Death- The Last Sleep?
No.
It's the Final Awakening.

Note: (Epilogue of the Previous Chapter)

After getting hit by the Point blank Hyper Beam of Gyarados and left practically torn apart everyone thought that the 'Skarmory' was dead. Right?

But No.

It wasn't dead.

And it wasn't a normal "Skarmory" neither. It was a mutation. A Mutated Skarmory.

The Excessus present inside the Mutated Skarmory starts to condense and its ready to heal the Demons wounds.

Slowly, cell by cell, tissue by tissue it starts healing. As the tissues start to condense and settle, the monster is reborn, like a Phoenix from the Darkest depths of Hell.

Every Excessus filled creature is able to go through this process......

.....EVEN THEM.
