This is a beast that is not used to backing down, not accustomed to battling anything that would not be killed. There were no other beasts in its hierarchy save one, and that was ally and...friend? Something there was never time to linger and establish rank with in any case.

The squirming, muscular beast continues to worm up until that point where the saurian-like jaws finally manage to clamp down into the thick main and get a grip on his neck. Even if this was a scruff, there's not a lot of loose flesh to scruff and that would have had to happen by the main. This...

This elicits a protesting rumble and a cut off roar. Something that seems crossed between outrage and surprise. The beast is still lacking its usual affinity with fire, so it has no other recourse than physical. And though it still seems to wiggle, the struggles are beginning to lessen.

Exhaustion? No. An internal realization that he lost and he's not happy about it.

The tail lashes with irritation, but it's no longer trying to whack the side of Sephiroth's face.
