Mazer Rackham

Mazer Rackham was the hero of the second bugger invasion, he is also Ender's teacher. This should be impossible, because the second invasion happened 100 years before, but it's not. Mazer Rackham was put into a ship and sent into space going at a relative speed. By doing this Mazer Rackham is only 8 years older then from the end of the second invasion. Mazer was sent into space to stay alive in order to teach Ender. Mazer is similar to Ender he is always very serious and has a brilliant mind. Mazer understands the buggers better then everyone else. Mazer realizes the connection between the Queen and worker buggers. With Mazer's training Ender is ready to fight the buggers and to lead the humans to victory.
