Graff reassigns Ender to Salamander Army, led by Commander Bonzo Madrid, a short, bitter, but intimidating squad leader. Ender quickly adapts to the games, devising new strategies older students have not yet seen. Among other studies, the cadets are placed in squads and perform training games in a zero gravity 'Battle Room'.

Graff brings Ender to Battle School, an orbiting space station in Earth's orbit, placing Ender with other cadets his age, but treats him as extraordinary, ostracizing him from the others. That evening while the family is having dinner, Graff arrives to reveal he was being tested and is still part of the program. Ender confesses his grief to his older sister Valentine, but is harassed further by their older brother Peter. Ender is attacked by Stilson, a bully student he defeated in the combat sim, but Ender fights back and severely injures him. They order the removal of his monitor, signifying the end of the cadet program. 12-year-old Cadet Andrew 'Ender' Wiggin (Asa Butterfield) draws the attention of Colonel Hyrum Graff (Harrison Ford) and Major Gwen Anderson (Viola Davis) by his aptitude in simulated space combat. Over the course of 50 years, gifted children are trained by the International Fleet to become commanders of a new fleet for this counter-attack. In the near future, humanity is preparing to launch an attack on the homeworld of an alien race called the Formics who had attacked Earth and killed millions the Formic invasion was stopped by Mazer Rackham, who crashed his F-35 Lightning II into a Formic queen ship at the apparent cost of his life. But at what cost, and to whom? - BlueEyes001 This ability is seen by those old men solidified in their ways, who have no flexibility in their thinking anymore, and exploit Ender to achieve their own ends. He is gifted with the ability to become his aggressor and think like his aggressor thus giving him the key to the aggressor as he learns to love them through their frailty - using this to exploit them and thus destroy them. Having been brought in to being by loving parents who gained permission for his birth, Ender feels he is not only unwanted but excess baggage to the world. Ender is a third child in a population overloaded world that is reeling from the previous war with the alien race of insectivorous beings who work and behave like the ants nest, the Formics. His sister the kind and compassionate one sees only through an affected sense of contact.

His brother, the brute jock, is violent and only sees through strength and brutality. Ender is a slight fragile teenager with the expanding mind of a genius.
