|Actually in the manga it shows Goku having the kaioken aura just prior to king kai saying that Goku is already using kaioken. This means that King kai was only refering it to that time and later. And he was only explaining it to Yamcha, Tien and Chioutzu since they aren't able to see Goku's aura. But do you really think that they were able to sense Goku's ki from that far away? I mean King Kai even had to tell them that the spirit bomb was a sucess. Plus it showed Goku with no aura whatsoever deflecting Frieza's attack. He also charged Frieza. Your kaioken "burst" theory is wrong because Goku charged Frieza meaning that he'd have to be able to hold it off for a couple of seconds. And since Vegeta wsn't able to do anything even CLOSE to that it shows that Goku would have to have used the kaioken x10 (going by your theory). And since he'd have to hold it off for a couple of seconds without a doubt he'd show a sign of panting. Yet he was absolutely calm and it looked as if it didn't require even an ounce of chi. Also your theory is a failure since such a thing was never stated...|
Wait a second, you say my theory is a failure because it was never stated? Yet, I don't see anything anywhere where your theory was proven correct.
Anyway. As I stated in my previous post, Goku's Kaioken aura was only shown around the time that King Kai pointed it out since it was meant to be a surprise to the readers. Like I said, what would be the point in showing the Kaioken aura if it was intended to not be noticed? That's really not good proof for you to be using. Now if King Kai had said that Goku just began using the Kaioken x10 when he realized that he couldn't beat 50% Frieza normally, then it would be clear proof for you. Instead, he merely said that Goku "was already using the Kaioken x10". Stating such a thing obviously points to Goku using it since the beginning, or at least already before Frieza went to 50%-And since Goku would have been killed if not for the Kaioken, even before Frieza powered up, it would be most logical to say that Goku was using it the entire time.
The Z fighters have been shown to sense power levels from far away, usually when those power levels suddenly increase substantially, like Frieza and Goku's powers did.
Again, Goku not having the Kaioken aura while he was deflecting Frieza's blasts shows nothing since showing the aura would spoil the surprise that Goku was outmatched by Frieza.
Yes, Goku was using the Kaioken x10 the whole time. Goku using the Kaioken in bursts isn't instantly wrong just because Goku had to have stayed in Kaioken for a few seconds at a time at certain points. At this stage of his development Goku was obviously able to stay in Kaioken for much longer periods of time than he used to. Remember how risky the Kaioken was back when Goku was fighting Nappa? Remember how reluctant Goku was to use it? That was only Kaioken x2. He was much more worried about using the Kaioken x3 against Vegeta, also. Yet, look at the scene where Goku uses Kaioken after fighting with Ginyu (in order to inflate his power to much higher than Ginyu's). He uses it without even the slightest bit of strain at all, and he stands (hovers) there for a while to give Ginyu a scare. While the Kaioken x2 isn't quite as much as the x10, that scene still shows how far Goku's mastery of the Kaioken has gone. If Goku could casually use the Kaioken x2 without even showing any signs of fatigue whatsoever while having a power of 90,000, then why wouldn't he be able to use the Kaioken x10 off and on during a fight when his power was around 300,000? I mean, even several seconds in between Kaioken uses would be enough time to keep your body from breaking down, and Goku's body obviously became a lot more durable after his training on his trip to Namek. And at that time, his power increased around 9x. What this shows is that with more power, one could handle the Kaioken better. Now, since Goku increased by about 4x from his zenkai after the whole Ginyu thing, he would be able to handle the Kaioken even better than he could while fighting Ginyu. At that point, he would be able to use the Kaioken x10 with much greater ease than you may think.
While I'm usually the one who wants statements as proof (like in the Krillin vs. Tien debate), it's not always possible to find one that relates to certain debates. This is one of those debates. Neither side has any available statements that directly relate to the debate, but that doesn't meant the argument is instantly dead. Though no direct statements, there is more proof for my side. For example, the whole zenkai thing and how much of an increase it gives on average. A usual zenkai increases one by anywhere from a fraction of one's current power to 3-4x one's current power depending on how close to death one was and/or another couple factors, and it's been shown several times. It also seems that one receives a larger than normal zenkai if they use a Senzu bean. A zenkai of 33x is substantially higher than any previous zenkai by Goku, Vegeta, or Gohan (and in fact by FAR the largest one in Dragonball Z, with Vegeta's zenkai after fighting Recoome being the second), and is a pretty ridiculous belief. It just seems like a wacky excuse to place reasoning in the Daizenshuu's power levels.
Also, you skipped the other parts of my post. Most specifically, the explanation of the scene where Goku stands on top of the ship and doubts his ability to defeat Frieza. Once more, why would he doubt being able to beat him if they were even close to even in power? Seeing as how Goku had the Kaioken to substantially increase his power, and his mastery over the technique was far and beyond what it used to be. Add onto that the fact that Goku never dreamed of Frieza having as much hidden power as he actually had, and you'll see that they couldn't have been anywhere close in power normally. Goku was shown to be able to sense exactly what Frieza's current power was at, and he even figured that Frieza was holding back. Yet, he grossly underestimated how much power Frieza had stashed away. Yet, he still thought that he might not be able to win, even before witnessing Frieza's 50% power. So please, if you can, make sense of that situation. I can't. Goku using just the Kaioken (x2) alone would give him plenty enough power to defeat Frieza if they were truly close to even, let alone the Kaioken x10 or x20. At Kaioken x20, he could have defeated Frieza with a couple of hits, or a single Kamehameha.
