*Bowser is the first REAL bad guy to join you in the SSE.
*In this game, Kirby can eat any item except pokeballs. But Kirby can eat party balls, which may have Pokeballs in them, but since Kirby can eat them, that means they have no pokeballs in them.

*Meta-Knight's Right+A (Not smash or dash attack) can actually perform 3 combos if you press A 3 times when using it.
*Sonic, Jigglypuff and Yoshi are the 3 fastest characters in Brawl (Jigglypuff and Yoshi are on this list because when they use their Rollout and Roll attacks, they go REALLY fast.

*You are never forced as a Mario or Pokemon character (Unless you die enough times)!
*It took 2 days for Luigi and Ness to be revived when they were wearing the DeDeDe badges but it only took Kirby a few hours!
*In the game, if any character even Squirtle is in the water for a long enough time, they drown-WAIT! Isn't Squirtle a water-type Pokemon that can swim?

*Ice CLimbers are the last veterians to join you in the SSE.
