Samus Without Armour!:

Go to Vs mode and pick Ness as your charater. and your opponent will be Samus. Put Samus's level on "1" and pick a level thats primarly flat. When fighting use Ness's UP+B move and hit samus with it. Right when you hit Samus press "pause." As you can see Samus has no Armour on and has a tail.
