Eugene Chaud

Eugene Chaud, known as Enzan Ijuuin (伊集院炎山) in Japan and as Chaud Blaze in English anime and manga, is an Official NetBattler and operator of ProtoMan.EXE. Chaud is extremely skilled due to the fact that he spends much of his time training with ProtoMan.

Chaud is son of IPC's (BlazeQuest in the English anime) president (Shuuseki Ijuuin), and the operator and creator of ProtoMan.EXE (Blues). His mother died while he was still young, and Chaud was forced into becoming the vice-president of his abusive father's corporation, a position which contributed to his initial cold attitude towards Lan Hikari (Netto Hikari). As the series progresses, he gains more respect for Lan, eventually becoming his friend, and also begins to open up to others, smiling more often. He does not, however, lose his serious outlook during battle, nor does he act impulsively before thinking.
