Dragon Ball Super

[Janice]

Huh...I really thought Super Saiyan just completely overwrote Kaioken. It makes no sense that Goku wouldn't have used it before now if that wasn't the case. I mean, yeah, they said it damages his body. But he's been in quite a few situations where Earth or the entire galaxy have been at stake should he lose. And he's always just scraped by, when he apparently could have just Kaiokenned instead.

That said, the episode was still awesome and Hit is the goddamn coolest.

Himself decades ago?

This is functionally the same as the Other World Tournament. Escalating it to "universes" is a meaningless distinction, because they're all still just aliens.

That accusation ignores the fact that it was the obvious choice in the first place. When your main character is the strongest character in the universe, the next logical step is other universes.

It's like a fanfic creating a Super Saiyan 5, and then accusing him of stealing the idea later if he adds a Super Saiyan 5.

No, it's not the "obvious" direction of the story. If he had any creativity left in his body, there are literally an infinite number of other ways the story could progress. The first mention of another universe was in BoTG, and the Other World is not really the same thing here. Your argument is that he had this idea in his pocket for the past 20 years, and coincidentally a group of fans had the exact same idea, and then he decided to use his idea shortly after they released DBM because why not? Sure, it's possible, and has happened before (Calculus, electricity, etc...) but very unlikely in this scenario. It would be blatant plagiarism if not for copyright laws and what not.
