ToyWorld was one of those new comers that completely impressed me. Their first release was a update of the G1 Throttlebot, Rollbar. Grindrod seemed to fade into obscurity only for years later to be announced that all the figures in the series would be a combiner! They followed up that release with Hegemon, an awesome update to G1 Megatron. Since then they have also released their take on the mighty G1 Dinobots as well.
