I’m sure you’ve seen it. As you watch a movie or play a video game, a character pulls out something from nowhere. Bugs Bunny and Wakko Warner reach behind their backs and bring out anvils or sledgehammers. Solid Snake and Link produce an endless assortment of gear and weapons from thin air. As Link demonstrates in the clever picture above, actually carrying around all that stuff is a physical impossibility.
The ability to pull stuff from nowhere is sometimes called the back pocket, a wry suggestion that the things characters pull from behind their backs were in their pants pockets the whole time. (This concept is particularly amusing in the case of characters that don’t wear pants.) In anime, the concept is called hammerspace. A comedic trope in Japanese animation is for characters to express anger by hitting something (or someone) with a large hammer produced from nowhere, making hammerspace the hypothetical place where all those hammers are kept.
The back pocket concept is usually played for comic effect in animation. Pinkie Pie, an exuberant character from a surprisingly awesome show about ponies, produces a wide assortment of items (including freaking cannons) from nowhere. Other characters know better than to question Pinkie’s defiance of physics.
In fact, when back pockets are used in any show or film, no one ever seems surprised.
In video games, back pockets are utilitarian rather than comedic in nature. The fact of the matter is that Link from the Legend of Zelda games needs his gear—all of it. Limiting his inventory would be a hindrance to the player, who would have to backtrack every time she needed something Link didn’t happen to be carrying at the moment. Constantly retrieving items, or plodding slowly under their weight, would be horribly annoying.
Thus Link carts around enormous shields and heavy explosives and iron-shod boots without any trouble. (Humorously enough, the iron boots only weigh down Link when he’s actually wearing them.) Solid Snake somehow sneaks through enemy territory burdened with cardboard boxes, sensor equipment and an entire arsenal of weapons (including massive rocket launchers). Every Final Fantasy character carries up to ninety-nine of every kind of weapon, armor and potion.
Where is all that stuff kept? Where does it come from?
Some questions, dear reader, are simply beyond answering.
