RED-1

RED-1 was an Atlas-Class Titan fighting for the IMC that appears in the Free the Frontier cinematic trailer, where it attacks a Militia Pilot at the end of the trailer. In game it can be seen in the Hammond R&D labs on Corporate. It is possible that it was originally supposed to be a character in titanfall's scrapped single-player campaign since almost nothing is known about it and it only appeared in a trailer that was likely made early on in development.
