Юные Оптимус Прайм и Мегатрон превращаются из братьев по оружию в заклятых врагов.
The untold origin story of Optimus Prime and Megatron, better known as sworn enemies, but once were friends bonded like brothers who changed the fate of Cybertron forever.
But the movie is good except some moments. As a fan of the transformers I will rewatch it someday.
