That geniuly confuses me.

It was just supposed to be a natural upgrade but as it clearly showed, it was not really all that powerful. Gohan was beaten by Boo in like two chapters.

Anyway, for those who have missed it, Piccolo says that Freeza is more powerful now and Freeza also states that he now has a new form.

Well, didn't Gohan only lose because Buu had absorbed Gotenks at that point?

True, but Gohan got cocky thinking he was more powerful but never actually displayed it at all. He was pretty much on an even playing field with Boo.

Akira Toriyama wanted Gohan to kill Buu but things didn't go out as plan. I like Super Buu's other forms but Kid Buu felt like that they were pushing it. I like Buuhan as my favorite form of Buu and his battle with Vegito was fun to watch/read.

At the time before battle of gods Akira stated gohan was most powerful non fused character in the manga and vegito is most post powerful fusion character

Last time I check Akira Toriyama never stated that Gohan was the strongest non-fused character. That was just another old fan rumor that has been on the web for decades.

Weird cause I read it in my q and a leaflet that came with my viz media box set of the z manga

Edit: sorry just reread it and I learn Akira stated namekians are hermaphridites

Well seeing as how they have no females, and they can spit out eggs to reproduce, that is obvious. Bulma makes that comment about how boring it would be to be Namekian.

DBZ Bardock - It is a decent origin story even though it kind of messes up the continuity established in the show. Unfortunately, Bardock just really isn't that interesting of a character and the shown down with Freeza is lackluster. Overall, I'll give it a 6/10.

DBZ The History of Trunks - Meh, this one is quite boring and needlessly takes a 15 page manga chapter and stretches it out to 48 minutes. Why? Because that is the Dragon Ball way. How many Saiyans does it take a change a light bulb? Only one, but it takes 26 episodes to do so. Anyway, there is very little reason to care about Gohan aside from him having the name Gohan and we know he is Goku's son. There is no character development from anyone outside of Trunks, and even that is minimal at best. I give it a 4/10.
