AX-1 android

The AX-1 Android, otherwise known as the Humanoid Android System, [HAS], was a pioneering product designed by Aperture Science for military and commercial purpose.

Features
The AX-1 was the most advanced android of its time, and it was equipped with and Aperture Science VI, whose generic name was Max for males and Rebecca for females.

GLaDOS MK1
The AX-1 was built several years before the production of Aperture's first true AI, GLaDOS. It was thought to be wise not to equip these androids with this AI due to the new nature of AIs to human society, therefore they remained with the generic VI.
