Sea Serpent. Just because no one has ever made one.
I was referring to Gargantuan in size, but I get your point. I need to check out that Kickstarter. A Gargantuan Sea Serpent could double for the Black Magga in Rise of the Runelords, an encounter I found difficult to find a proxy.
Every set after Rise of the Runelords has had something that helped fill out the ranks:
Shattered Star - Hound of Tindalos, plus the Hill Giant, Wyvern, Wrath Demon and Elementals all proved useful.
Skull & Shackles - Sea Troll
Legends of Golarion - Sandpoint Devil
Wrath of the Righteous - Slime Demons, Demonic Familiar, even Areelu or Nocticula could be useful.
