Our verdict

A very large Grimlock for movie fans and adult collectors who want a dinosaur mode and a long, involved conversion. The conversion is demanding and the listing carries no warranty.

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

Pros

  • Mace and spiked knuckle
Cons
  • Very long conversion

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.
