Headcanons if Tom Dupain Was Related to Oswald Cobblepot

Summary:

Because I love Maribat and idk why but this made me have an idea of Mari being related to a villain from Gotham. But these are headcanons of her being related to our favorite mobster.

Notes:

Also the Oswald I prefer is from the Gotham show in Fox.

Chapter Text

  • Tom is Ozzy’s half brother, who is older than our favorite mobster
  • Gina, a week before marrying Rolland, went to Gotham and met Ozzy’s father and had a one night stand with him not knowing he was wealthy (WHY CAN’T OZZY HAVE LIVING PARENTS???)
  • After they married Gina and Rolland were surprised that she was preggers
  • Rolland was happy believing it was his kid
  • But Gina knew it was from the guy from Gotham
  • Because why would Tom be like…6 feet tall when Rolland is like…4 feet something tall???
  • But Rolland doesn’t notice
  • Of course, Gina writes to Elijah but never reads any letters written to her back
  • Once Gina and Rolland divorce she comes clean to Tom about who his actual father is
  • Tom doesn’t mind but after his 18th or 20th birthday he changes his last name to Van Dahl to distance himself from Rolland
  • Once marrying Sabine they notice a very pale man wearing a suit with black hair, pointy nose, and cane alongside a bald man who wore all black at the church
  • Turns out once Ozzy’s mom died bc of Tabitha Galavan and met with Elijah he found the letters hidden somewhere in the mansion before Elijah died
  • He was shocked but not angry of course
  • He kept tabs on his half brother
  • When he heard that Tom was to marry his College/University (???) sweetheart he and Victor (Zsasz) flew over to see them marry
  • During their reception Ozzy tells the newlyweds who he is
  • Tom is shocked
  • Even more so when realizing his half brother is a criminal but decides that it’s fine as long as Oswald doesn’t hurt those close to him
  • To which Oswald agrees unless they hurt Tom and his now half-sister-in-law
  • He comes back every now and then to visit
  • When Marinette is born, her name is Marinette Van Dahl-Cheng
  • Oswald was there with Eddy
  • “What do you mean you don’t want to change your last name to Cobblepot? Her last name could be Cobblepot-Cheng! Much more….easy to go by.”
  • “Eddy dear you aren’t helping.”
  • “But…Marinette Cobblepot-Cheng…ah! Yes, doesn’t have the right ring to it.”
  • Of course, the only ones to know about Tom and his fam is Eddy, Zsasz, and Jim Gordon (probably Fish Mooney but idk yet)
  • Marinette grows up with odd visits from Oswald who spoils her at times and learns a bit of English from him
  • She likes to show off her designs to him which he gushes about
  • When she receives her miraculous she’s excited
  • Also finds it ironic how she’ll have to be a hero when her half uncle is a villain
  • She makes his suits as well as Edward’s
  • Whenever Oswald visits he tries to not bring attention to himself and just hangs with the family
  • He sometimes brings Ivy with him who gushes about the sweets and Mari’s designs
  • He likes to tell Mari stories about Gertrud and how she raised Oswald
  • Mostly tells Mari stories of her half grandmother
  • Surprisingly, Mari knows more about her half grandmother than her actual one
  • Chloe and Mari are friends in this au bc I say so
  • Though Chloe’s dad did find out by googling Mari’s last name out of curiosity
  • Mari’s hair is like Season 1 Ozzy’s if she has a somewhat bad hair day
  • Although, she does make herself have a pixie cut with a mowhawk as Ladybug
