Meanwhile at 3D Land, Bowser Jr. was finding the heroes.

Bowser Jr.: "I'm really going to take down that bad man, Mario and his friends."

He traveled across the land looking and searching for them. Then, he noticed them at the canyon when the full moon was up. He was rushing there with his Junior Clown Car. They all noticed and were ready to put up a fight.

Mario: "Okay, here comes Bowser Jr.. He might be a kid, but he's headstrong."

Bowser Jr. fires his Clown Cannon, which ended with a huge explosion and our heroes. He flew up, got a big wrecking ball, and swung it at them causing another explosion. Mario soon ran up to him.

Mario: "I got it."

He saw that Junior had two drills to smash his head so Mario shield it until the drills broke it and Mario fell.

He soon turned the Clown Car into a go-kart and used his Clown Car Dash and dashed through the heroes.

Bowser Jr.: "Aw, yeah!"

He tried out his moves on everybody. He repeatedly punched Villager using his Stranded Attack, dodged Little Mac's Up Tilt and stabbed him with a fort using his Side Tilt, got Meta Knight with a Saw Blade by using his Dash Attack, ducked Zero Suit Samus's Paralyzer, dodged Mega Man's Side Smash and did his Side Smash on him, used his Side Special Move, Clown Car Dash on Captain Falcon, did his Down Special Move, MechaKoopa on incoming Luigi, grab and attacked Marth then did his Up Throw on and used Abandoned Ship and got him in the air using his Aerial Attack. Spider-Man and Mario got thrown to a wall.

Spider-Man: "Oww...!"

Mario: "Ooo...!"

Spider-Man was knocked out and Akame aid him. Mario soon get up and was shocked when he saw Bowser Jr. on the top of the cliff and he laughed evilly.

Bowser Jr.: "Ha, ha, ha, ha, ha!"

He called for backup and called his siblings, the Koopalings. It was Larry, Roy, Wendy, Iggy, Morton, Lemmy, and Ludwig.

Larry: "Ha!"

Roy: "Hmm..."

Wendy: "Yes!"

Iggy: "Ha ha!"

Morton: (Growl)

Lemmy: "Yay!"

Ludwig: (Growl)

Bowser Jr.: "Let's get 'hem, guys!"

Mario and friends are ready to fight them.

They all fought each other. Morton got Sonic and Rainbow Dash with Mechakoopa and his Front Air. Lemmy used his Clown Cannon on Kirby but he dodged when Iggy backed him up with his Clown Cannon and got him. Ludwig did his Down Smash on Luigi, Palutena, and Lloyd. Roy did his Stranded Attack on Fox and Lemmy and Morton beaten Fox too. And Wendy ran over the rest of them by using her Clown Kart Dash. Bowser Jr. then got the Smash Ball and finished them off with his Final Smash, Shadow Mario Paint. He painted an giant X all over. After that, Bowser Jr. and the Koopalings all left leaving our Heroes hurt.

Marth: "We all just got our butted kicked, huh?"

Ike: "And by kids too... how embarrassing."

Link: "I think it's best we keep moving forward."

Shulk had a vision and everyone listened.

Shulk: "We will meet a new challenger up ahead."

Ike: "Then, let's hope that he or she better not be a villain."

Spider-Man: "And let's hope that you don't jinxed it while we're keep moving."

They all left.
