Title is a reference to the Octo Expansion credits theme, Into The Light.
Assumes Min Min is the ARMS rep (and the first Spirit promotion) and Neku is FP7, making Octoling FP8. Octoling is also the second Spirit promotion (Octoling Girl & Octoling Boy).
cross flash
This music starts playing:
Galeem can be seen in the sky as the camera shifts to underwater as Galeem fades into the distance. The camera keeps descending into the sea until you see an area that looks like the Fake Plastic Station in Deepsea Metro. Four characters controlled by Galeem - Mario, Luigi (who yes I know is canonically controlled by Dharkon in WoL; I'm trying to make this a counterpart to Hero's which had Dharkon controlling peeps normally controlled by Galeem, you'll see why Galeem though soon), Female Corrin (see Luigi and it was technically Male Corrin controlled by Dharkon in canon but I digress) and Female Byleth, patrol the outside of some mysterious building as green ink with a weird sanitizer like texture surrounds the ground ahead of them. (Now you see why I chose Galeem and their aura for this - the light blue represents Sanitization.)
Dialogue boxes appear throughout the trailer, with the mentioned characters' Octo Expansion portraits starting with:
Marina: What kind of place is this...?
Pearl: Yo, that light thingy up there is givin' me reeeeeal bad vibes...
Cap'n Cuttlefish: But we can't get outta here long as those guys are patrollin'.
Just then, a stream of peach-colored ink cuts across the green "sanitizer" ink, followed by a purplish-pink stream.
Cap'n Cuttlefish: WHOA!
Pearl: No way... could that be?
The music stops as two moving ripples form on the streams of ink, before:
"Oonay!"
This music starts playing:
A shot of purplish pink ink shoots from a Charger-type weapon and hits the Galeem-controlled Mario, sending him flying. The remaining "guards" turn their attention to the puddles of ink as two Octolings emerge from the ink: a female purplish-pink haired one with a female leather suit, and a male with peach colored hair and a similar suit, as the song reaches 0:10.
Marina: It's Agent 8!!
Title card shows at 0:12:
Octoling Paints The Town Pink!
Pearl: Excuse YOU, their name's Eight!
Gameplay starts as the song resumes, with various Galeem-controlled characters representing "Sanitized" versions of the Smash characters, even again, ones canonically controlled by Dharkon in WoL proper, like Cloud, Wolf, Lucina and Daisy, and actual canon Galeem-controlled Smashers like Captain Falcon, Ness, Bowser, and at one point Inkling with the yellow Agent 3 alt, a throwback to Hijacked Agent 3. Octolings use a variety of weapons the Inklings don't, like Dualies (which they can also use to dodge), Chargers, Umbrellas, and Splatlings, and their Bomb is a Toxic Mist which slows opponents down instead of the standard Splat Bomb. At one point, some DLC characters NOT controlled by Galeem appear, including the DQ8 Hero (pun on both of them being nicknamed Eight), and Neku. At one point, the Chaos Gold Female Octoling taunts with a Mii Swordfighter wearing Rex's Outfit, Male Byleth, Min Min and the Spring Man AT (Switch fam represent). Other alts are shown: Order Silver (Male), Mayo Pale Yellow (Female), Ketchup Orange-Red (Male), Unicorn Periwinkle (Female), and Narwhal Lavender (Male). (Those are all Splatfest colors in 2, with the exception of the first two which are taken straight from Octo Expansion.) Dialogue continues:
Cap'n Cuttlefish: You got a lotta weapons at yer disposal, kid. Use 'em wisely!
C. Q. Cumber: You're in Smash instead of the Deepsea Metro - test fai--
Pearl: OUTTA HERE, ya slimeball!
When the song gets to 0:25, cut back to CGI briefly as the Octolings get in their Ballers and charge in on the remaining three guards. Back to gameplay, the Octolings' Final Smash is shown - Baller. They can move around and hit opponents a few times before automatically detonating, instantly KOing anyone in point blank range. It can also be detonated early by pressing B. Gameplay resumes until 0:37, with another brief cut back to CGI as a Galeem controlled Agent 3 (Yellow Female Inkling) leaps down from the top of the building.
Marina: Agent 3?! How?!
Pearl: Don't have a seacow, Marina. I'll take it from here!
As the song resumes, gameplay continues as Octoling's stage, MC. Princess Diaries (the Final Fest Shifty Station) is shown, with the ruins of the NILS statue in the distance and Pearl and Marina in a helicopter above. It eventually cuts to Pearl descending from the helicopter with her special ready, and the Octoling getting her to whip out her Princess Cannon to blast a Galeem-controlled Agent 3 to the right with the Chaos ink blast (to the left, it's the Order ink blast).
Pearl: Boo-YAAAAAAAAAHHHHHHHHHHH!!!
the dialogue of Boo-YAHHHHHHH lines up with Pearl actually shouting it until the song ends with the fade out at 1:00 and the Smash Ultimate logo appears, stylized in the Octo Expansion's style ("Super Smash Bros" has a synthwave chrome look, and "Ultimate" is a neon pink).
... and there's more!
This starts playing as both Octolings, Min Min, and Neku stand at the cliffs before Galeem attacks, seeing all the Master Hands in the sky ready to take them down, before Galeem appears before them.
Pearl: AYO! We got you!
Off The Hook's helicopter hovers above them and Pearl leaps down in front of the fighters.
Pearl: Vocal chords ready!.... AYO, LIGHT THINGY!
It's pretty much the same as when Pearl uses the Princess Cannon against the NILS Statue in Octo Expansion except it's against Galeem, down to Pearl's BOOYAAAAAAAAH and the fluctuating turf war meters (Galeem's "Bad Guy" bar is a glimmering yellow instead) but when the Bad Guy bar almost completely overpowers the Good Guys bar, the trailer cuts to black and ends, for a suspenseful effect
