What do you think made him what he is, Batman? Childhood trauma? Some kind of breakdown? He never speaks about it.
~ Young on the Joker.

Dr. Penelope Young is a major character in the Batman: Arkham videogame series, appearing as a minor antagonist-turned-supporting character in Batman: Arkham Asylum, as a background character in both Batman: Arkham Origins and Batman: Arkham Knight's prequel DLC episode Batgirl: A Matter of Family, and as a posthumous character in Batman: Arkham City. She is a hardworking and obsessive scientist who temporarily works with the Joker to develop the TITAN Formula.

She was voiced by Cree Summer, who also played Elmyra Duff in Tiny Toons, Hyena in Disney's Gargoyles, Mercy Graves in Superman: Doomsday, Penny Gadget in Inspector Gadget from Nostalgia Critic, and The Little Girl from Robot Chicken.



Penelope Young was born on January 19, 1975. She would later attend Gotham University where she studied psychology, graduating with honors and achieved a Ph.D. in psychology.

She later became a psychiatrist professionally and first started helping people out of her home in the Lacey Towers apartments.

Batgirl: A Matter of Family

Around the same time, she was employed at Arkham Asylum, Young began working for the wealthy oil baron Edward Burke to prescribe medication and help to his 5-year-old daughter Katie, who had been diagnosed with cancer. During this time, she and Burke began working long-distance with a therapist and associate her's named Jack White and a doctor named Harleen Quinzel, who were in fact the Joker and Harley Quinn. They planned to give Burke the idea to construct an amusement park based on Katie's drawings and use it as their new base of operations.

Jack White/Joker suggested Katie be put under experimental medication, to which Young agreed as she saw the little girl as the perfect test subject for the drugs, as well as other ideas she had regarding cures for criminal insanity. When White suggested she up the dosage, Katie's condition worsened and the girl died of drug overdose. Jack White later ended up convincing Burke to take his own life with suicide pills, which turned out to be Joker venom. After Katie's death Young continued to use the medication and find ways to perfect it.

Later, after Quincy Sharp reopened Arkham Asylum and rehired Young, she continued work on a new and experimental formula called TITAN, which combined elements of her previous experimental drugs and new compounds to potentially create a cure for criminal insanity. Funded by White, she managed to smuggle Bane into the Asylum and forcibly extract the Venom from his body, leaving him in a weakened and tortured state while she studied the effects of Venom on the human body and decided to include it as a part of the TITAN formula. She also used plant-based chemicals from Ivy's plants to enhance the formula.

Many doctors, guards along with other staff worked with Dr. Young on project TITAN but none of them knew Young's full plan and knew nothing about the full extent of her work or treatments. Yes kept it a secret form her fellow workers none of the staff liked that Young was keeping secrets from the rest of the staff. But they respected her and trusted her despite that they knew nothing about her deal with Joker or what the TITAN project really was and not knowing that Bane was Patient X.

For 2 years, she constantly worked on the formula with her research developments at the Botanical Gardens. After several patient interviews, she decided that the Joker would be the prime candidate for her experimental cure. She first tested the formula on a prisoner from Blackgate Prison, who mutated into a horrific monster. It was around that time that she discovered Jack White was the Joker, and he planned to use the TITAN formula to create an army. Horrified by this, she transferred the funding back to the Joker and refused to work on the project. It was then that the Joker decided to allow himself to be captured so that he could take over the Asylum and complete the formula himself.

Arkham Asylum

As the Joker was taken into custody and escorted into Arkham, Young watched in the Cell Block Transfer Corridor as the team went by. Joker made threats towards her, but she remained protected by guards. Young watched and listened to Joker terrified secretly knowing the real reason why he was back in Arkham and knew of his plan. As Joker made his threats to her he told Young that they had some catching up to do. After Joker was wheeled away Young regains her composure and confidence then forcefully tells the guards to take her back to her office. Young tries asking Batman if he knows what made the Joker become who he is. After that Young stands there silent and shows bravado when Joker is no longer around.

After Joker's takeover of the Asylum, he had his goons and Harley Quinn hunt down Young and corner her in an office, where they planned to interrogate her. She was saved by Batman, but soon left with Aaron Cash to Arkham Mansion to retrieve her notes before the Joker could get ahold of them.

Batman later discovered and battled Bane, who revealed Young's role in the TITAN project, referring to her as the "bruja", or "witch".

Despite experiencing obstacles and the Joker's men, Young managed to get her notes and flee, hiding them in a book in the library before being captured by the Joker's men and taken to him. After bringing Young to Joker the henchmen being talking among themselves mentioning that they believe Dr. Young knew what was going on or what was going to happen actions, reaction and behavior. Joker, angry that Young did not have her notes, handed her over to Victor Zsasz, whom the Joker had ordered to torture her for her information. She was saved by Batman.

Young proceeded to tell Batman everything she knew about TITAN and the Joker's plans, and her experiments in the Botanical Gardens. She then went to Sharp's safe for the access codes that would open the gates and let the innocents escape, but found out too late that the Joker had booby-trapped it with a bomb. Batman managed to survive the explosion, but Young was killed in the blast.

