Personality
Before he gained immeasurable strength, Aomine was out-going and even friendly. He often fooled around with Kuroko or Kise. Momoi stated that the old Aomine was so alike with Kagami. He loved playing basketball and was very good at it too. But he kept training and he kept getting stronger, to the point that he totally crushed his opponents' will to play basketball. He was initially sad about this, and searched for his equal on the court, but he never found one.Eventually, he came to conclusion that he is simply the strongest and that "The only one who can beat me, is me". He also cast his feelings towards his opponents aside and now views them as weak and wants to crush them. He seeks to humiliate them in the worst kind of fashion. He has also become very lazy, only coming to training when he wants to, and slacking off even during matches, sometimes abusing his teamates in the process.
Aomine also has a short temper and some kind of admiration towards Kuroko, as he threatened a Tōō player with physical violence when he spoke badly about Kuroko. Also, when Haizaki stole food from Kuroko, Aomine told him to get his own food. Another trait he shows, is that he is a big fan of Japanese idols. He is interested in that field of entertainment and knows a lot of idols and keep them apart well. He has said he likes models with big boobs.
Aomine is shown to be very protective of his former teammates in Teikō Junior High. Something his current teammates in Tōō Academy refer to as Aomine's "soft side". This was shown when Aomine attacked one of his teammates in Tōō after he badmouthed Kuroko's style of play. After Kise's match against Shōgo Haizaki ended, Aomine conforted Haizaki in order to make sure he does not attack Kise later on or get in the way of Kise's and Kuroko's match at the Winter Cup.
