These characters, siblings modified into cyborgs by Dr. Gero, initially served as antagonists. Their power levels vastly exceeded those of previous adversaries, posing a significant threat to the Z Fighters. Their transformation involved cellular modification, granting them immense strength and an inexhaustible energy source.
Their introduction marked a turning point in the narrative, forcing the protagonists to surpass their limits and seek new levels of power. The siblings’ rebellious nature and eventual shift towards a more neutral, even heroic role, provided complex character development and broadened the scope of the Dragon Ball universe. This development offered unexpected allies and reshaped the dynamics among the core cast.
