Transformers: EarthSpark is the latest incarnation of the well-known animated series. Nickelodeon's approach to the iconic robots in disguise places the action firmly on Earth, with many classic Transformers like Optimus Prime and Megatron working side-by-side with a group of humans and some new Earth-born robots known as Terrans. It's one of these humans -- Dot, the matriarch of the Malto family -- who has some of the show's most compelling relationships.
