While the cast of Transformers: Devastation are mostly based on their G1 designs from the 1984 cartoon "The Transformers", the designs of Megatron, the Stunticons, and the group's combined form Menasor are a hybrid of their G1 designs, their designs in IDW Publishing's comic adaptation of the franchise, and the Combiner Wars toy-line that was released in 2015. This is more evident by the sturdier build Megatron sports to relate to his tank alternate mode (his original alternate mode was a pistol resembling a Walther P-38), Motormaster's arms (they were mostly light grey in the cartoon with minimal details), the Stunticon Offroad once again replacing one of the group's original members Wildrider, and the design of Menasor's chest.
