Cave here. Man oh man. Wow. Greg's multiple universe theory was dicey, but you're pulling through with flying colors. We're all very proud of Greg. [pause] Oh, and you. Click to listen — Cave Johnson

Greg is, during the events of the Perpetual Testing Initiative, the assistant of Aperture CEO Cave Johnson.

Originally, he was written to appear during Portal 2's single-player campaign, however, he was replaced by Caroline prior to release and was considered to be cut from the game before being added back as Caroline's replacement in the Perpetual Testing Initiative DLC.

Overview

According to the The Final Hours of Portal 2, one of the reasons Greg was cut was to eliminate the cost of hiring a new voice actor that only played a small role, instead of reusing Ellen McLain to voice Caroline. Doing this also provided a background for GLaDOS, due to the usage of same voice actors.

In the universe of the Perpetual Testing Initiative, Greg's words are not entirely audible and comes off through the speakers as muffled.
