Val was made by a creator specifically to be the child of Error and Ink. To respect the wishes of that creator, Ink decided to take her in and raise her as his own in the Doodle Sphere, alongside her older sibling, Pixel.
Val has powers similar to Error's, she has black/brown strings identical to Error's blue ones. She didn't inherit any of his glitching.
Val likes to fight. Training is one of her favourite activities. Her strings and giant needle are her main weapon.
Val's giant needle was a gift from Ink. She came up with the idea and Ink created it for her.
Val tried out and mastered several art forms over the years, painting, writing, dancing, playing instruments… She got bored of all of them eventually. She hates being bored.
Val isn't interested in her parents' creation vs destruction thing, but she finds the alternative universes very entertaining.
Val technically isn't a "Sans", so she doesn't have any Sans-like attacks like bones or Gaster blasters.
Val has a normal soul and feelings.
As the daughter of two immortal/semi-immortal beings, Val is also semi-immortal. She can die, but she can't die of old age.
Val doesn't need to eat or sleep to stay alive, but she is able to feel appetite and tiredness.
Val has the ability to eat paint (one of the few things she inherited from Ink). She tried eating it once and disliked the flavour. Never again.
Val's favourite food is Neapolitan ice cream.
Val has a CMYK color palette.
Val is a demigirl. She goes by She/Her pronouns.
Val is left handed.
Besides English, Val can also speak Spanish (like her original creator).
Error didn't like them too much at first, but nowadays he has a good relationship with both Pixel and Val. They visit the Antivoid and watch Undernovela with him sometimes.
Ink spent years raising Pixel and Val, teaching them everything he knew and taking care of them to the best of his capabilities. Nowadays he doesn't spend much time with them, but he still loves them all the same. When he remembers them.
The Doodle Sphere is still their home, but they don't actually spend much time there. Once they mastered the creation of portals, Pixel and Val started to travel the multiverse together.
Val likes to try out different foods and collect trinkets and reminders of the AUs she visits.
