Sludge

Stomping onto the scene in the very first issue of Marvel's Transformers: Generation 2 in 1993, Sludge arrived at the dawn of the Modern Age alongside some of the most iconic names in Cybertronian history — sharing pages with the likes of Optimus Prime, Megatron, and Starscream. Crafted by the legendary Transformers scribe Simon Furman and artist Derek Yaniger, Sludge has kept remarkable company across a catalog that stretches all the way to 2025, appearing in both Transformers: Generation 2 and the Transformers Compendium. A character whose presence has endured for over three decades, Sludge is a fascinating piece of Transformers comics history for any collector who wants to trace the full arc of the franchise on the printed page.
