Aiber

Aiber (アイバー Aibā), whose real name is Thierry Morello, is a professional con-man in the employ of L. He plays the role of Eraldo Coil (エラルド・コイル Erarudo Koiru), one of L's detective aliases, during the investigation of the Yotsuba Group. Aiber uses his initial "A", just like L, when communicating through computers. After L's death, in the manga he is killed by Light with liver cancer. In the anime Aiber dies in front of his family. He is voiced by Takuya Kirimoto in the Japanese anime, and David Orth in the English version.

According to Obata, his editor told him that Aiber was a "sarcastic, comic relief" character. Obata said that he wishes that he could have drawn Aiber to be "more comedic." Obata believes that if he drew Aiber and Wedy to look "a little bit more original," Ohba could have included the characters in a larger role in Death Note.
