This is the Henkei Series of Classic Transformers. Each one of them are awesome. Very details in Robot Mode and also in Vehicle Mode. Fully articulated and posable in any form and great for display.
The previous release from Takara under the ENCORE Series is on G1 TF where is it a 1984 released version. The ENCORE is a bit stiff, point of articulations is lesser and not as posable compare with the Henkei Series, however there are still G1 TF fans out there who does collect them. Forgot to mention that ENCORE Series is more pricier then the Henkei Series.
Hasbro also came out a similar toy lines for this Classic TF, the only comment that I have is that Hasbro paint job is not as good as Takara and it does not come with a Trading Card and the color scheme is a little bit different. The only exception I give is on Bumblebee as I personally think that Hasbro's made a more beautiful Bumblebee than the Henkei version.
