Vega was the princess and now is the current queen of The Cluster and estranged daughter of the former Queen Vexus. She had befriended fugitive Jenny, after Jenny was able to escape out of Vexus' clutches. She and Jenny are similar as she is also a teenager and has robot friends that look just like Jenny's friends. Originally Vega was unaware of her mother's evilness and believed her when she framed X-J9 for stealing all of the golden computer chips. However, after discovering that all the computer chips were actually in her palace, she realized that Vexus was behind the whole thing. She and Jenny both fought her and got her to admit the crime, Vexus was later dethroned as queen and Vega took over. She asked Jenny to stay in Cluster Prime, but Jenny claimed that she belonged on Earth. Vega understood, but she wanted Jenny to come visit her sometime; Jenny happily promised to do that when she could.
She has dark burgundy "hair" with 2 thin black ends sticking upward. Vega's eyes are seen as yellow colored with 2 black dots for pupils, but closer inspection shows they are green. She has a thin "V" shaped chest plate with a yellow circle on it and a thin black waist. Her arms are striped into fours with thin black fingers. Vega's skirt is burgundy and green with burgundy "boots."
When Jenny came to Cluster Prime, Vega saw her as a friend, even when she figured out that Jenny was X-J9.
The right hand side of Vega's hairdo acts as a mobile phone.
