A very dangerous ANMC and one of the most dangerous GOLEMs that Aya will fight, the Knight GOLEM is quite a different beast than the others that have fought up until this point. Their first attack is to grab Aya from behind and attempt to inject her with a toxic material, which inflicts Poison. They will then turn invisible and attempt to grab her again.
The easiest way of fighting them is to back into the corner and study them carefully. Frequently they will create a hologram which is a full color version of the Knight. Do NOT run through this as the real one will appear to attack Aya. The real one appears because it has a faint shadow and a buzzing sound can be heard. It will quickly cloak but the attacks should do enough damage to prevent it from attacking.
When it is going to charge Aya, a laser sight becomes visible. By avoiding this, Aya can also get some damage in there. When they fall to the ground and can quickly and easily finish them off.
