Now, here are some headcanons for Girlfriend, Daddy Dearest, and Mommy Mearest.

1. Girlfriend's real name is Cherina Melody Dearest, or just "Cherry" for short. Her parents sometimes call her "Daughter Dearest" as an affectionate nickname.

2. Daddy Dearest's real name is Luis, while Mommy Mearest's real name is Roxanne.

3. Girlfriend is a succubus. Succubi are types of demons who feed off of love, so that pretty much explains why Girlfriend is so attached to Boyfriend. That being said, Mom is also part succubus (for obvious reasons). Dad is probably some other type of demon, maybe a devil or something.

4. In contrast to her husband, Mom actually supports Boyfriend and Girlfriend in a relationship. She thinks it's great that her daughter is feeding off of love like a real succubus and hopes that one day, she will use that love to grow more powerful.

5. The reason Dad challenged BF to a rap battle for his daughter's love was because he was also tested in a similar manner when he was engaged to his wife, as Mom's own father tested him when he was young (and before he became a rockstar before retirement).

6. The Dearests come from a Hell-like place, which is fitting since they are demons. They ascended to Earth to pursue their musical careers, and now live in a big, fancy mansion with demon servants.

7. Demons age differently compared to humans, as they age up until a certain point. Dad and Mom might actually be older than they look, and despite being nineteen in human years, Girlfriend is actually pretty young for a demon.

8. After retiring from his rockstar career, Dad fell out of singing for a while. This is why his week was relatively easy compared to the other weeks (then again, it is the first one).

9. Demons can be created in different ways. They're either born naturally like humans are (in Girlfriend's case) or artificially created (the background dancers/henchmen in Week 4). The reason Mom has those henchmen is because she and Dad are pretty rich because of their former jobs, and they have the technology to create those funny guys. She doesn't mind them in the slightest...but they're easily disposable (and quite stupid), so there's not much she can do about them getting killed other than making more of them. The henchmen themselves might be stupid, but they're loyal to Girlfriend and her parents. But Girlfriend doesn't really need a bodyguard around her (unless Dad hires someone else to keep her in check) other than her boyfriend.

10. Dad is overprotective of his daughter. This nature stems from the fact that they're demons, so they're naturally seen as evil, mindless creatures. Girlfriend almost got killed by a human when she was pretty young, so Dad dreaded something like that happening to his family ever since. But he is seen as the bad guy, likely due to him trying to kill Boyfriend, which led to him becoming just as bad as how people viewed demons.

11. It was Mom's idea to take over the mall so she and Dad could have another match against Boyfriend in Week 5, while it was Dad's idea to hold the mall Santa hostage so they could use his chair.

12. Neither Dad nor Mom had the Lemon Monster involved as part of their plan in Week 2 or Week 5. He just randomly appeared out of nowhere, and they probably don't know who he is.

13. Dad and Mom have human disguises just like their daughter, but they just don't care to use them. When they do use their human disguises, they often wear more modest outfits with them.

14. When Dad and Mom first met Skid and Pump, they thought Pump's eyes were naturally a blue color.

15. Dad is extremely petty and holds a lot of grudges.

16. Most of Dad's shirts either have incredibly low necklines or are buttoned in such a way to expose his chest hair.

17. Dad's jacket has multiple pockets lining the insides for various items, including his phone, gun, and microphone.

18. Dad dislikes the taste of cherries.

19. Unlike her husband, Mom easily warms up to Boyfriend because she can appreciate his musical talent and his resolve is by far the most she's seen out of any of her daughter's previous boyfriends.

20. Mom's favorite drink is black cherry White Claw.

21. Mom is friends with Skid's mother, Lila.

22. Mom has the ability to control people. She can only do it to one person at a time, and it's less like possession and more like deep hypnosis.

23. When Girlfriend started dating Boyfriend, she used her demon powers to grant him the ability to regenerate himself. This ability would be very useful for rap battles with opponents. Since he is able to regenerate, Boyfriend is unbeatable and can take down his opponents in rap battles with ease.

24. Girlfriend isn't really scared of the Lemon Monster because she spent most of her childhood in that Hell-like place of hers. However, her fear of lightning was just some sort of instinct kicking in.

25. Girlfriend babysits Skid and Pump on weekends as a way of making extra money.

26. Girlfriend has a driver's license and likes going for drives late at night. She loves the aesthetic of the streetlamps on the dark road.

27. Girlfriend played volleyball in high school, so she can kill a man with a single slap.

28. Girlfriend doesn't sing or rap as often as her parents or boyfriend, but when she does, she has a very beautiful contralto voice.

29. Girlfriend learned Latin in high school, and is still fluent in it. She even calls Boyfriend Latin pet names sometimes, such as "mihi amata" (my love) or "mei cara" (mine dearest).

30. Girlfriend's favorite food is pumpkin pie and her favorite drink is tea. (Cherry Dr. Pepper is her second favorite drink)

31. Girlfriend likes to sing karaoke.

32. Girlfriend's favorite board game is Monopoly, and she always crushes Boyfriend and Pico whenever they play it with her.

33. Girlfriend is skilled at many different musical instruments. She can play the violin, piano, cello, and flute.

34. Girlfriend likes to paint her fingernails. She usually keeps them red, but sometimes she'll shake it up and paint them black or pink instead.

35. Girlfriend is very fashionable, and likes to go shopping for clothes. Her signature outfit is her red dress, and she has a closet full of them. There are at least ten dresses of the same color in that closet. When she isn't wearing a red dress and heels, she likes to wear sweatpants or jeans, long sleeved shirts, and sneakers.

36. When Boyfriend first met Girlfriend, she didn't tell him that she was a demon until she fully gained his trust. She showed him her horns, glowing red eyes, and purple skin, and surprisingly, instead of getting freaked out, Boyfriend actually took it pretty well. When Girlfriend showed him her demon form, he responded with a simple "Whoa, that's pretty sick." Girlfriend is very happy that Boyfriend doesn't worry about her demon heritage.

37. Girlfriend's favorite music genres are rock and pop. Having an ex-rockstar and pop star as parents probably had something to do with it.

38. Girlfriend's favorite video game franchises are Pokemon and Animal Crossing.

39. Girlfriend always wears perfume that makes her smell like jasmine or roses.

40. Girlfriend is a great artist and likes to make paintings and prints that she often sells on Etsy.

41. Girlfriend really loves Cherry Dr. Pepper. Whenever a friend buys her one, her eyes will sparkle that demonic red color.

42. Girlfriend likes using cheat codes when playing games, but doesn't like cheating in relationships.

43. Girlfriend's favorite game is Tetris. She also likes strategy games and puzzle games in general, like spot the difference, hidden object games, crosswords, etc. She thinks they're pretty relaxing and fun.

44. Girlfriend's speakers are foldable and have wheels on the bottom, which is how she is able to bring them with her everywhere she goes.
