The R-100 series can easily be identified from the other robots by their silver-coloured armour, cylinder-shaped heads, and arms hovering by their torso. As the series progresses, the robots get bigger and supposedly more advanced.
A robot from the R-100 Series has made an appearance in every TimeSplitters thus far. They are advanced robots created for The Machine Wars. The robots are often bulky and powerful, as they are designed to fight in war. Interestingly enough, they are always featured at the last level or towards the last in story mode.
It is also important to note that there is a character with a similar name as the R-100 series; however, Robert One-Oh-Seven does not count, as he is merely a human under the delusion that he is a robot.
