As the last Core Class figure from Kingdom, Hot Rod ends not only the Class on a high note but the whole of the Kingdom line. Transformation is involved but intuitive, much like Core Class Starscream. I should mention that like most Core sized car Transformers, the ease of Hot Rod's transformation will factor on how tight the ball joints are, as that can make things easier or harder. Overall, Hot Rod is a fine figure and a great addition to your Core Class collection.
