WMG / The Legend of Zelda: Phantom Hourglass

Zauz is this timeline's incarnation of Ganondorf.
However, instead of trying to kill Link, he's biding his time as he can't defeat Bellum due to his ancestor's power being weakened in The Wind Waker. So he helps Link defeat it in the hopes that with Bellum out of the way, he can Take Over the World.
  • But Hyrule Historia confirmed that this game is a direct sequel to The Wind Waker, so that wouldn't really make sense.
    • The World of the Ocean King isn't necessarily the world Hyrule is in.

Alternately, Zauz is the first of many male Gerudo
This was originally going to be "Zauz is the next male Gerudo", but Ganondorf's death isn't distant enough for that to be plausible. Perhaps Din lifted the restriction on male Gerudo, which is shown with Linebeck the Third having darker skin than his grandfather.
  • Zaus is actually a descendant of the Cobble Kingdom you explore later in the game, with Kayo being another male descendant.

The World of the Ocean King is Termina several hundred years later, flooded just like Hyrule was.

Bellum is this timeline's version of Majora.
Both Majora and Bellum terrorize a pocket dimension version of Hyrule, and they both also have those creepy yellow eyes. Perhaps an octopus accidentally grabbed Majora's Mask after Termina flooded.

The Wind Fish and the Ocean King are related.
Both are whales, both take you back "to your world" after they awaken, and then it turns out Link (and Tetra) were only sleeping for minutes at most. Too much coincidence.
  • Not really. Most of these are just not-very-subtle references - the world of the Ocean King was actually a real place, unlike Koholint Island.
