The cannons mentioned above were already enough to make that Cthulhu Beast suffer.
But if that were all, the Cthulhu Beast figured it could grit its teeth and hold out for a while.

It was a special cannon capable of firing a brilliant, rainbow-like halo of light.
In terms of Attack Strength, the cannon was utterly unremarkable. Without its accompanying special effects, the Cthulhu Beast could have ignored it completely!
And yet this unremarkable cannon dealt the Cthulhu Beast its heaviest blows!

The so-called life core was not an actual organ. By the time a being evolved to the tier of Legendary creature, such physical weak points had long since disappeared from most Legendary creatures.
The life core inside the Cthulhu Beast was actually a
