💜🃏Jeremiah Valeska Headcanons 🔪💣 (ft. Jerome):
1. Before he was abused and before Jeremiah left, Jerome was a normal kid. He took risks, loved jokes, and enjoyed pulling pranks, but he wasn’t “crazy.” Jeremiah, on the other hand, was considered a very strange kid. Because Jerome was wild, Jeremiah liked to act as though he was the “sane” twin. In reality, Jeremiah would do or say a lot of weird things that didn’t make sense to anyone but himself.
2. He’s a compulsive liar and often makes up a lot of things about himself (which only slightly got better as he grew up).
3. He has an eery and unnatural fearlessness (though he tries not to be too reckless) and would often have to fake his fear in order to seem more normal in the eyes of others. He also has a freakishly high pain tolerance, which would often secretly baffle Jerome as a kid.
4. As a kid, one of Jeremiah’s favorite hobbies was dissecting stray animals (mostly alley cats) out of “curiosity” and then blaming it on Jerome (in the future, after killing his mother, Jerome’s memories blurred together and he genuinely believed he was the one responsible for all the dead animals when he was a kid).
5. He’s always had odd responses and reactions (such as the time his mother freaked out over a spider and Jeremiah’s immediate reaction was to hide it instead of getting rid of it).
6. One strange tendency he’s always had, which always embarrassed him as a kid, was letting out random, short bursts of laughter or giggling (which he learned to control as he grew older).
7. Ever since he was a kid, he’s had a habit of arguing with himself, out loud, when he’s trying to make a decision (this would earn him a lot of weird looks from the other circus folk).
8. After leaving the circus, he was bullied in school for being “weird”, causing him to attempt to suppress his strange behaviors. All his progress came undone after being sprayed by Jerome’s insanity gas.
9. After being sprayed with the insanity gas he started hearing multiple voices in his head, three of them being Jerome, Lila, and Zack.
10. He’s really good with makeup and often tried on Lila’s makeup as a kid, which Jerome secretly knew about.
11. He’s an extreme pyromaniac and secretly loved setting things on fire when he was a kid, once almost setting the trailer on fire (y’know, for science). His obsession with fire, however, eventually evolved into an obsession with bombs and explosions.
12. After being sprayed with the insanity gas, he adopted two pet hyenas for Ecco on her birthday (one is named Bruce while the other is named Lila). After killing Ecco, Jeremiah took care of the hyenas until they were later given to Harley Quinn.
13. Similar to his mother, he has a slight addiction to alcohol and usually drinks whenever he’s stressed/paranoid, sad, or disappointed.
14. He’s always loved a good show and was definitely interested in theater. However, I think he refused to indulge in those interests/desires in fear they’d make him seem similar to Jerome.
15. While sleeping, post-spray!Jeremiah sometimes speaks complete nonsense, says incredibly disturbing things, or just giggles (I feel like Ecco would somehow know about this and record him without telling him).
16. While Jerome’s canon favorite ice cream flavor is chunky monkey, Jeremiah’s favorite ice cream flavor is mint chocolate chip (I also like to headcanon that Jerome would make fun of him for liking ice cream that, in his opinion, tastes like toothpaste).
17. After being adopted, he was diagnosed with general anxiety disorder, insomnia, and OCD. After being sprayed with the insanity gas, he developed psychosis and depersonalization disorder.
18. He’s definitely a cat person, which he probably tries to hide. He’s the type of person to be strongly against getting a cat but ends up being the one most attached to it/also probably hates dogs, especially big ones. However, he still has no qualms with killing cats as long as they’re feral.
19. He’s agender (AMAB) and goes by any pronouns (I think, especially after being sprayed with the insanity gas, he’d be completely apathetic to the concept of gender and just wouldn’t care).
20. He’s bisexual with no preference (pre-spray!Jeremiah had a crush on Ecco and post-spray!Jeremiah developed a crush on Bruce).
