The Kamerian Heart was the original intended boss fight for Dragon Rock in Dinosaur Planet. It represented the Frankenstein remains of the last great Kamerian war dragon that fell in battle against the Krazoa over Dinosaur Planet's orbit, and became something of a god figure to the dinosaur inhabitants, who believed that they were spawned from it. One of the dragon's descendants, Drakor, becomes aware of its presence on Dinosaur Planet and seeks the assistance of General Scales and the SharpClaw to take over the planet and begin channeling all of its magical energies into the Kamerian Heart within Dragon Rock using the Force Point Temples, in order to revive it and thus allow Drakor to use its huge destructive powers to destroy the planet and seek vengeance against the Krazoa, as well as conquering the entire universe. Inside the Kamerian Heart was where the area's SpellStone resided, and thus Sabre had to defeat the heart in order to acquire it, and after an encounter with Drakor, would need to escape from within Dragon Rock before he is trapped there forever.

The Kamerian Heart is noticeably the only boss fight present in the leaked December 2000 build of Dinosaur Planet to be entirely absent in the final Star Fox Adventures. Drakor, whose role was repurposed as General Scales' mutant bioweapon, would take over its role as Dragon Rock's boss that Fox must defeat in order to obtain the SpellStone. In turn, Andross would take over Drakor's role as the final boss of Star Fox Adventures.
