Adventure Mode: The Subspace Emissary (亜空の使者, Emissary of Subspace), sometimes abbreviated as SSE or shortened to Subspace Emissary, is a mode in Super Smash Bros. Brawl, similar to Melee's Adventure Mode. It was hinted at with the This world... Dojo update on July 20th, 2007, and fully unveiled on August 3rd of the same year.

Why It Rocks

  1. For the first time, the story mode has more boss battles (except with Master Hand, Crazy Hand and Gita Bowser) characters!
  2. If you want to do more power, than stickers can be equipped for each fighters. (Note: This is exclusive in the Subspace Emissary.)
  3. Many cutscenes are heartwarming and humor that is hilarious.

Bad Qualities

  1. Tons of plot holes:
    • By following the plot and map as presented, the movements of the antagonists are rather jumbled and nonlinear. The majority of these inconsistencies can be fixed by slightly reordering certain stages, as seen in the image to the right.
    • The Halberd attacks the Midair Stadium and Skyworld in the northwest, then The Battlefield Fortress in the central-west area, followed by The Forest in the southwest before attacking King Dedede's centrally located castle.
    • Bowser jumps from the Diddy Kong group in the North (after The Lake) to the Mario group in the West (The Lake Shore and The Cave), and then back to Diddy Kong in the North (The Swamp).
    • After Wario leaves the Midair Stadium, he captures Ness at The Ruined Zoo to the south, seems to turn back towards the west near The Lake Shore (where King Dedede ambushes him), and then travels back south past The Ruined Zoo to The Ruins.
      • In addition, as Dedede turns the Cargo around as he steals it, he is going away from The Lake Shore, not towards it where he meets the Mario group.
    • Presumably, it is impossible to enter or leave Subspace if there are no rifts. This, however, brings up multiple plot holes.
      • No rifts are known to have existed before the story begins. This raises the question of how Tabuu was able to bring Master Hand into Subspace to begin the story, or how he was able to mobilize the Army from Subspace onto the Isle of Ancients.
      • It is unclear how Dedede learned of Tabuu's nature and Off Waves, given that he would have to enter Subspace to do so (as Tabuu cannot leave Subspace).
      • It is never stated or shown how Sonic ended up in Subspace in the first place, because he was not affected by Tabuu's Off Waves.
      • It is unclear how the fighters managed to escape Subspace after Tabuu's defeat, as all the rifts that can be traveled through had been closed.
    • It is never shown how Mario and Pit moved from Skyworld to The Plain, or how Kirby and the princess he saved moved from Sea of Clouds to The Lake Shore.
    • It is unclear how Snake entered the Halberd.