Later on, during a hallucination caused by Scarecrow's Fear Toxin, Batman sees Arkham Asylum run by the inmates, where Young is among the prisoners at the twisted Asylum.

Aside from Young appearing in Scarecrow's hallucination servel surviving staff members ask if Dr. Young is ok Batman informs them that she is dead. The surviving works are shocked to hear that Young is dead some of them say if the inmates killed her then there's no way they will survive this night.

Arkham City

In Arkham City, Batman aids Bane in destroying the remaining TITAN containers that the Joker smuggled off of the island. She later revives some posthumous justice after Joker dies as a result of overdosing on the TITAN formula.

Aside from some of the TITAN formula making it off the island and Joker slowly dying because of the formula created by Dr. Young. Penelope Young and Quincy Sharp's plan to use the TITAN formula to reform criminals lead to Arkham Asylum being shut down. Creating the formula caught Joker's attention and instead of using it to rehabilitate the patients Joker decided to himself and other inmates into monsters.

Dr. Young's willingness to work for Joker who was helping to fund her with money to continue her work. Lead to events she that didn't expect and lead to Arkham Asylum being shutdown this allowed Hugo Strange and Quincy Sharp to carry out their secret plan to open Arkham City.


Dr. Penelope Young is determined and obsessed with her work, experimenting and researching constantly and even on holidays. She is cold and careless towards her coworkers and associates, but will become agitated if there is interference with her work. This obsessive dedication leads her to committing immoral and even criminal actions to further her research. However, she is shown to be noble in her goals of curing criminal insanity, and takes her job seriously. She is shown to be gullible as well, as she falls for the Joker's manipulation as Jack White and even is convinced by Jonathan Crane/Scarecrow that he is completely sane.

Aside from her work and studies Young doesn't seem to have to many things in her life that she enjoys or cares about. She puts all her focus and time in her work and project and nothing else. She is rarely is in a good mood. Despite her noble efforts to help her patients she is regardless of how she treats others especially how she treats her other employees. Because of her obsession and pride with her abilities, skills and work Young doesn't have a regular normal life like most of the other staff who work at the asylum. Dr. Young feels like she always has to stay busy and has to always be doing something.

Despite falling for Joker's manipulation as Jack White and Young believing Crane's lies about him being sane. Even though she is gullible enough to believe the two villains many blackgate prisoners and many of Joker's men mentioned Young's reaction seeing Joker back at the asylum made it seem like she knew what he was up to and what was going on. Many of them of Joker's men are clueless about Young working with their boss. Aside from Dr. Young not knowing that Joker is Jack White before she works at Arkham it is hinted that Young worked with White for awhile but never actually met him.

Young not only is clueless that Joker and Mr. White are the same people Penelope Young decides to make a deal with Joker when he asks her to do something for him in return when he threatens her. Fearing his threats Young agrees to do what Joker ask until his plan goes to far and gets out of control. Despite her fear of him Young is excited that Joker has shown interest in the titan project. Instead of questioning Joker and finding this suspicious about why he wants to be involved with the project Young is just pleased one of her patients has show interest in her plans.

Not only is it easy enough to convince Youmg that Johnathan Crane is sane rather then insane but Young mentions her notes she would like to see have seen how Joker's manipulation work when he manipulated Harley. Young describes herself always busy on holidays like Julian Day she also believes that he is one of the easier patients and lesser dangerous then the other inmates. All the other doctors would disagree with Young claiming that Crane is sane and that Julian is an easy patient to work with. Not only does Young say that Julian is calm and easy to work with but she mentions that she sees Julian as being free from societal norms.

Young often either pity's her patients or sometimes trusting or believing how they describe themselves to her even though they are lying. Not only does she feel bad, trust some of them but she also thinks some aren't as bad or dangerous as other doctors claim. One example of Young's view on her patients is her notes on Oswald Cobblepot she writes how she see most other people misunderstanding his intelligence. Although Young is naive enough to believe what her patients tell her she is clever enough to solve some of Edward's riddles he has sent to her daily and she is one of the few people to mention how she noticed his trophies and other clues spread out across the island.

Because of Riddler's intelligence Young mentions in her notes that she was thinking about having him assist her on the Titan Project when he is cured of some of his obsessions and disorders. Young believes after Titan changes Edward his high IQ can be helpful with her work if she can get him involved with her project. Aside from working with Joker and considering bringing Riddler on board with the project when he is reformed Young also also considered making a deal with Crane and letting him in on the project.

While Young has shown interest in bringing in more intelligent minds to help work on her project she mentions in her notes despite being impressed with Isley's high IQ. Young doesn't like how Isley views and sees most humans as bad Young dislikes Isley's hate for humans and how she doesn't care for them. Aside from her disgust of Pamela's treatment of human Young also mentions how she dislikes Pamela's treatment of males as well. Despite not liking Isley's hate for humans Young is impress with Isley's research on plants and how she wants to use that research in her Titan Project. Young writes in her notes that she doesn't like Isley's hypersensitivity and how she believes all men are in love with her so also has distant for Isley's hate for men and how she uses them for her own purpose and gain.

