The very first Link and Ganon were around the same age, and best friends. At some point in their lives, they accidentally released a demon of some sort and then took it upon themselves to track down and defeat it. They succeeded in doing so, but just before it died, the demon cursed them to be infinitely reincarnated as each other’s enemy. Ganon also slighted the demon in some way, and so was further cursed to always lose, and to also be a demon himself in some of his future lives.

The Clawshots are the same in both Skyward Sword and Twilight Princess. After SS, Link gave them to someone in Skyloft or forgot them there, and they stayed up there until one was dropped to the surface, where it fell into Lake Hylia and was eventually swallowed by the Deku Toad pre-Twilight Princess.

Is the Wind Fish from Link’s Awakening. They’re both flying whales, have a strong connection to a magic song, and at some point are possessed in some form by an evil creature (Bilocyte/ or the Nightmare).

The fact that Tetra’s a pirate in Wind Waker makes me think that, moments prior to the great flood that sealed Hyrule underwater, the Goddesses instructed the Royal Family to isolate themselves of any trace of royalty once the kingdom was sealed. Simply having the Royal Family protect the Triforce of Wisdom was a dead giveaway for Ganon, so adopting a completely new way of life that eventually led to Tetra’s (and presumably her mother’s) life of piracy was the only other way they could keep it (and the bloodline) safe. Kind of like the Hylian version of the Witness Protection Program.

I think that in every species in Majora’s mask, they all have a Link-like hero that comes from a long line of heroes, as I think Link himself does. I think that’s why Link was able to get the masks of those species to transform into, because they shared the same kind of destiny and bloodline.

Because if you notice, Darmani states that he comes from a line of Goron warriors, and Mikau mentions that he has “hero’s blood”. The Deku’s next citizen bound for glory was the Butler’s son, so Link took his place when he was transformed.

Along that same line, I believe that all the Links are related as father or grandfther and son or grandson.

I think that the blue fairy that appears as the pointer in Twilight Princess is Navi. TP Link is the child of a OoT Link, who died trying to find Navi. OoT Link became the Hero’s Shade and remains in the Lost Woods and years later, Navi happened to come across him. Hero’s Shade then tells Navi about everything that happened after she left, and about the son that he left all alone. Feeling guilty, Navi promised Hero’s Shade that she’d watch over his son. That’s why there is a fairy as a pointer.
