Heroes who are brothers or sisters of the other characters, including other heroes (they can also have villainous siblings, too) - this category can also include half-siblings, step-siblings as well as adoptive siblings.

Some siblings are more protective of each other than their own parents, especially if those parents are villains or abusers.

Some siblings have a terrible rivarly and barely get along at all, and some heroic siblings are enemies to their villainous siblings. Sibling bonds and relationships work differently, and some of them love each other very much, regardless if they get along well or not. Good-hearted siblings are eager to lend a hand and look out for one another, and never fight physcally.

For example: Anna and Elsa are full blood related siblings, Cinderella and Anastasia are step-siblings, Yuji Itadori and Choso are half-siblings.
