Bad guys from DBZ.
Even before Piccolo shows his bad side to battle Kakarott, he saves a little boy and his mother from being killed by a stone that broke out of a church wall through a lightening. It shows how deep Piccolos yearning for an own family is because the moment he was born, he was alone. He never had parents. Every child he sees reminds him of himself. His childhood was only filled with heartache and sadness. He could never kill a child. He could never kill himself.
