Ernest

Ernest is the 5th of the five main robots the player repeatedly saves during their work at Death Trap Incorporated. He's an old legacy model, which - according to the Announcer - the company has to keep around to interact with some older interfaces. It's implied that copies of Ernest aren't produced anymore and that this is why the remaining ones are given special treatment. In fact, Ernest is usually the easiest robot to save in a level, and in several saving any other robot without saving him is not possible.

Design
Ernest has a bulky green shell and wears a top hat that doubles as a chimney, from which he occasionally emits smoke. To further add to his elitarian appearance, Ernest wears a monocle. A stabilizer wheel keeps him from falling over due to his weight and hints at his age.

Ernest's attribute color is green.

Trivia

 * As Ernest runs on a steam engine, he was chosen by Poltergames to be featured in their announcement of the Steam version of RoboTraps.
