Title - "Let's press on and on and on!"
Fiora's trailer continues where Shulk's left off, with Metal Face's shadow looming over him.
"Fancy meeting you here...Monado Boy!"
Shulk says, "Metal Face...! I will make you pay for what you've done to Fiora!" and then runs toward him with the Monado activated, but Metal Face deflects the blow and knocks him back.
"Weak! Weak and pathetic!" Metal Face shouts. Shulk looks distraught as he holds his Monado in one hand, but then Zero Suit Samus grabs his other hand and says, "We have to run!"
The two run as this song starts playing:
Shulk and Zamus dash into a nearby cave (the one that's also a passage. Can't remember the name rn) as a thunderstorm starts (just like how the weather was when the person inside Face Nemesis was revealed to be Fiora). The two hide from Metal Face's vision as he flies past, yelling "Come out, come out, wherever you are~!"
Camera changes to the inside of a holographic visor, where a message appears to be typed to Fox and Falco.
"Fox, Falco, we're in quite the situation! Requesting aerial backup ASAP!"
That person is revealed to be Captain Falcon, who afterwards signals Shulk and Zamus to follow him through the other exit. As the three run out into the storm, Fox and Falco fly above in their Arwings, attempting to snipe the Faced Mechon, but are struck down. Luckily, Fox and Falco eject just in time. Of course, as the other three attempt to rush to their allies' aid, Metal Face spots them as lightning flashes.
"I found yooouuuuuuu!"
As Metal Face lunges his claws toward them, Face Nemesis flies toward Metal Face and attacks him. Metal Face says, "Don't you interfere! It's between me and Monado Boy!" He knocks Face Nemesis back as a familiar voice is heard.
Shulk murmurs, "That voice...could it be--" and is then interrupted by a vision as the "ominous" vocal part of the song above starts playing. The vision shows Metal Face firing an energy blast at the ground, causing an explosion and wiping Shulk and his allies out.
As the vision ends, Shulk says, "I don't know if I can do this..." as he prepares his Monado Shield, but just as the blast is about to hit them, the familiar voice shouts, "Shield Drones!!" and the blast disintegrates as Shulk and the others are unharmed.
"What?!"
Shulk slowly opens his eyes to see a short-haired girl with a face mask in front of him. He asks, "Are you...?"
This song starts playing from the selected start point as the figure takes off her mask:
Revealing herself to be none other than Fiora!
"No way...!" Shulk says. "Fiora...you're alive?"
Fiora, smiling, says, "Of course I am, Shulk." Turning around to Metal Face and priming her blades with a determined expression, she continues, "And I won't give up till we all make it outta here alive...!"
Fiora Engages the Enemy!
The six fighters rush toward Metal Face to attack, with Fiora leading.
Then gameplay footage begins as this song plays:
Dialogue:
Shulk: "Fiora...you're joining the fight too? I don't want you getting hurt again..."
Fiora: "Hee hee...don't worry about me, Shulk. With my new abilities, I'm very capable of holding of my own."
Reyn: "Leave it to Fiora!"
Fiora: "My Drone abilities can be used in many ways to ensure victory!"
Footage shows off her Drone swaps I proposed.
Fiora: "And that's not all!"
The song skips to the guitar solo at this part.
"Aiiirrr Fang!"
"Cross Impact!"
"Spear Blade!"
"Butterfly Step!"
"Healing Energy!"
"Double Wind!"
And after she grabs a Smash Ball --
"FINAL CROOOOOSSSSS!!"
And then footage showing off a Melia AT:
Melia: "Don't forget about me! You can call on me to assist too!"
Footage showing the Melia AT using Mind Blast to seal opponents' B moves (and yes, Fiora summoned her)
Shulk: "I'm glad you're here, Fiora."
Fiora: "Shulk...whatever lies ahead of us, we will face it...together."
Then the Smash Bros. logo appears.
Afterward, the screen fades to Shulk and Fiora sitting on the grass and looking at the stars as the other four try to dry up around a campfire as this song plays:
Fox and Falco look over at Shulk and Fiora as the other two fighters seem to have dozed off to sleep, but when they see Shulk and Fiora embracing, they decide to leave the two young lovers be.
