How Did Goku Forget His Purpose If....

[ドラゴ]

His tail had to be cut on numerous occasions and the full moon had to be destroyed multiple times? His purpose was to destroy Earth.. And he was doing that up until his tail had been cut or the moon was destroyed when he transformed. Before he hit his head, Grandpa Gohan was able to subdue Son Goku as a baby..... Were they (Planet Trade) relying on a full moon?

With all the great fighters on Earth, there was no way a Saiyan baby (unless Great Ape) at a battle power of 2 could defeat ALL of them...Yet, Raditz and the PTO felt he was more than capable of destroying all the inhabitants on Earth?

Well the average powerlevel on the planet was 5 according to Raditz and Raditz was also surprised that there was someone of Goku's level in power. I think that it was assumed that Goku would be able to take care of Earth as a regular Saiyan without the need of Oozaru. They just didn't factor in people like Gohan, Tienshinhan, Roshi, Tao Pai Pai, etc. Because they were in such a minority their scans of the planet didn't really reveal them.

I would assume it is in the Oozaru's very nature to be destructive anyway. I can't remember if it is in the manga but Vegeta said in the anime that the first SSJ destroyed himself when he became an Oozaru and destroyed the planet he was living on. So Goku's "purpose" and the Oozaru's nature may be the same goal but they aren't for the same reason.

Well, Goku's actions in the Buu Arc let to Earth being destroyed.

Well the average powerlevel on the planet was 5 according to Raditz

That 5 was based on one person, and you can't take an average from one person. Raditz never made any claims about an average battle power, or made any indication that he thought the farmer was of average power. However, if you want to make an average based on Raditz's abysmally low sample size (farmer, Piccolo, Goku, and Gohan), Earth's "average" battle power reading upon his arrival would be 342.75. And that's just at rest.

I'm afraid I don't understand your question. Goku knows of his original purpose since Raditz told him.

Really? I remember Raditz saying something like an average battle power of 5.. And of course you can't take an average from one person which is why I'm saying he is quoting a number they previously worked out. I doubt they would send a Saiyan to a world as a baby if they hadn't of done any background check on the powerlevels of the planet. What if they sent Goku to planet Namek? All the Namekians there were well in their thousands. Goku would have died pretty quickly. Goku was sent to Earth because the Saiyan's had already assessed that Goku could take it over.

I looked at the strength checker and it seems like Raditz didn't say average in the manga, perhaps it was in the anime only? Or possibly a dub. Either way, I distinctively remember someone quoting an average battle power. I don't think I'm imagining it.

Chapter: 195 (DBZ 1), P10.2
Raditz: “"Oh, battle power 322. So there are guys like this here too? But naturally, you're no match for me..."

Here Raditz is demonstrating genuine surprise that there are people who are close to Goku's level of power. Obviously if they had done their research 20 years ago then that wouldn't be the case and there would be a lot more weaker powerlevels. In fact, Kame-sennin, Tsuru-sennin and Gohan were probably the strongest people alive back then and their power levels would be somewhere just over 100.

Wait how do you get an average of 342.75 when Gohan was 1 and farmer was 5...?

Gohan's initial battle power reading was 710.

[Gaffer Tape]

Hmm, that is a good point. Not sure if Gohan's 710 could be considered "at rest" or not, but, then again, when we get that reading, he's doing nothing but crying in a pod. We never get a reading of what Gohan's busting out of the pod moment was. But I personally always considered his bottomed out reading afterwards to be that he'd shot his wad, so to speak, rather than what his standard "at rest" level was. But, obviously, you're free to disagree.
