Green enzymes are enemies in Test Subject Green. They are one out of three types of enzymes in the Test Subject series, the other two being blue and orange enzymes.  

The first green enzyme was made when a blue enzyme and an orange enzyme were mixed together by the professor at Xeno Industries. It was with the first green enzyme that the professor made other variations of green enzymes.

Game information


Test Subject Blue

After Blue, a blue enzyme completed 25 of the professor's tests, the professor mixed the blue enzyme with an orange enzyme and created a strong orange enzyme, but two seconds later it transformed into a green enzyme.

Test Subject Green

The professor used this green enzyme to create other green enzymes that he tested Blue against. The professor was attacked during one test, and his lab and Xeno Industries was looted. Doctor Nastidous, who was responsible for this, made other types of green enzymes and tested them against Blue in his own test container.


There are six versions of green enzymes, two of which were made by Doctor Nastidous.
