Why? The topic of the thread is about a hypothetical Gogeta from the Boo arc, not the one we saw in Movie 12. Not to mention, Goku in M12 is stronger than he was in the Boo arc, which means that the Gogeta from M12 could possibly be stronger than a hypothetical Boo arc Gogeta, making any of his feats from the movies invalid in this discussion.
The only instance of Gogeta we have seen is from movie 12, GT, and the video games, I can't think of a more reliable source of naming off his feats than material he has appeared in.
What proof is there that Goku is stronger in movie 12 anyways? Given that Gohan isn't in his mystic form in the movie but Gotenks exists I would say that it's more likely Gotenks defeated Fat Boo and it's only a short time after said events so I don't see why Goku would have made a massive leap to make Gogeta many times stronger.
In fact, Vegeta can't of powered up ANY since he died against Majin Boo and only now just got his body back and since the fusion dance requires both participants to be of equal power then Gogeta is based off Vegeta's level of power instead.
Okay, but you just completely ignored the statement I showed from the writer of the movies. Why should what other people from Toei say override what he says? If Toriyama's assistant said that Arale was stronger than Freeza and published it on some website, would you take it at face value despite Toriyama saying that Arale could give 23rd TB Goku a good fight, just because it's official?
Here's what Koyama actually said.
In handling the scripts for the films, what I always worried about each time was the problem of what to do about the opponent Goku fights against. That’s because, at the very least, they had to be stronger than [the ones from] the previous movie.
After much hard work, I was unable to come up with an opponent stronger than Broli, and fell into a rut where I made him appear three times.
That is to say, there’s the matter of questioning the idea of Broli as the strongest. As you are well aware, vehement opinions on the subject have been flying back and forth on this message board, as well as a variety of [other] websites.
For this time, Goku’s opponent, designed by Toriyama-sensei, was even a God of Destruction.
In the world of Dragon Ball Z, that’s a setting where even Broli, before the God of Destruction, would face a gap like that between a Yokozuna and the very bottom of the sumo ranks. That Broli, reduced to a pushover.
Only, from the impression I got of the character on the screen, Broli was scarier, no contest. Am I the only one who found that Broli looked overwhelmingly frightening? Or am I just biased towards my own creation?
Here he says that Broly was his strongest character which means that Bojack, Janemba, and Hirudegarn would not be stronger in his honest opinion, thus this contradicts his initial statement and indicates he only considers each villain to be stronger but not necessarily that they always are. Toei's movie website stated that Janemba is the superior of Hirudegarn and it's not as inconsistent as the screenwriter who admits he has some bias towards his work regarding who is stronger based on just how menacing the character is, I'm not sure how this is supposed to conclude that Janemba < Hirudegarn when the guy doesn't make it entirely clear.
