The Lab Assistants are used as minions who try and stop the hero Crash Bandicoot from foiling Cortex's plans. The Lab Assistants appear throughout the Crash Bandicoot series disguised in different outfits and costumes that usually correspond with the theme of a level. They also have their own methods of attacking Crash depending on their disguise.
The most prominent feature of the Lab Assistants are their glasses lens, which appear on all forms of Lab Assistants that Crash may encounter in the game. Later in Crash Bandicoot 3: Warped, a secret room in the central hub displays how the Lab Assistants are mass produced and sent into different time periods. This suggests that the Lab Assistants were actually robots created by Cortex to serve as henchmen. When Crash destroys Cortex's time traveling machine though, Cortex lost a line of his production of Lab Assistants. However, in Crash Bandicoot: The Wrath of Cortex, Cortex is seen again with more Lab Assistants, implying that Cortex may have more than one way of creating Lab Assistants.
The Lab Assistants were seen in the original Crash Bandicoot, where they are seen taking Tawna hostage. They served as henchmen for Dr. Cortex during the game. They use different types of chemicals and electricity to attack Crash in these levels.
Aside from the Lab Assistants that hold Tawna captive in the introduction, only two forms of Lab Assistants appear in the game.
- Beaker Tossing Lab Assistants - Various Lab Assistants toss chemical beakers in Crash's direction.
- Electric Barrier Lab Assistants - These Lab Assistants create an electrical barrier in front of Crash and walks towards him when he's in range.
