Dorapan

The Mysterious Thief Dorapan is a mysterious thief from France that was modeled after the famous fictional character; Arsène Lupin from Lupin III.

He carries his own loyal sense of justice. Though often misunderstood for a villain, he always steals for a reason; which is to help the poor and vagrants. Despite being modeled after Arsène Lupin, his actions more reflect those of Robin Hood.
