Fake interviews and info

[Ussj Future Trunks]

Did Toriyama really only keep Vegeta around for popularity? And did he only add saiyaman because of the super sentai shows his son watched?
Also are there any grevious errors in the databook, enough to dismiss said errors as non canon?
And is the tarble special and episode of bardock accepted as canon?

Did Toriyama really only keep Vegeta around for popularity?

Hmm...sounds familiar, but I'm drawing a blank. In his Daizenshuu 2 interview, Toriyama says he didn't really like Vegeta, but he was very helpful to have around. That's the closest thing I can think of.

And did he only add saiyaman because of the super sentai shows his son watched?

Also in his Daizenshuu 2 interview, he says that he added the Ginyu Force into the story because his son loved Sentai shows. He doesn't mention Great Saiyaman, though Great Saiyaman has some Sentai inspiration too (though I guess technically he'd be a "Henshin Hero").

Also are there any grevious errors in the databook, enough to dismiss said errors as non canon?

Well, if they're "errors" then by definition they couldn't really be part of the canon. There's a podcast episode where Mike and I discuss the major and not-so-major mistakes in the guide books.

And is the tarble special and episode of bardock accepted as canon?

For good or ill, there's no big stone slabs establishing the DB canon. It's just up for individual fans to decide.

From what I know, the Henshin theme was quite popular in Japan since 70's, so I always thougt that Super Saiyans were needed in order for the show to progress.
As Zarbon and Freeza happened to transform, it was inevitable for the heroes to jump into the bandwagon.

I don't know any Shonen or Tokusatsu without henshin/transformation
