Among the earlier models of androids or bio androids, Dr. Blush made it so that each of them would have fail-safes in place.
It was during a time when her own Ki energy was still very small and her body was much too weak to contend against stronger life forms.
She did work hard to develop her magic and psychic energies at that time but it would not always be enough to contend against such difficult and sturdy opponents.
If there was a risk of them falling into the hands of others or turning on their creator one day then something needed to be put in place.
It was a time when Dr Blush was at her most cautious and did not allow freedom within any of her organization or with her creations.
It was not until she attained the status of a god with her magic and psychic powers that she no longer needed to worry about such things so she allowed freedom in her latest creations named Gene and Furia.
Most models in ALCHEMI were built from what Dr. Blush had created so they all carried similar designs.
Furia contained some memories of Dr. Blush that had been passed down onto her as Dr. Blush's incarnation while she had been taught some things by those she was being trained by within the psychic demon family.
There was a very tiny spot at the back of the neck that acted as a weak spot and would knock out each creation so a very precise hit was required.
Furia hit it very accurately with enough power which caused the bio android to drop to the ground. "So it is one of hers.. which scoundrel dares to send them here?!"
She was enraged that someone had started moving in on the Demon Realm without the orders of Dr. Blush and that there were some of the creations that were running around causing trouble.
She turned around to charge at Gul'Dan and his army that were defending his castle walls.
Her body moved with great speed as she jumped behind each one of the androids and sent precise finger jabs to the back of their necks causing them to fall.
Gul'Dan let out a mighty roar after coming out victorious. "Who is she? My new rival!?"
