jaina is the daughter of pro hero fat gum, her quirk is crystals. she can manipulate her blood sugar into forming purple pink crystals to create a shield or across her arms. People assume that since Fat Gum is a homebody pro hero, they would the same for him being a dad, but that is not the truth. He’s often very dismissive towards Jaina unless they are combating with her quirk. He can be cruel in a way that’s not regular training.
