We begin with a shot of a floating island, seemingly the Isle of the Ancients from Brawl.
We cut in to see the entrance to a high-tech facility going down beneath the island, with Samus's gunship visible on the side.
We cut in further to a corridor of that facility, dark and empty--save for Zero Suit Samus and Richter, who walk past.
We see a door open from the interior of a room; Samus and Richter are standing on the other side. They walk in.
After looking around the room for a bit, Samus and Richter stop in surprise as they see something--Mega Man and R.O.B., hooked up to machinery on the wall.
Samus sees a terminal a short distance from the robots, pointing it out to Richter. He shrugs, and she signals him towards the robots.
Samus goes up to the terminal and starts typing at it. On the monitor, we see a diagram of Mega Man outlined in green appear. We then see a diagram of R.O.B. appear, also in green--until it suddenly turns red as a loud crashing sound rings out.
Samus turns to see Richter has torn R.O.B. off the wall. R.O.B. doesn't seem to be damaged, but is still offline. Richter gives a thumbs-up, and Samus turns back to the monitor.
Samus then gives a small jolt of surprise as something else appears on screen--a diagram of an unknown figure (looking like a human in a cap) outlined in red. Samus signals Richter, and he walks up, still holding R.O.B.
In a dark corner of the room, a figure points a large white weapon at the two. Three missiles fire from it; Samus and Richter hear them fire and turn to see.
Cut to a more well-lit cavern, filled with houses and a few bunny-people--until the cave wall close to the ceiling explodes, with Samus, Richter, and R.O.B. being flung out. The bunny-people turn and run.
Through the hole in the wall, we see the attacker standing at the ledge. They drop their large weapon and grab a blue gun from their hip. They jump down towards Samus and Richter, who struggle to get themselves battle-ready. (R.O.B. is still turned off.)
The figure lands and points his gun at the two.
Quote Takes the Shot!
<insert random gameplay, showing off Quote's wide variety of projectile moves; the Cave Story theme plays>
We see some gameplay of Quote fighting Zero Suit Samus and Richter on his stage, Mimiga Village, which then leads back into a cinematic.
Quote is struggling against the two, and Richter leaps at him--but then gets hit by a volley of white projectiles from off-screen, knocking him away. Quote and Samus turn to see the new figure, holding a red gun.
Curly Guns Down!
<insert more random gameplay, particularly establishing that Curly is an alternate model for Quote, until the end; Running Hell plays>
