Una Baha is the niece of the weapons inventor, T.K. Baha. She is never encountered in person, but offers some limited interactive contributions as a remote character communicating through the ECHOnet.
thumb|80px|ECHO iconUna is first encountered via ECHO during the side-mission Uncle Teddy, during which T.K.'s weapon blueprint must be found in his secret lab and then mailed to either Una or Hyperion. She offers "the first gun TK Baha made for her," the Lady Fist, as a reward if the blueprints are sent to her.
