Transformers - 20th Anniversary

[deadpool0207]

Im trying to figure out what series this head goes to I had a hard time looking for it on the transformers web site
Its about as big as the power master head but I think the figure it came with may have had some sort of sound action because his mouth plate moves?? IDK!

It's the 20th anivversery version it has no sound but did have a light up matrix and is considered the greatest prime of all time.
