@axavierhansz: Look at the panel? It clearly shows the paths he took were far out of the atmosphere, some of them even doubling the diameter of the Earth, it also showing no indication of him returning to the atmosphere.
Relativistic can be described as 10 - 99% lightspeed, I never said he was 1/4 the speed of light.
He was playing around, just look at his face he's not exerting himself whatsoever, and even if he is trying it doesn't change that fact that he has a transformation that makes him massively faster and then there are other characters who are faster still, which is the point I was originally trying to point at, none of this was to prove that Gotenks was relativistic himself, he's probably closer to sub relativistic, it was to prove that top tier DBZ characters can reach that speed, seeing as he could get close. And dude, it's not like I'm saying that Cell is relativistic, only Top Tier characters.
I don't know where you can find a Japanese scan, maybe you should ask Son Wukong, he probably knows of one.
Again, if he was as little as 1% light speed, he would be able to return to the atmosphere and back out again so quickly that it wouldn't be significant enough to draw. We're talking about a fraction of a second's deviation here.
Also let's be honest, drawing him that far out into space is just for the ease of drawing. Manga design take difficulty of drawing into account a lot, which is why the main cast rarely appears with uber-elaborate clothing. I can't find the quote right now but I remember one manga artist specifically saying he toned down his characters for ease of drawing. Can't remember which one at the moment. It would be much, much less cool and much more difficult to draw that one frame to-scale. For one thing, Gotenk's aura path would have to be massively shrunken. Whether a to-scale aura trail can even be seen that far out in space is highly debatable. For another, if Gotenks was actually flying close to the earth, it would be quite hard to actually draw him so close to the earth while still actually making it visible to the reader. When visibility becomes an issue, scale always goes out the window. Also, if that frame was to scale, then if you look at the other frames where Gotenk's aura is shown in relation to his body size, this would mean that Gotenks would have to be hundreds of kilometers wide. Clearly, he isn't.
tldr: that frame isn't to scale.
I didn't know that 10% light speed qualified as relativistic. I think you're right, it's possible that some of the characters are that fast. I originally thought that relativistic would be like 50%+ of light speed, where time warping becomes a serious factor (hence the word relativistic). But I totally concede that some of the characters might be 10% light speed.
