Cardboard Box

The Cardboard Box is used in all of Snake's taunts in Super Smash Bros. Brawl. The Cardboard box was first introduced in the E3 2006 trailer, whereas Snake was hiding in it. It also has its own trophy. Before it was confirmed to be a taunt, it was thought to be his shield or his Down B. The box can be grabbed like an item, ending the taunt. In the Metal Gear games, Snake uses the box on his missions to sneak around without being spotted by guards. The fan community (especially in fanfiction) greatly enjoys making fun of Snake's affinity for the box, portraying him as a hobo or overly protective of his box.

Trophy Description
''A common, run-of-the-mill cardboard box that is somehow very effective at preventing detection by enemies. Hide inside it and enemies will walk on by. But put it somewhere too odd and you'll be discovered. You can move while in the box, but if anyone sees the box moving, you're in trouble. Both Liquid and Solid Snake have a deep affection for cardboard.''
