@SpeedForceSpider: It's the speed I wonder about because even by the end of DBZ none of the characters reached light speed. However I've just done a lot of research and Raditz is still pretty damn fast. There was a reference I just saw online about how fast the Kamehameha wave was. The person stated that the wave travelled to the moon in about 5 seconds, which it did. He calculated that this meant the wave travelled at 1/4 the speed of light. Now I refer you to this old thread on this forum with scans that show that Raditz was able to dodge the wave for a little while before he had to turn around and face it. http://www.animevice.com/forums/raditz/1371/according-to-power-scaling-how-fast-do-you-think-raditz-is/323861/? . So that shows that Raditz is at least near 1/4 the speed of light, right?
Now i also say this in in the case of Naruto. Naruto has now been shown to travel faster than the Raikage who could himself travel so fast that even a fully evolved sharingan couldn't see him move around. Raikage also dodged an Amaterasu flame from point blank range. Amaterasu is almost instantaneous and in this case the flame had even already started appearing and he still dodged it. Also consider this, when Rock Lee took his weights off he was moving at speed faster than most characters eyes could see. Given that the other genin can still probably see things faster than we can because of their training that means Rock Lee was travelling pretty damn fast. Most people's eye can keep up with a large object, i.e. not a bullet or a fly up until about 20 mach. This would mean Rock Lee was travelling at the very least at about 20 mach. http://boards.straightdope.com/sdmb/showthread.php?t=580044 that's the reference I used, seemed fairly accurate. In reality however you may need to travel even faster, basically you need to travel so fast that the brain can't process what the eye has just seen.
Raditz is a lot more powerful though I agree, Naruto's probably mountain buster(maybe multi mountain buster) whereas Raditz is a moonbuster. But I'll let you guys try and figure out who's faster between Naruto and Raditz, I still say, in terms of speed, it may be closer than people think but given all the extra info I now say Raditz would take this.
