Oozaru training and etc.

[Jackal puFF]

So I was watching the saiyan arc where Vegeta turns into an oozaru. How is it that he was able to control this form? How do you even train yourself to do that?
Also, can you do other techniques besides squeezing? Haha, but seriously Vegeta didn't do one ki attack in that form.. Do you think Goku would have been able to go kaio-ken if he was in oozaru form and had control? One more question..What happens a super saiyan with a tail looks at a full moon? Do they turn into a golden oozaru?

I actually don't know, but maybe knowing that you have the transformation makes a difference? Or because he's an adult, it's easier not to lose control?

Also, can you do other techniques besides squeezing? Haha, but seriously Vegeta didn't do one ki attack in that form..

He did. He fired that big mouth blast before Goku used the Genkidama.

Do you think Goku would have been able to go kaio-ken if he was in oozaru form and had control?

I don't think they are compatible.

One more question..What happens a super saiyan with a tail looks at a full moon? Do they turn into a golden oozaru?

Maybe, but it wasn't a requirement.

[Fox666]

How is it that he was able to control this form?

He may have just trained for it.

Another possibility is that he can do it because of his evil nature. Kuririn mentioned that as an Oozaru, Goku and Gohan go bersekr because they reveal their true saiyan nature.

Also, can you do other techniques besides squeezing? Haha, but seriously Vegeta didn't do one ki attack in that form..

He can use Bukujutsu and fire a Ki attack from his mouth, I don't see why he wouldn't be able to use any of his techniques while in that form.

Do you think Goku would have been able to go kaio-ken if he was in oozaru form and had control?

Goku never used the Kaio-ken again once he transformed in Super Saiyan, so the source of power of both Kaio-ken and transformations are the same. However Goku could still use a Kaio-ken times 20 and double his strength...

One more question..What happens a super saiyan with a tail looks at a full moon? Do they turn into a golden oozaru?

In Dragon Ball GT, more-or-less.

Going by the manga, I don't see why he wouldn't transform in a Super Oozaru, however it probably wouldn't be any stronger than a regular Super Saiyan.

It's worth to note that while in Dragon Ball GT the tail of a Super Saiyan is gold, in other sources (such as Episode of Bardock) it doesn't. We also get a glimpse of a Super Oozaru outside of GT in New Dr. Slump:

[Senzu_Bean]

I personally think Vegeta did actually train in Oozaru to control and master the form. Like Goku told Trunks that at first he couldn't transform into Super Saiyan and had to master the form to control it. I think the same would apply to Oozaru.

About Super Saiyans and tails if I'm not mistaken Mr. Toriyama said the tails are a disadvantage once the Saiyan achieve super-power. If you would discard GT then a Super Saiyan would probably lack a tail or he/she would simply transform into Oozaru since they're two separated transformations.

Interesting to note in Mr. Toriyama's notes to Broli he wrote that it was fine whether or not he had a tail.

Goku never used the Kaio-ken again once he transformed in Supe would Saiyan, so the source of power of both Kaio-ken and transformations are the same.

Why would you think that? One is a ki technique like so many others while the other is Saiyan transformation. Would Kaio be tapping into Super Saiyan power while developing the Kaio-ken?

I might be wrong, but I remember Goku's tail not turning gold in GT until he reached Super Saiyan 3. Everyone used to call it a coloring mistake, but I never thought so, and it seems like it's intentional on Toei's part by this point.

I think Vegeta and Nappa (who I assume can also control his Ozaru, on account of his elite status) first trained themselves to eliminate their tail weakness before training (perhaps in the form itself) to control Ozaru. And, as Fox666 said, it might be because of their evil nature that allows them to handle the form better than Earth-grounded Saiyans, who don't go around conquering planets in their Ozaru forms a lot and mostly transform by accident. Plus, the fact that Vegeta's an adult may make it easier for him to handle, as we only saw Goku and Gohan ever transform when they were children.

And yeah, we see Ozaru Vegeta fly and fire a mouth blast at Goku before he used the Genki-Dama, and there's nothing that suggests he wouldn't be able to use any of his techniques in that form.

And no, I don't think Goku would've been able to use Kaio-ken in a controlled Ozaru. I don't believe they can work in conjunction with each other.

[Fox666]

It seems that according the Daizenshuu, Goku and Gohan can't control their forms because they are not accustomed to it.

When those who are not accustomed to it become an Oozaru, the enormous power causes them to loose their reason.

About Super Saiyans and tails if I'm not mistaken Mr. Toriyama said the tails are a disadvantage once the Saiyan achieve super-power. If you would discard GT then a Super Saiyan would probably lack a tail or he/she would simply transform into Oozaru since they're two separated transformations.

Interesting to note in Mr. Toriyama's notes to Broli he wrote that it was fine whether or not he had a tail.

Not exactly, Toriyama mention that they are so strong they don't need a tail anymore. That matches Daizenshuu description that the tail "will often suddenly grow back if they are in danger".

I suppose Broli is more about the character design. But it's interesting that Toriyama doesn't seem to care if someone who can transform in Super Saiyan has a tail.

[DBZGTKOSDH]

Also, can you do other techniques besides squeezing? Haha, but seriously Vegeta didn't do one ki attack in that form..

Vegeta used Bukujuttsu and Ki Blast from his mouth Gohan used Ki Blast from his moth, Golden Oozaru Goku could use his mouth as a flamethrower, and Oozaru Baby could use his normal attacks. In the Sparking games, the characters that could control the form (Vegeta, Nappa, King Vegeta, Baby) could use their normal attacks, while those who couldn't control the form (Raditz, Bardock, Selipa, Tullece, not sure about Goku) could just use mouth Ki Blasts.

[Haji]

I remember that Episode of Bardock special, it was weird that his tail was not yellow, The aura of SSJ is like a light, it has a yellow or golden color, when this aura is all over they're body it should make the tail yellow, thats why they're hair turns yellow. If you notice they're clothes light up and turn yellow a bit.

[Fox666]

In the manga the Super Saiyan aura has no color and not different from a regular saiyans. And in the Kazenban covers, Toriyama colored the auras blue.

The clothes shouldn't change, but apparently in the anime it does when Goku transforms in Super Saiyan 3.

when this aura is all over they're body it should make the tail yellow, thats why they're hair turns yellow.

Huh, the hair is not different just because of the aura, they hair itself change.

[Jackal puFF]

Oh right..I totally forgot Vegeta did that mouth blast thing. I wonder if he can do that in base form..

Haha that super Oozaru looks pretty ridiculous.

[Fox666]

Oh right..I totally forgot Vegeta did that mouth blast thing. I wonder if he can do that in base form..

Gohan don't, so perhaps that's a instinct-driven technique. But we have seen Nappa or Gotenks firing blasts from their mouths, so maybe he does.

[Kingdom Heartless]

I think any character can fire off ki from wherever they choose... it's all about what they feel comfortable with. Using the hands is probably just easier. Keep in mind Goku was able to fire off a Kamehame-Ha blast with his feet. And numerous characters fire from their eyes.

[Piccolo Daimao]

Daizenshuu description that the tail "will often suddenly grow back if they are in danger".

Why would that be? Either way, as an out-of-universe explanation, I always thought that it was for plot requirements. Goku grows his tail back in time just in time to escape Giran's attack at the 21st TB, and later, in the Saiyan arc, Gohan grows his back shortly after Vegeta blasts everyone back with his shockwave.
