Gabby Gonzalez

Gabriella "Gabby" Gonzalez was a Mexican American companion of the Tenth Doctor. She travelled with him shortly after he lost Donna Noble and, like Martha Jones, was originally promised only one trip in the TARDIS.

Biography
Gabby was childhood friends with Cindy Wu, a Canadian immigrant. 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 realized that the whole story was a hoax made-up by the counselors. (COMIC: Cindy, Cleo and the Magic Sketchbook)

Gabriella worked at her father's businesses, a Mexican restaurant located at Sunset Park, New York City and a laundromat, while attending night school for accounting and getting straight A's, but she really wanted to be an artist. She was at the laundromat with her best friend Cindy Wu when all of the washing machines shot water everywhere. On the subway home from class, she was attacked by a Cerebravore and met the Doctor. She used a mirror to reflect Cerebravore's psychic energy, defeating it.

In the morning, she was working at the laundromat when the Doctor appeared again. He explained that the attacks were by Cerebravores who were not from Earth he was searching for their entry point to this world. Gabby helped him find and destroy the interdimensional bridge in the laundromat used by Cerebravores and then, during Day of the Dead celebrations in Green-Wood Cemetery, she helped him defeat the small party of Cerebravores already on Earth. Realizing that the Doctor could teach her more than any college, Gabby begged for the Doctor to take her with him. He initially refused, but agreed eventually, for just one trip.

The Tenth Doctor took Gabby to the Pentaquoteque Gallery on Ouloumos, where she was left in awe by the entire experience. Wanting to visit Zhe Ikiyuyu, they went to her private retreat, where they were attacked by the Apprentice. She ended up making friends with the version of the Apprentice that was with her, which caused her to have temporary side effects such as heightened awareness and flashes of abilities. The Doctor, Gabby and Zhe defeated the Apprentice, with the Doctor inviting her to stay on the TARDIS. (COMIC: The Arts in Space)

Gabby encountered the Weeping Angels in World War I. While there, she met Jamie Colquhoun, instantly becoming smitten with him. The TARDIS was temporarily taken by the Angels, who picked off the soldiers one by one to feed on their potential energy. Once the Angels were trapped underground, Gabby bid farewell to Jamie, knowing she could not be with him. (COMIC: The Weeping Angels of Mons)

Asking to be taken home briefly to check on her family, Gabby had her cell phone upgraded to allow her to call the TARDIS and text the psychic paper. She attempted to call her friend Cindy Wu, who screamed and hung up. Gabby visited her home, finding everyone was beginning to scream; the entire city was sounding loud. Luckily, the Doctor gave her sonic earmuffs to block out the noise; it turns out sentient whales made of sound known as Echoes where being hunted by Shreekers, who planned on weaponising the Echoes abilities. With the Doctor incapacitated, Gabby used the sonic screwdriver to turn the Empire State Building into a transmitter to overload the Shreekers' ship and force them to flee. (COMIC: Echo)

While the Doctor went to investigate something benign, Gabby decided to go looking for Cindy again. She ran into Cindy, who demanded answers. Gabby showed her her journal and told her about her adventures with the Doctor. However, Gabby was disbelieved. Getting a bad feeling, she checked her phone, finding messages from the Doctor that said he was in terrible pain. Following the address, Gabby ended up in the home of Dorothy Bell, where the Doctor explained something terrible was going to happen due to Dorothy messing with a Quantum harvester.

Behind the scenes
Throughout various alternate covers of Doctor Who: The Tenth Doctor, Gabby has been represented alongside David Tennant through various models. These models, however, have not been credited or identified, and one model is never used more than once. Fittingly, Gabby's appearance in the comic has also been slightly inconsistent from artist-to-artist. Even Gabby's skin colour has never been pinned down. While she is often illustrated with a darker palate, occasionally her skin will be more pale than even Cindy's.

Gabby is notable as being the first known companion of the Doctor to be of Hispanic descent, both in-narrative and in the real world.
