family of figures

You live with your family and everyone has their own figure: Mom has a star, Dad has a triangle, the younger sister has a hexagon, the older sister has a square, the younger brother had a rhombus and you had a circle which you were so used to that you never gave it to anyone, but after a while, a very rich family brought in an adopted brother to whom they gave your circle without permission, and instead of a circle, you had a pentagon
and each figure had its own power and value. For example, a circle could make a transparent barrier, a pentagon could shoot a web like Spider-Man, etc.
and Mom loved everyone very much and secretly she could have a heart attack if someone was rude to her and left the family. This had already happened with the older brother, who had the figure of a cross, he was very smart
and you stood in the hallway asking why they gave him your circle
