"And with Corrupette and Splashzilla now less of a threat to the two kingdoms. Bowser Jr starts a new life with a newly wife and the Mushroom Kingdom is once again safe from the koopa armies events, at least for now..."

Okay okay okay,this will be the last wedding drawing I do with these two I promise. I just had to draw them getting married for real, they deserve it. For once a real royal wedding in the Mario universe that isn't forced.
I put Bowser Jr in a normal human tuxedo, idk I don't like the Odyessy one much for my AU. you can also notice Toadette's dress is a bit different as well. I also went for a really mario theme for the bg since they're getting married out by Peach's Castle/the Mushroom Kingom's main area.
