Tron was formerly involved with Dr. Faker's business, and has sworn to take revenge together with his followers III, IV and V. Usually he acts very childlike, enjoying cartoons and playing video games to the point where he bursts out in fits of laughter. However when he is talking to his followers, or announcing his plans to others, he is more mature, while always maintaining a smile on his face. (Source: Yu-Gi-Oh! Wikia)
