When Vegeta lands on the retreat spot to become healed after the battle with Goku, the 3 people who go out to see Vegeta are the same 3 people who are seen in Freiza's spaceship at about the same time. And when the Ginyu Force takes off, there they are in the place where the Ginyu Force takes off from. After Vegeta lands on Namek, another space pod lands and you never find out who it was. Unless if it was Kui because he was on the retreat spot with Vegeta and then with Freiza when Vegeta lands. When Vegeta faces off with Dodoria, in one scene his eyes are completely black When Freiza orders Zarbon to find Vegeta after hurting him but not killing him, Zarbon orders a purple henchmen with yellow spots to help him in the search. Later on in the episode or the next one the purple henchmen with yellow spots becomes a yellow henchmen with purple spots. And when he reports in he becomes a purple alien with yellow spots again. In Guldo's flashback, Vegeta didn't have a tail even though it happened before the battle with Goku. When people die in Dragonball, if they keep their bodies, their bodies are fully repaired, like when Tien got his arm back. But, why didn't the scars on Yamcha's face and on Tien's chest didn't go away since they were physical damages. When Mr. Popo tells about Kami's childhood in Yunzabitt he says that Kami barely had any food but Dende told Gohan, Krillin, and Bulma that Nameks only drink water to survive. Mr. Popo must be going through memory loss from old age.

Saiyan's hairstyles are strong but in water they move with the tide, but when Vegeta was in 400X Earth's gravity his hair was just as normal.

In the Japanese version, Cell was able to regenerate himself because of a unique cell in his head, but Goku blew off his head and he was still able to regenerate. The American version fixed the problem saying that Cell can regenerate from ANY cell in his body. When Vegeta is knocked out and Trunks is dead, we see their faces and their eyes are black.

In the beginning of Dragonball Z, Raditz kills a farmer and we see that same farmer, or one that looks exactly like it, even with his bird, over and over again. In the Android Saga, Vegeta trains without a shirt on and there are scars all over his chest and even on his arms, but in the Buu Saga, his outfit doesn't have sleeves and there are no scars. In the Cell Saga, when the army come to destroy Cell we see that the logo says TM and in the next scene it says MT.
