Koopalings not related to Bowser any more?
According to a recent interview with Shigeru Miyamoto that is, where he says that (presumably) the old TV shows/anime/comics were wrong and that the current story is that the Koopalings are not Bowser’s children. Here’s the original quote:
Our current story is that the Koopalings are not Bowser’s children. Bowser’s only child is Bowser Jr and we don’t know who the mother is.
Well, it looks like Nintendo has basically retconned away the old Super Mario Bros 3 US manual backstory altogether by now, first was the whole Brooklyn thing now the Koopalings aren’t classed as Bowser’s children any more.
Of course, some people have come up with ways around this. Maybe it turns out they’re related to Bowser in some other way, like how Diddy Kong is often referred to as DK’s nephew or something. Maybe they’re his stepchildren by different mothers and were adopted early on.
But according to Miyamoto, they’re not his children and that much is certain.
