Pyrrha Sancartia

Pyrrha Eutola Sancartia is a villainous mastermind behind many of the games events. In Act 1, she manipulated things so Aegis would arrive on Mars and Ken Surutoga would awaken Lilith. She's also the apparent leader of a group that includes Zen, who hypnotized and later kidnapped Vee.

She pilots the Bael Gundam, and was strong enough to take Haru Yamada's strongest attack, then counter by one-hit KOing her at the end of Act 1.
