Gabby Gonzalez Gabriella Lucia Fernanda " Gabby " Gonzalez ( COMIC : " The Good Companion " ) 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 . Gabby unknowingly possessed supernatural abilities which tapped into her deep interest in art . Because of this , Gabby ' s notebook would often contain real - time documentations of her adventures ; even when she was not around it . Gabby was also able to summon butterfly - shaped apparitions which she would use for various purposes . Biography . Youth . 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 realised that the whole story was a hoax made - up by the counsellors . ( COMIC : " Cindy , Cleo and the Magic Sketchbook " ) Meeting the Doctor . 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 . Realising 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 . ( COMIC : " Revolutions of Terror " ) 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 binary apprentice . Despite the apprentice trying to kill them , Gabby ' s sincerity won her the trust of its female aspect , who gave her a connection to the quantum sphere . Using this connection , Gabby could use the residual block transfer energy , creating sometimes butterflies and sometimes levitating talking mouths . Gabby could not always control these abilities . Zhe believed that they would fade away leaving only heightened awareness and occasional flashes of abilities . After this trip the Doctor invited Gabby to stay on in the TARDIS . ( COMIC : " The Arts in Space " ) Gabby encountered the Weeping Angel s 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 Shreeker s , 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 . ( COMIC : " The Fountains of Forever " ) Personality . Gabby was a generally happy and cheerful individual as well as an aspiring artist . She wanted to attend college and was frustrated that her father wanted her to stay at home , but ultimately loved him and the rest of her family . ( COMIC : " Revolutions of Terror " ) Gabby was childhood friends with Cindy Wu , but was unaware that Cindy harbored romantic feelings towards her . 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 " ) Abilities . After an encounter with the Apprentice , Gabby was infected with an organic block transfer matrix . Though it remained hidden for a while , she was able to access this ability following a run - in with Ebonite . Thanks to this power , Gabby could summon butterfly - shaped constructs of light for various purposes such as blasting them at people , forming protective shield around herself or even to levitate herself and others . In a potential future , Gabby ’ s powers evolved to the point that she became a time sensitive transhuman capable of creating an entire world using her block transfer abilities . This future version of Gabby could also travel through time and space at will , project herself across multiple locations and time periods simultaneously as well as fire blasts or electricity as a form of attack . Behind the scenes . Throughout various alternate covers of " " , 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 sometimes illustrated with a darker palette , on occasion 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 .
