Let them fight!

@Andy Willow It's because the entire universe was destroyed at the end of Galaxy 1 & a new universe got rebuilt. Bowser & Jr. are from the old universe while the current Koopalings are new universe & thus not directly connected anymore.

Hey, it's more of an explanation than Nintendo gives.

@Billy_G
How about both?

And this is further evidence that Hollywood is either out of ideas or under Chinese control.

I'd love to see a modern Shadowrun that's similar in play mechanics to the SNES version, but a 3d shooter like Cyberpunk 2077.

Not sure if Jo is a little late to the party with this. I've seen some Reddit pages who have been hyping this battle since Sunday.
I was off line Saturday and I'm sure thats still a day late to the reddit party.

@BakaGrappler
Yes, You think AMC is going to go under just because of a world wide plague?

Wait. Movie theaters still exist?

All this reminds me of, is that they retconned ALL of the Bowsers kids into mere groupies and made Bowser Jr, the sole offspring.
