Ike has little memory of his life in Gallia as a young child, and prior to joining the Greil Mercenaries, expresses an ignorance towards the existence of the Laguz race. This has had a positive effect on Ike's character, as he is portrayed to bear no prejudice against the Laguz race, whereupon he winds up gaining their trust with his actions, one of which include defending Ranulf from being assaulted by a group of Beorc.
Ike is rather naïve when he is introduced, often taking things at face value. He is characterized by a kind and brave personality, and is very protective of his friends and family.
Despite having played a major role in liberating Crimea from Daein, Ike is shown to be rather humble, and seeks no reward for his actions, save for the fees he charges as a mercenary. By the end of the story, he has realized his role as a mercenary in Tellius is over, and leaves for lands unknown.
