Research Facility (Part II) is a stage featured in Adventure Mode: The Subspace Emissary of Super Smash Bros. Brawl. It is the 19th overall stage, although it continues directly after the first part of The Research Facility.


The stage begins with Zero Suit Samus and Pikachu going after Samus's Power Suit, which was somehow stolen by the Subspace Army. Upon arriving at the room where the suit is stored, the duo are ambushed by two Shadow Bug clones of the Power Suit. After the copies are defeated, Zero Suit Samus uses her Plasma Whip to break her suit out of its glass container. By breaking the glass, however, she set off numerous alarms, and R.O.B.'s swarm the room. After defeating the enemies, Samus put on her suit and the duo sets off again.

Eventually, after a rather difficult maze of platforms, most of which are moving, they come to a large room where they are attacked by Ridley. The boss swoops down and grabs Samus, scraping her against the wall as sparks fly off the power suit. He drops Samus only when Pikachu jumps up and zaps him with Thunder. Samus and Ridley land next to Pikachu, and Samus's suit is still giving off sparks as though it is malfunctioning or damaged; nevertheless, she emerges unscathed in terms of damage. Ridley was covered in electricity when falling, though he only seems to give himself a headache when he lands face-first. He too looks unscathed. A boss battle ensues.

After defeating Ridley, the pair exit the Facility and appear on the grassy surface of the Isle of Ancients. Samus spots R.O.B.'s carrying Subspace Bombs into another building, so they decide to pursue. This takes them to the Subspace Bomb Factory, accessed later on during Adventure Mode: The Subspace Emissary.

Clearing the stage unlocks Samus as a playable character, though Samus does not replace Zero Suit Samus, as the latter can still be selected before certain stages by pressing the grab button while highlighting Samus.


Glice is the only enemy to first appear in the stage.
