Mario went off to pursue Bowser at the Super Mario Maker stage. When he got there, Bowser was already there waiting for his arrival.

Bowser: "So you finally decided to show up, did you?"

Mario: "Where are your intentions, Bowser? Why are you working with Master Hand again?"

Bowser: "It's not my job to tell you. Me and the other villains have own purposes with him."

Mario: "I won't let you achieve your goal."

Bowser: "Tsk, tsk, tsk. You are always contradict me and my ambitions. Which is why we are going to settle this in Smash."

Mario attempted to throw his fireball, but Bowser fiercely and confidently punched it away.

Bowser: "Bwah, ha, ha, ha, ha!"

Bowser came running towards him and knocked Mario offstage with a Dash Attack. Mario was able come back onstage.

Mario: "I won't stay down that easy."

Bowser used Bowser Bomb, but Mario rolled away and executed a Side Smash. Bowser was able to keep his ground and was charging his Side Smash, but Mario caped him and did a Down Smash, making him fall in a pool of lava.

Bowser: "Rrrrrraaaah!"

Mario side taunted.

When Mario was about to leave, he heard a loud rumble and when he turned around, he saw Bowser in his monstrous form, Giga Bowser.

Bowser: "You shouldn't turn back when you had the chance."

Mario: "Bring it on!"

Mario was running towards him in ambition, while Bowser was just standing there waiting for him to strike.

Bowser: "Not even a challenge..."

Mario then got the idea to get ahold of Bowser's tail but was smacked into a wall by the tail.

Bowser: "Ha! What do you think this is, Mario? Super Mario 64? This is Smash Bros! I'm not falling for that again."

Bowser launched Mario across the stage and was going to land into the lava until Mario Maker created a platform for Mario to land on.

Bowser came running towards him coming in with s Dash Attack. Mario rolled to the other side. The Mario Maker came and dropped in a Smash Ball. Mario got it, and Bowser didn't like it.

Bowser: "Minions...Attack!!!"

Bowser's minions tries to ambush Mario but the savior of the mushroom kingdom beat them easily.

Bowser: "Dang it!"

Unexpectedly, Bowser's Giga form has wear off.

Bowser: "Damnit! I'm not finished yet!"

Bowser launched 1,000 fast bullet bills towards Mario, but Mario had a proud and confident smirk.

Mario: "Oh yeah! Hiyyahhh!"

He unleashed his Final Smash, Mario Finale.

Bowser was defeated and trophylized. A Warp Pipe appeared and Mario went through it, going back to Final Destination. Soon after he left, Bowser's trophy disappeared.
