Personality

Jonathan displays an obsession with Lewis Carroll's Alice in Wonderland, but is also quite well versed in pop culture; using his ability to mimic voices to cheer up Beth, by references films like The Goonies (1985), by quoting how, "Goonies never say die!" [15] and then he also uses his mimicry to sound like Emma Watson as Hermione Granger in the scene from the 2001 film Harry Potter and the Philosopher's Stone, when she tells Ron he's saying it wrong and that, "it's Leviosa, not Leviosar".[16] He is also prone to jealousy to the point where he will kill an innocent person, because Alice is more focused on someone else. He has shown to be more connected to reality than Alice is, as unlike her, he knows for certain that Kate would never join their little family.

The only positive trait that Jonathan has is his undying love and loyalty towards Beth. He sees her as his one true family for she accepted him and loved him despite his horrendous appearance and was more than willing to protect her from his father's wrath.

Appearances

Batwoman


Behind the scenes

  • Johnny is the first case of gender-bending in Batwoman since he's based on the villain Jane Cartwright aka Jane Doe, who first appeared in the Gotham episode "Nothing's Shocking". She was a serial killer and an Arkham Asylum patient, who was under the psychological delusion that her face was hideously disfigured and wore a mask at all times. She had the ability to shape-shift into other people by touching their skin.
    • She was a composite character and based on two different Batman villains: Jane Doe, a master of disguise with the power of mimicry, and Calendar Girl; a supermodel deluded into thinking she was ugly that wore a similar mask.
    • The comics version of Jane Doe is mentioned by Bruce Wayne of Earth-99 as an Arkham inmate.
    • Johnny is also the third case of gender-bending in the Arrowverse where a female character was changed into a man. The first two were Lucious Coolidge and Heatstroke, making Johnny the first who isn't a fire-based villain.
