Colonel Hyrum Graff
Colonel Hyrum Graff is director of the Battle School where soldiers and commanders are trained for the I. F. (International Fleet), the starship force for the military on Earth. Graff takes personal charge of training Ender, understanding intimately how to motivate him and turn him into the commander they need. His strategy is to isolate the boy and create opposition around him so he will learn problem solving. Though Graff personally loves Ender, he never lets it show, having to be merciless on him. Graff tries to break down the spirits of the children in his charge, taking them to the edge, in order to make the toughest soldiers. He allows the dangerous situation to develop between Bonzo and Ender, leading to Bonzo’s death. Graff always covers up for Ender when he injures someone else. He is put on trial for negligence in Bonzo’s death after the bugger wars, but he is acquitted because the court cannot prove that Ender would have become just as good a commander without the violence of his training.

Andrew (Ender) Wiggin
Ender is called a Third because families are only allowed to have two children. The government has given the Wiggins a waiver to have a third child, hoping he will be the genius military commander they are waiting for.
Ender knows the Battle School is trying to make him into a murderer, which is contrary to his nature. His greatest fear is to be like his brother, Peter. Valentine is the person he loves most in the world, and he is motivated to be a soldier to save her from the buggers. Ender is a great creative problem-solver, coming up with new solutions in battle situations. He knows how to bring a group together. His troops are loyal to him, and he wins the bugger war at the age of eleven.
The adults training him secretly love him but know they have to trick Ender into committing violence against others. Ender is superior not only in intelligence but also in moral perception. He may defend himself fiercely in personal combat, but he has a sense of fairness. He can understand other points of view besides his own; in fact, he wins because he can probe the enemy mind empathetically. After the wars, however, Ender is racked with guilt at causing mass deaths. He founds a religion based on being a Speaker for the Dead, preserving the culture and memory of the buggers, or for anyone else. Ender becomes a just governor of the new colony established on the empty bugger worlds.
Peter Wiggin (“Locke”)
Peter is the eldest child in the Wiggin family. Though a genius, he is passed over for military training because of his violence. His ruthless tactics are evidenced in the way he treats his brother and sister. He tries to hurt or kill Ender, and he eventually controls Valentine and gets her help in preparing world opinion on the nets for his own ascendance to power. He takes the pseudonym “Locke” pretending to be rational and liberal in his ideas when actually he is a dictator at heart. He wants to control Ender after the war, but Valentine makes sure Ender is out of his reach. In his old age, he asks Ender to be a Speaker for him, and Ender writes the book, The Hegemon, explaining Peter’s life.
Valentine Wiggin (“Demosthenes”)
Valentine is the second child and only daughter of the Wiggin family. Like Peter, she is considered for military commander because she is a genius, but she is rejected because of her sympathy and ability to be swayed. This is illustrated in the fact that initially she is the champion of Ender, and after he goes to Battle School, she becomes the partner of Peter, even though she does not like or trust him. Valentine is key to Ender’s development, for she is the only human he truly loves and who understands him. She twice has to intervene to keep him on his course in military training. Graff uses her to keep Ender in line. Valentine’s particular gift is her persuasive writing, and so she is given the character of Demosthenes by Peter to sway public opinion in an emotional, patriotic, and conservative opposition to the Russian plans for war. After the Third Invasion, she rescues Ender from Eros and takes him to the bugger worlds that are being colonized. She becomes a historian as she travels with her brother.
Ender’s father comes from an old-fashioned Polish Catholic family with many children and was persecuted as a child for it, since large families and religion are outlawed. He changes his name and officially renounces his religion to fit in, but secretly he is still religious and baptizes his children. Mr. Wiggin is not as intelligent as the mother. He believes in the conservative opinions of “Demosthenes,” not knowing the columns are written by his daughter. He truly loves Ender and is sad at parting from him.
Mrs. Wiggin is a Mormon and still secretly follows her religion. Ender remembers her praying over him when he was little. Graff convinces Ender to leave his family because he represents a hardship for them as a Third. The children credit Mrs. Wiggin for giving them their intelligence.
