Dark Link. He's only appeared a handful of times in Zelda. Yet he has become a pretty popular character to fans. Why? I'm not really sure. Mostly because Dark Sides are cool. They're cool in Star Wars, cool in Spiderman, cool in Metroid, heck, even the Bible. And after reading some theories on Dark Link, I saw another connection. That connection being The Matrix.
Now, many see Dark Link as many different things, some see him as a ghost of a past warrior, or simply a reflection of Link. I even read one theory that said that Dark Link is Link of the other timeline. However, what most people believe is that Dark Link is a creation of Ganondorf. Either as a hazard or an actual second in command (this is seen in
AoL). However I think Dark Link is somthing much more simple.
The Matrix, for those of you who haven't seen the trilogy, is basically about a computer program that people are literally plugged into without their knowledge. While this doesn't relate to Zelda this next part I believe does. Now in the Matrix, the main protagonist, Neo, has qualities similar to Link. But also does Dark Link have qualities similar to one of the main antagonists, Smith.
Now this may seem a bit strange. But, there are many similarities. First off, they are quite literally the same thing, only opposite. In the Matrix, Smith is the opposite side of the equation, his only purpose is to balance out the goodness in Neo. The same could be said about Link and Dark Link.
Secondly, skill in combat is equal. I'm sure many remember the frustratingly difficult battle in
OoT. This is mostly because Dark Link moves and attacks EXACTLY like Link.
So my argument. That the Zelda Universe (no pun intended) is much like the Matrix in that certain laws must be followed. The main being equality. I believe that Dark Link is "the other side of the equation" whose sole purpose is to balance out the goodness in Link. The same could possibly be true regarding Termina VS Hyrule, Dark VS Light or Zelda VS Midna (in
TP specifically) and in termina the Goddesses VS the Four Giants.
So to put it simply, Dark Link is the opposite of Link because the Universe has to find a balance. With Good there must be Bad, with light there must be Dark. That Kind of thinking.
I appologize if this is a bit muddled. It's late and I'm tired. I'll possibly edit tomorrow.
