No, he didn't. At least not in the original series (I own the first 20 or issues). Shockwave was 2nd to Megatron and, like the more conniving Starscream, coveted Megatron's status as leader of the Decepticons. For a while, he controlled the Decepticons after taking down the (weakened) Autobots (Transformers 4) and defeating (a still injured) Megatron in single combat (I think that was Transformers 6 or 7).Klaus said:In comics continuity, Shockwave outranked Megatron.
