Overview
Converting a giant Autobot dinosaur is the whole experience of this Studio Series Grimlock, which changes from robot to dinosaur with movie-inspired detail. A mace and a spiked knuckle attach as accessories, and instructions are included.
Sheer size and the dinosaur mode make it a centerpiece for a display. The limit is the long conversion and the figure's dimensions, which call for a wide shelf, and the battery note in the listing is unexplained.
Who it's for
Transformers fans who enjoy a big conversion project will find a detailed figure. Anyone expecting a quick change, or a small toy, should choose a smaller class.
Pros and cons
- Dinosaur alt mode
- Mace and spiked knuckle
- Very long conversion
- No manufacturer warranty
- Battery note unexplained
Performance notes
The long conversion sequence and the joints decide how the figure holds its shape, so slow, careful handling matters. Accessories attach in either form, and the listing describes high poseability for display.
