Goku destroys the planet...
First of all. This is a matter of speed blitz. Goku is not nearly fast enough to react to Flash before he turns his brains into scrambled eggs. There is absolutely no proof to show that proves explicitly that Goku is even close to Light Speed. IT? It's not instantaneous. Second. Goku's never destroyed a planet. In fact, Goku SSJ4 had trouble lifting a city block. Could he? I don't necessarily doubt that, but it's never been shown. DBZ is wildly inconsistent anyways.
Also, Flash could travel back in time and kill baby Goku. The alternate time stream argument you made is asinine. While another time line would be created, Flash's TT ability can specifically travel within the same timeline, even though an alternate time line is being created.
He time travels its BFR.
Even if it was, which it's not, BFR'ing yourself and returning to the battlefield an instant later is not against the rules of this thread.
another thinks dark flash walter west, and kingdom come flash are the same as new earth flash.
Please, be specific, what users are you talking about, so they can give a response? This is ad hominem anyway, considering that you aren't debating the issue, you're attacking the people. Which just shows your asinine nature.
By the feats goku wins
LOL Goku barely has any feats of his own. It's always some DBZ building logic that makes Goku's "Feats."
Goku teleports which is instant
IT isn't instant. Prove to me that IT is absolutely instant. Oh, right, you can't. Even if it was, which it is not, he still needs to think it, and lock on to a Ki signature, which is not going to happen in this time frame.
Flash cant phase out peoples organs,
What makes you believe this? It's a pretty well known fact that all speed force users can scramble brains, and would do so especially without morals.
Hell 99% of the time wally cant even do his whole FTL bit without tie traveling by accident or entering the speed force and disappearing
Not to mention, to top it all off, his non-canon showings count.... Which includes the PC Canon. Which is way more than enough to demolish Goku virtually instantaneously.
And again this speed speed speed bs.
Where in DBZ/GT does Goku say "I'm massively FTL!" Never! It didn't happen. Beyond a reasonable doubt, Goku is not FTL. Unless you can prove it to me with scans, which you can't, because no such scans exist.
