Cindy Wu

Cindy Wu was a friend of the Tenth Doctor's companion Gabby Gonzalez, and became involved in many of their adventures, eventually becoming a companion of the Doctor alongside Gabby.

Early life
Cindy was born in Canada. (COMIC: The Wishing Well Witch) At some point she immigrated to Brooklyn, New York; where she became childhood friends with Gabby Gonzalez.

When the pair were ten or eleven, they went to summer camp at Echo Lake. During one night, the pair were told a campfire story about a Rabid Raccoon which would stalk the camp grounds looking to attack anyone who got too close. Gabby and Cindy spent the night cowering inside their tent, shining a flashlight out into the dark. Eventually they fell asleep. The next morning they realised that the whole story was a hoax made-up by the counsellors. (COMIC: Cindy, Cleo and the Magic Sketchbook)

She said her Dad loved his children, but "the weight of his expectation would crush you." She was going to college for social science.

Meeting the Doctor
One day, while Cindy was hanging out with Gabby in her father's laundromat, all the washing machines malfunctioned and exploded around them. The two girls cleaned up the mess. Later, Cindy became possessed by a Cerebravore and tried to break into the laundromat, where Gabby barricaded. After Cerebravores were defeated, Cindy was invited to the Gonzalez family dinner in honour of the Tenth Doctor. (COMIC: Revolutions of Terror)

When Gabby returned from her travels with the Doctor, she told Cindy about them. (COMIC: Echo)

Initially, Cindy attributed these stories to Gabby's imagination. When Gabby received a disturbing message from the Doctor, Cindy insisted on following her to the Upper East Side and found herself in Dorothy Bell's apartment just in time to witness her rejuvenation.

Encounter with Ebonite
Shortly after the Anubis incident, Cindy met Jack Harkness and was pulled into Ebonite's Arena of Fear. (COMIC: Arena of Fear)

Initial travels
The Tenth Doctor brought Cindy and Gabby to a conclave along the road to Parthia in 111, where they discovered a plot by the Zoroniss to take over the world. Cindy was disgusted by the portion of their plan which involved incubating Roman soldiers with Zoroniss eggs and was willing to fend them off with her bare fists. (COMIC: The Long Con)

Roscoe & Sutekh
During a stop-off in 1930s New Orleans, Cindy fell in love with Jazz musician Roscoe Ruskin. (COMIC: The Jazz Monster)

As the MuWu
Cindy, Gabby and the Tenth Doctor would spend many days together in the Garden of Osiris. Cindy would grow very close with Noobis, who eventually admitted that he wanted to leave the Garden of Osiris to travel with the Doctor.

While in the Garden, the team were attacked and absorbed by a consciousness from an alternate universe which placed each of them into fictionalised virtual environments. In the new reality, Cindy was in a romantic relationship with Cleo Hunsicker and had a black dog which resembled the real Noobis.

On one evening, Cindy and Cleo lost track of the dog as they headed for the subway. As Cleo entered the train, the dog pulled Cindy off at the last moment, revealing itself to be Noobis in disguise. In their few moments of open thought, Noobis helped Cindy remember the truth of their situation and helped her escape the virtual reality into the real world. Cindy awoke to discover herself connected to a archaic yet developed piece of technology, surrounded by dead bodies which closely resembled her. Disconnecting herself from her constraints, she began to investigate the complex. (COMIC: Breakfast at Tyranny's)

Cindy was kidnapped by a being resembling a TARDIS and brought to ancient China. (COMIC: Sharper Than a Serpent's Tooth)

Personality
Cindy's most close and personal relationship was with her best friend Gabby. The pair had been friends since their early teens. (COMIC: Cindy, Cleo and the Magic Sketchbook) Dorothy Bell noted that the two showed incredible loyalty to each other, and wished that she held something similar. She also told the Doctor that they needed space away from him to find themselves. (COMIC: Old Girl)

After Gabby left, Cindy missed her deeply. While she initially diagnosed this as jealousy, she eventually came to the conclusion that she could not bear the thought of not having Gabby around. This was why she eventually decided to join Gabby in the TARDIS. (COMIC: Old Girl)

Cindy secretly held romantic interests for Gabby, and later for Cleopatra Hunsicker; but she would eventually come to the conclusion that both women were "uninterested." (COMIC: Breakfast at Tyranny's) Gabby would explain to Cindy that while she did indeed love her, she wanted Cindy to realise that she didn't need their relationship to survive. (COMIC: Old Girl)

In the simulated reality created by the Wraiths, that version of Cleo was dating Cindy. When Cindy began to realise that the world was fake, the fake Cleo protested Cindy looking for Gabby; noting that "she's not interested," further claiming that the real Cleo showed off the body language of someone who was.
