He is voiced by Cindy Robinson.
Ewan is a short blond boy with gray eyes. He wears black suspenders with plaid maroon-purple shorts with a pocket on each side. He also wears a grey shirt with a red tie, white socks, and black shoes. According to Nene, his eyes are very similar to Mikey's.
One year later, Ewan is quite a bit taller, and usually wears a yellow button-up shirt with white pants, and gray and green sneakers with white soles.
Like Mikey, Ewan is an excellent strategist, able to come up with good battle actions on the spot. Before Ewan came to the Digital World, he is quiet, compassionate, and above all emphatic to all life. He cares greatly for even the smallest forms of life, like a butterfly, and hates bringing anyone to harm. However, when AxeKnightmon opens a portal to the Digital World for Ewan and claims to be taking him to a world where nothing really dies or gets hurt, Ewan feels that he can act without remorse, as he isn't really hurting anything.
Because he thinks there are no consequences, Ewan treated the Digital World like a game and acted without regard to the safety of anyone in it. When he realizes that the Digital World contains living creatures capable of dying, Ewan feels intense remorse and regret for his actions as he joins with the Fusion Fighters United Army to redeem himself.
