Why did the Saiyans need Goku?

[funrush]

A while ago, I was watching some Saiyan Saga episodes of the anime, and I realized, why did the Saiyans need Goku if they could just plant some Saibaimen? Were they out of Saibaimen to use, and figured that Goku was as strong as one?

Raditz had missed his little bro.

[Gozar]

In my opinion, what it ultimately comes down to is that Saibaimen are great as disposable allies, but lack real fighting intellect. They're not trained, they don't have much of a strategy aside from "Attack; If that fails, blow self up". In addition, they are not Saiyans, they do not possess the raw ability to gain so much from a single fight.

They needed him for his Oozaru form. Four Oozaru are better than three Oozaru & some Saibamen.

[DoomieDoomie911]

The Saibaimen have absolutely no technique, that's why the needed another Saiyan. If they had used Saibaimen the dumb little creatures could have been far more easily outsmarted and, ultimately, defeated.

Raditz travelled to Earth for 1 year, he may not even be aware that Vegeta and Nappa happened to have some Saibaimen on their hands.

It's also possible that the planet they were attempting to conquer didn't have soil suited for Saibamen cultivating. When Nappa was planting them on Earth, he commented that they'll grow well in the soil, suggesting that, like any other plant life, if the conditions weren't right, they might not grow very well, if at all.

[Mystic Gohan]

Raditz considers Goku weaker than he should have been. Prolly should have turned out stronger than a Saibamen by that time.

[Darkprince410]

The way Raditz acts though is that even though Goku is weaker than he predicted that he should be, that he's still strong enough to get the job done.

[FNF]

Vegeta was having his prince fantasies and realized 'what's the point of being a prince without subjects?'

[Toadster]

Goku was at what... 300 something? 400 something? Expelling all his power, he was around 900. In Oozaru form, that would have been 9,000. Even 3,000 is better than 1,200.

[DBZAOTA482]

The more the merrier.

[dprez]

Four saiyans are better than three. Freeza himself even feared that a gathering of saiyans could threaten his empire. After their home planet was destroyed and their entire race was pretty much wiped out, I'd say they had plenty of reason to add Kakarotto to their crew.

[Dabooyaka]

I think Goku's Ozaru transformation is what made him look worthy in the eyes on the saiyan.

[soulnova]

I think Goku's Ozaru transformation is what made him look worthy in the eyes on the saiyan.

...And then Raditz realized he didn't have his tail and started cursing left and right.

[Godo]

I think Goku's Ozaru transformation is what made him look worthy in the eyes on the saiyan.

Yup. Remember that at that time, Oozaru was the only transformation that could give tremendous power. Even weak ass babies could be of use in conquering planets with the Oozaru transformation
Then the SSJ transformation came and made it obsolete.

[caejones]

Which is a little funny, since baby Goku would have only had a battle power of 20 as an Oozaru. If he went on a rampage that reached civilization, the Royal military would probably have chunked a misile at him and knocked him out, if it didn't kill him, and have their own baby saiyan for research.

[Toadster]

Then the SSJ transformation came and made it obsolete.

If only the Saiyans kept their tales and were able to go Oozaru and Super Saiyan at the same time... Then they'd be really strong.

From the point of view of the manga alone, probably wouldn't make any difference.

x50 boost tacked on to a x10 boost is a 500x boost in power from base form.
