Theo Bell is the main protagonist of the Dragon Ball CT series. Theo is a defender of Earth and informally advises the Z Fighters. Throughout his life, he trains hard and strives to improve his abilities as a fighter, while at the same time using his amazing strength and skills to uphold peace. He is heavily burdened by the loss of his parents and while the Z fighters often look to him as a leader, he prefers to act more as an adviser and teacher. These qualities make him the perfect example of an unwiling-hero, though not necessarily the perfect role model, due to deep seeded inner demons.
