Presenting the Voyager Class Dinobot Slog - Sludge - from the Transformers Age of Extinction toyline - AOE.Slog is based upon the Dinobot Sludge. Michael Bay in his infinite wisdom decided that, as with Slug / Slag, that it would be better to call Sludge, Slog.
To the uninitiated, Slog is actually a real character in the Transformers timeline. Slog is a Deception Pretender - a robot that hides within the hide of some hideous looking beast and one of the combiners who formed Monstructor. The Decepticon Slog also formed the artistic movement called Slogism which depicted the war between the Decepticons and the Autobots in mangled horrific forms.
Michael Bay decided to remake him as a Dinobot. To his credit, Bay also remade him from being a Brontosaurus - a creature that actually never existed and was created out of the erroneous combination of two distinct dinosaurs - to being an Apatosaurus. It's interesting how much our knowledge of dinosaurs has grown since we first saw the Dinobots in 1984.
