Overview

The first self-transforming, walking Transformers robot, developed by Robosen with Hasbro and a big crowdfunding-era hit. It walks, talks and converts to a truck on command, which is a remarkable servo engineering feat. As a biped it is a scripted collectible; the same platform continues in Megatron, Grimlock, Soundwave and Bumblebee.
