Regina appears offscreen during the mission Defend Testing Grounds. She can then be hired as a consort in the following missions:
An aggressive combatant who pilots an AC with a variety of high power weaponry. She likes to put on showy battles, but her AC's limited ammunition stores mean they have to be concluded quickly. She ran away from home to follow in the footsteps of her father who is also a Raven.
The only Threat Regina poses is to ACs too slow to dodge her primary weapon. The grenade launcher is devastating but it is the weapon that should be feared, not Regina. Her Piloting skills leave quite a bit to be desired and she is not very swift. Combine that with relatively weak armor and poor accuracy and the battle holds little challenge.
The name Echidna refers to a spiny anteater, belonging to the family Tachyglossidae in the monotreme order of egg-laying mammals.
- Regina is hinted to be the daughter of the Raven Trooper because of their similarity in emblem and they are partnered in the Extra Arena. Regina's bio also states her father is a Raven and Trooper's bio states his daughter ran away to become a Raven.
- Despite being ranked E-19 in the Arena, the Extra Arena is lists her as a B-ranked Raven.
