ZX, she seems to be more lenient towards others, excluding her foes and is a bit more compassionate than Vent. In Mega Man ZX Advent, however, her personality shifted a bit. As she got older, Aile seems to have become more professional with whomever she meets, as shown when Grey was blunt and disrespectful towards her when introducing himself. She also seems a bit more cocky compared to Vent, but she's still caring.
