Daisuke
Despite his childish appearance Daisuke is actually a very skilled hacker, and excels at making powerful Data Bugs. His specialty is making chimeras, unique monsters that are composed of bits and pieces of other monsters. However he also has several childlike traits, and can be very stubborn and impatient at times. When one of his creations is destroyed he frequently yells at its attacker for cheating, despite the fact that he is a cheater himself. Out of the four hackers, he is the most sadistic.
