No information

Tia Marvinas is the oldest member of The Sparticle Tribe and is one of the two leaders of The Ranchers. She is first seen babysitting Frankie in Sadiq's house.


Tia cares a lot about her appearance, ander, not as useless as she can seem, and proves this several times. She seems to be very over protective, especially with Liam and Frankie. She is the ex- best friend of Holly as they broke up in Series 2. She got jealous when Serena became best friends with her.


Tia is a tall girl with brown eyes and long, light brown wavy hair. It is often in a side part and flows over her shoulders. She is usually seen wearing a blue denim jacket, a pink print top, skirt and high-heels in series one while in series two she has been spotted with a dark blue hoodie, flower-print dress with belt, navy leggings and pink heel boots. 

She owns quite a bit of jewellery, though she has only talked about two necklaces, one which she gave to Frankie when she thought she would disappear into a parralell dimension but then took back and the other that her father gave to her before he vanished with all the other parents. Tia wears this necklace all the time.

Tia cares about her appearance a lot and would be classed as a girly girl.
