The Demon lashes it tail at the feline as it circles round, knowing that if it connected the target would be damaged greatly, it ignored the bullets that occasionally hit it in the head, and the projectiles were providing components for its use.
Khazrak hissed at the new assailant, the one with the blade of energy, it new what the blade could do yet it could be used for the Daemons advantage, sensing weakness in the attacker it tasked a part of its mind with infiltrating the attackers defenses and turning it against its allies.
Even as the sword was aimed at removing a limb from its body, the Daemon wasn’t quite quick enough and felt blade part flesh and bone with ease, the now separate limb flopped and spasmed a few times before going still, a glowing orb of plasma flew in, thrown by the human, and adhered to its stump but its flesh now flowed freely, covering and absorbing the plasma.
The raw energy from the consumed orb was distributed throughout its body, part of it going into a reserve for later, when it was needed. A tentacle lashed out, not aiming at anyone but instead grabbing the severed limb, which was pulled back into its flesh to be re-absorbed and reused.
And the foolish human was still shooting it, continuing to give its Flesh sustenance to heal and live.
Its mind easily diverted the Andalite mental attacks and pushed forwards, it wanted this one out of the way even if it did not eat that particular morsel. Some of the plasma energy bolstered its own mental energy and it worked at isolating the Andalite in his own mind before an idea struck it, it opened a pathway into its mind and started to force the Andalites mind in, if it succeeded it would have the Andalites mind trapped within its own and a Fleshling puppet to use. If it didn’t work, the Devourer would attempt to absorb and Consume the Mortal.
Meanwhile its own flesh was under new attack from a barrage of energy projectiles, too much energy for it to absorb easily, it expended as much of that energy as it could, causing its stomach to bloat and burst, sending forth a wave of disease infested little mites, known as Nurglings. A smile twisted the Daemons face, how it loved its little pets, its little dear Children. The hole began to seal itself as the Devourer turned and spat a mouthful of acid at the gun emplacement.
