Name: Zeta / Zeta 8
Full Name: Zeta 872496
Portrayed by: Rula Lenska
Notes: Zeta is the 23rd century version of a mad aunt. Except this is Sigmasix's mad aunt.
Head of Zeta Corporation and hell bent on power, she largely thinks she is untouchable due to her power and influence within politics and industry. She takes it upon herself to get revenge for her nephew (Sigmasix) being imprisoned for illegal time travel, which seems more about a show of power than it does for getting justice for Sigmasix.
Trivia: Played by the excellent Rula Lenska, former wife of Dennis Waterman (Minder & New Tricks).
