hmm, is there any real backstory for FSA Dark/Shadow Link? (I think I'll just refer to them as one name, either one I feel like at the time) If not then not then it could be theorized that he is the same as any other Shadow Link in any other game(a representation of what Link fears he may become or the darkness inside of Link) but replicated many times by Ganon in order to cause trouble and hinder Link's progress, same basic concept as what I said above (and what Wolf said but in fewer words).
Actually Shadow Link did have a backstory of sorts. We found out that Ganon created him, but how did Ganon create him? Well one of the maidens talk about Ganon having a dark mirror which he can use to simulate a reflective opposite of the person he is trying to oppose. So since Ganon was trying to oppose Link, our righteous hero, then he created a dark opposite, or dark twin as the game calls it, in order to wreak havoc and free the wind mage Vaati. As for the other Dark/Shadow Links, well it never was explained, but I think FSA shedded a great deal of light (or shadow) on the subject. Also there was only one Shadow Link in FSA, the other Links that looked like Shadow Link were called Linkalikes (you know the ones that you could defeat with a mere single strike).
Now I am going to give a brief answer on each question and I will eloborate on this later. Okay call me lazy, but I will get around to this.
1. Are Dark Link and Shadow Link the same person? I am thinking that they are one in the same, and suggestions from Tekky and others seem to give a plausible answer on the case.
2. Is he evil enough to be the final boss in a game one day? Well if one believes that Shadow Link and Dark Link are one in the same, then he was already the final boss in the AoL. Other than that I think that he should be more of a test for Link than to actually resurface as a final boss again. Though if I did see Shadow/Dark Link again I would like for him to have a meanacing demeanor and have an aura look on him much of what was shown when Sora had to face Anti-Sora, for those that have played Kingdom Hearts.
3. Is he evil at all? If he is the dark reflective side of Link, I would most certainly say that yes, he is evil.
4. Maybe he's just a figment of Link's imagination? This could be one possible scenario, but FSA has placed Shadow Link as just a dark reflective twin of our hero, but it is an interesting proposition.
