Toxitron is a fictional Transformer character associated with the Transformers franchise, often depicted as a toxic, unstable, or corrupted variant of a larger robot warrior. In series and toy continuities where he appears, he is typically portrayed as a dangerous combatant with a green-and-purple color scheme and a hazardous, pollution-themed design. His role is usually that of an antagonistic or morally ambiguous figure, serving as a weaponized counterpart or evil clone rather than a central hero, and he is remembered mainly as a niche, collector-focused character.