21. He once sent a chocolate cake to the Wayne mansion on Bruce’s birthday and said it was from Gordon, but when Alfred cut into it it was just lasagna shaped like a cake and covered in chocolate frosting.
22. Due to years of drawing out his plans for engineering and designing mazes, he’s actually pretty good at drawing and enjoys sketching weird things when he has nothing else to do (which is rare as the Joker).
23. I feel like he’d be really into 1920s jazz music and electric-swing and would dance to it with Ecco (I headcanon his favorite song to be Let’s Misbehave by Irving Aaronson).
24. He never actually needed glasses, he just wore them to look “smarter” and to differentiate himself from Jerome.
25. I feel like his adoptive parents would’ve made him learn an instrument (specifically piano) throughout middle school and high school (probably far-fetched).
26. Puns make him unnaturally and unreasonably angry, so of course Jerome would make them all the time when they were kids (he considers puns to be an insult to actual jokes). He also probably fell for a lot of Deez Nuts jokes, courtesy of, surprisingly, Ecco.
27. Jeremiah = Mad Hatter
28. His and Jerome’s birthday is April 1 (April Fool’s Day).
29. He’s extremely unpredictable after being sprayed with the insanity gas, which adds to his chaotic behavior. Some days he’ll commit crimes such as murder or blowing up a hospital, other days he’ll pull weird, elaborate pranks (usually on the GCPD or Bruce/Batman).
30. He’s the only one besides Alfred who knows that Bruce is Batman.
31. Really bad at and hates video games (except The Sims/probably made a Sim of himself and Bruce).
32. (⚠️Trigger Warning⚠️) Was probably sexually abused by his uncle without Jerome’s knowledge (otherwise Jerome would’ve killed Zack a lot sooner) and was a big part of the reason why he lied in order to leave.
33. I can see him being interested in learning different languages to expand his knowledge, mainly Spanish, French, Russian, and German.
34. Definitely born the younger twin, but became the older twin after Jerome died for a year and thus stopped aging.
35. For some reason I feel like he’d really like horses and would probably show up at Bruce’s mansion with a black horse wearing a tutu and a clown wig as a present or something.
36. Ecco sometimes catches him talking to animals or inanimate objects like he’s having an actual two-way conversation.
37. He learned how to wield a knife and use basic hand-to-hand combat from Ecco. However, he mostly relies on tricks to beat an opponent.
38. If he were an animal he’d be a purple poison dart frog (or a peacock lmao). Jerome would obviously be a hyena and Ecco would be a cat (guess what Bruce would be).
39. Constantly tells jokes and pulls pranks in a desperate attempt to make Bruce/Batman laugh (which of course only Harley manages to accomplish).
40. All of his weapons are custom made and have a clown/circus theme. He also has fake guns that just shoot out red flags saying “BANG!”
41. He hates bad manners/etiquette and tries to seem as proper as he can while at the same time acting like a clown. He’s a weird mix between polite and psychopath.
42. Absolutely despises being or getting dirty. Even just the thought of being covered in any form of filth makes his skin crawl.
43. I genuinely think that the only thing the insanity gas did to him was amplify his already existing thoughts and behavior and take away all of his impulse control.
44. As a kid he would manipulate Jerome into doing whatever he wanted, which mainly consisted of stealing things for him (I firmly believe Jerome was stealing Zack’s snickerdoodle cookies for Jeremiah).
45. Besides changing color (after the gas), Jeremiah’s eyes can also see extremely well in the dark.
46. If I were to give him a theme song it’d probably be Mama’s Gun by Glass Animals. I just think it fits the whole going insane vibe.
47. Jerome is against killing or hurting babies and children, but Jeremiah won’t hesitate to get rid of anything in his way (except Bruce).
48. Refuses to swear and instead says the weirdest things as a substitute (Ecco tries so hard to deal with it).
49. Actually likes snakes and got along well with them like his mother. He was definitely Sheba’s favorite and was the only one she tolerated besides Lila.
Note: I’ll probably add onto this if I think of any more. Also, feel free to let me know what you think.
