Bean
Bean was a friend of Ender when Ender joined the Dragon Army he was a little younger then Ender also ,"Even though there are some better soldiers than you in Dragon Army-not many but some- there's nobody who can think better and faster than you." (Page 198) This problably meant alot to Bean and problably inspired him in battle.
Ender Would also think about Bean. Bean was a really skilled companion especially in battle. "But I'll be watching you, more than compassionately than you know, and when the time is right you'll find that I'm your friend, and you are the soldier you want to be" (Page 168) This means Bean really had the potential to be a really strong and skilled soldier since Ender is watching him and telling him hes watching him. Bean could even be strong as Ender, but this also meant Bean and Ender were good friends.
Bean once walked into a room where ender was and told him he was transfered to The Rabbit army. Ender then asked "Well, whos commanding Rabbit Army then? Bean held up his hands helplessly. "Me." (Page 221) Ender was problably dissapointed in the people taking Bean away from him and Bean was peoblably ashamed. Also but Bean must be really strong and have great potential to command his own army.
