The idea that Saiyans are not native the Planet Vegeta/Plant

[Lord Frieza]

The idea of the saiyans being invaders of Planet Plant is not something new to Super. In fact all super did was add to the idea by giving us planet Sadala. The first time I heard of this idea was in GT, were we are told in a flash back by Baby that the saiyans invaded the planet and took it as their own.

But what I wonder is if this was the origin of this idea or did it have it's genesis earlier in DB's development history?

I'm not sure if it goes back farther than this, but it is part of the story of the 1993 video game Plan to Eradicate the Saiyans, from which the GT Baby story cribs heavily.

Toriyama implied pretty heavily that the Saiyans weren't native to the planet in his original memo on the Tuffles, which was 1989.

Planet Plant is a difficult planet to live on, as its gravity is unusually strong. However, two races live here. The majority of the inhabitants of Planet Plant are Tsufruian. Their bodies are small, but knowledge-wise they have a comparatively advanced culture and civilization. The other race has an unusually small population, but their bodies are large and strong. They are a primitive, warlike race called the Saiyans. Their biggest distinguishing characteristic is that they have tails, and every one of them seems to be a warrior.

[Picture of Tsufuru, with scouter and blaster gun, labeled “Tsufruian”. We see a colored version of this guy in DBZ episode 20 when Kaio introduces the Tsufruians] Due to the heavy gravity, they are about half as big as the Saiyans.

[arrow pointing to scouter on Tsufruian's head] This scouter, for instance, and other such things were originally Tsufuru inventions.

Wasn’t this stated way back in Z when Kaio is telling Goku about the Saiyans history?

No, it wasn't. He just says they both lived there.

[DBZAOTA482]

They originally lived together until the Saiyans overthrew the Tsufruians and claimed the Planet as their own (Planet Vegeta).

[Psajdak]

Does it even matter?

All relevant Saiyans came from planet Vegeta.

Just wanted to add little informaton that native planet of Saiyans as you all know is now called "Sadala" but before it was "Saiya" as stated in GT Perfect Files.
