Transformers: Generation 1 - Frenzy 3D Metal Puzzle Model Kit

Even though assembly models can’t transform, the process of building them from scratch is really interesting. Since you spend your own time and effort putting them together, the sense of accomplishment is overwhelming.

Soundwave count +1! After more than a week, I finally finished assembling it. It looks super cool, and I absolutely love it!

Soundwave is the Decepticons' version of Optimus Prime.
He wears a mask and commands a loyal cassette army:
Rumble, Frenzy, Ravage the mechanical dog, and Laserbeak the laser bird.
