The Zentraedi-Invid hybrid was a creation of Invid science in the years before the First Robotech War.
On Rel'nar, Breetai was captured by the Invid Scientist Tokalyan who obtained genetic samples from him. Breetai escaped but Tokalyan used it to make a creature with Breetai's body and the head that was am Invid Shocktrooper. Later, Chun'Da informed Breetai of another enemy approaching Mar'Peth and Breetai went out to battle it. Upon reaching the area, he saw Rel'nar ships shot down and was amazed to see a hybrid of Zentraedi and Invid. Breetai sized up the Hybrid and saw the Shocktrooper as its head was controlling the body but it was more intelligent than other Invid creations. Breetai used a Rel'nar fighter as a diversion to get in close and shatter its Shocktrooper head which killed the body. (Robotech: Warriors: When Titans Clash)
