Anime: - Dragonball Z, Vol. 6 - Immortals

Dragonball Z, Vol. 6 - Immortals The Earth's Special Forces show their newly developed powers in their victory over the plant monsters known as the Saibamen, but unfortunately, that was only the prologue to the real battle against the evil Saiyans, Vegeta and Nappa. Soon, the Earth's Special Forces discover that their best attacks barely faze the Saiyans. Where is Goku?!
Customer Review: Classic (Saiyan Saga, NOT Ginyu/Freiza)
Picking up from Doom (Vol. 5), Immortals continues the Saiyan Saga with a vengeance. The Z force is stalling for time, hoping that Goku will arrive soon to aid in the fight against Vegeta and Nappa. In a bid for time, they agree to fight one-on-one with the Saiyan's Saibamen - little green trolls that are as strong as Goku's late brother Radditz. The relative ease with which the Z fighters are able to combat the Saibamen skillfully illustrates how much the fighters have learned in the past year of training. However, the Saibamen fight dishonorably and manage to mortally wound one member of the Z force and kill a second. A third member of the Z force sacrifices his own life in a desperate bid to protect his friends from the vicious Nappa, but tragically the sacrifice is in vain.

This is an extremely poignant set of episodes. I especially like the internal tension in Gohan - though he has trained this past year to fight, he has never actually been IN battle and he is realistically terrified by the cruel Saiyans.

Note that this DVD is the Saiyan saga - not the Freiza/Ginyu sagas. I'm not sure why so many reviews here reference Capt. Ginyu - some strange Amazon weirdness? Also note that this is the 'cut', English-dubbed edition, which I (personally) prefer, but some do not.

LATER EDIT:
It becomes clear why there is confusion in the reviews - the two DVDs "Doom" and "Assault" are apparently set up to share reviews. How very odd. Below is my review for Assault:

There are a few major changes things to note here. Unlike all the previous English DBZs, this DVD has been left uncut, and includes both Japanese and English speakers and subtitles (including English for the hearing-impaired, which is greatly appreciated on my part). The uncut nature of the DVD will appeal to purists, but I'm afraid I personally prefer the cut versions because the extra violence is not to my taste. This is instantly obvious in the battle between Frieza and Nail - the scenes linger painfully over Nail's brutal wounds, and blood, sweat, and tears abound liberally. I find the overall effect distasteful, but it's something I'm willing to put up with for my fondness of the series. Just be aware of the change here. (The above will be true for all the remaining DVDs in the Ginyu/Frieza saga.)

Assault is powerful in many ways, not the least being Nail's selfless sacrifice to lead Frieza away from his beloved father and mentor Guru. Nail realizes that the fight he is facing will be hopeless and brutal, but he does not flinch from the coming task. Though Frieza tortures him mercilessly, he refuses to reveal the Dragonball password, and he endures as long as he can in order to spare his dear Guru.
Customer Review: This is when the story picks up
This saga picks up with Goku fighting the Ginyu Force after they damn near beat Gohan to death. After easily dispatching them the survivor retreats for his leader Captain Ginyu. This saga is very short. 2 DVD's with 7 episodes. It adds alot to the story and sets the stage for the coming battle with Frieza. The fights could have been better. Still I recommend this volume to complete your collection. Its 3 action packed episodes.
