Other than having a pair of brown hare ears, Elliot shares no likeness to the March Hare, upon which he is based. He first seems willing to help Alice, until he points his weapon at her and says he wants to "test his new gun". But later in the manga, Elliot comes across as a kind and sweet person with the willingness to kill people without hesitation. Elliot is dedicated to serving Blood, due to the fact that Blood helped Elliot escape prison for a terrible sin.