Young wants to use Isley's research in her project but has no interest in bringing or using Isley's IQ in her project. Young wants to use Isley's research and mutanted plants with out Isley's permission and without out her involvement. While being impressed with Isley's research, Bane's venom and Edward's riddles Dr. Young is also interested and intrigued with Crane's fear toxic. While Young admires the IQ of some of her patients and disproves of Pamela's hate for all humans Penelope Young also dislikes Edward's view point of how he thinks of other people as stupid.

Even though Young is cold, heartless and careless to her other workers she is shocked how cold Pamela is to all humans and how Edward considers everyone as ignorant. She dislikes Edward saying that if people were smarter his puzzles and riddles wouldn't be death traps if people were smart enough to escape, smart enough to not get kidnapped and smart enough to survive.

While Young talks to her patients and questions them about their obsession with Batman. She is curious about Riddler's obsession with riddles, Ivy's obsession with plants, Two-Faces's obsession with his coin, Scarecrow's obsession with fear, Firefly's obsession with fire and Calendar Man's obsession with holidays. Young often questions them about their obsessions however Young doesn't like her patients or other people questioning her. In a few of her interviews when Joker and Riddler question her Young gets annoyed by them. While Penelope Young doesn't like other people questioning her in her notes Young writes that she really doesn't like Clayface mimicking, impressioning or copying her.

Her interaction with Clayface in her notes shows that Young doesn't like being, questioned, mocked or insulted. Young denys that Clayface's impressions of her her being bitter, sour and cold are true Young belives that he is wrong about her. Aside from Clayface Young dislikes other employees mention about het being bitter, miserable, strict and to serious. Young is very determined when her mind is set on something there's no changing and stopping her. Young gives orders but doesn't like being told what to do.

She is someone who takes pride in her control over other and telling them what to do Ms. Young is so a woman who is full of herself. Aside from pride in her work she has pride in herself despite being gullible, foolish and naive to be tricked by a few of the inmates Young is very confident and has an ego. Most of her actions even noble acts to help cure the villains for a good cause are mostly done for own her self intrest to make an even bigger name for herself.

Despite her noble goal to cure the patients at Arkham Asylum Doctor Young has sometimes referred to the criminals and other villains as specimens instead of patients. Although Young wants reform the inmates of Arkham into normal citizens to Ms. Young they are nothing more then just test subjects this is seen when she refers to them as specimens.

In her notes Dr. Young writes that she has noticed trophies, clues and other clues all across the asylum grounds. Despite being impressed with his riddles and intelligence Young mentions in one of her interviews that Edward would be a good candidate for the TITAN process.

Dr. Young mentions in one of her interviews the doctors have an endless of disorders they believe he suffers from but nothing matches or fits with the Joker's actions.

Joker tells Dr. Young if she wants to know the truth or know more if she scratches his back getting him what he wants and he won't have her killed for asking so many questions and for her curiosity.

While Dr. Young is intrigued with figuring out what makes the Joker who he is and aside from scratching his back to get him what he wants. Ms. Young is impressed with Joker showing interest in Project TITAN and how he wants to help assist her with the project. Before her amazement that Joker wants help her with the program Young is at first suprised with him knowing about the project before she agrees to work with him.

Dr. Young's Notes on Harley Quinn

There are no interview tapes with Dr. Young and Harleen Quinzel aka Harley Quinn. Dr. Young mentions because of Harleen's fall from grace Young and many other doctors had to go through psychological screening, training and testing to make sure no more doctors become easily manipulated like Harley.

She writes in her notes that she preposterous of them thinking that herself or another doctor could be easily manipulated.

Dr. Young's Notes on Bane

Bane is one of the inmates that Dr. Young has notes on but no interview tapes with him. Ms. Young mentions in her notes how she is intrigued how the vemon enhances many of his abilities.

Aside from Young being upset with how Isley's hate for humans Dr. Young also doesn't like Isley's treatment and view point on males like as if all males are bad. Despite Dr. Young mentions how she doesn't like how Ivy treats humans she finds Isley's research on plants fascinating. Much like Bane's venom Young wants to study about Isley's chemicals she uses for her plants. She wishes to harness and use both Bane's venom and the substances from Ivy's plants.

Dr. Young's Notes on Calendar Man

Young has no interview tapes with Julion Day aka Calendar Man aside from that Dr. Young has learned more about Julion then any other doctor. This is because since Dr. Young likes to work with little free time and hardly any breaks Young does not believing in taking holidays off from work. Because Penelope Young likes to work on holidays and Julion Day is active and commits crime on holidays Dr. Young has been able to study and learn more about Julion.

Despite Ms. Young knowing Julion better then most other doctors she has learned Julion becomes more impossible, dangerous and difficult to deal with when the holidays come around. in her notes Dr. Young mentions it's hard to get Julion to socialize which is why it's hard for other doctors to learn anything about him.
