It was his deep loyalty to Megatron — and his deeper dedication to destruction and mayhem — that won Sledge the opportunity to upgrade his abilities through combination. His partner, Throttler, is a vile little creature every bit as mean as Sledge.
- Sledge with Throttler (Commander, 2010)
- Sledge transforms into a rockwheel trencher construction vehicle with a large buzz saw at the front of the vehicle while a bulldozer type blades underneath. Throttler, in his drill mode, can be plugged onto the end of the shovel arm for "Attack mode". Sledge's bigger head is built into his normal head and the transformation involves turning his head round, opening to panels that reveal the new face, and conceal the previous one. As with the other Power Core Combiners Mini-Cons, Throttler can turn into armour.
- Due to the ambiguous continuity of the Power Core Combiners series, it's possible that Power Core Combiner Sledge is the same character as Generation 1 Sledge.
