I actually started replying to every single one of your comments. Then I thought, what the hell is the point of this thread?
And god, stop comparing anything Naruto to Db. Wave struggle was in DB, way before Naruto even existed. What you've referred as preparing "rasengan" is actually a combined wave attack, you can see it firing in the end. The other one, when he hits the Namekian in the stomach is either a Ki ball kept in hand (as it exploded in the end), or just an empowered punch with ki, something like what Goku used to kill King Piccolo.
I think you missed a major part of DB and DBZ, stuff like that happened a lot. ;P
I'm sorry but i agree with you both. DB had those effects long before Naruto did, but when he caught the Namek with the gut shot I 2 was thinking Rasengan. lol
