How do the Marvel Comics versions of Transformers characters (e.g., Optimus Prime, Megatron) differ from their G1 cartoon or IDW counterparts?

The Marvel Comics versions of characters often had more complex and sometimes darker personalities than their G1 cartoon counterparts. Optimus Prime, for instance, grappled more with the burden of leadership and moral ambiguities, even dying and being resurrected multiple times. Megatron was frequently portrayed as cunning and ruthless but also prone to fits of rage and less prone to the cartoon's often comical incompetence. Shockwave was introduced early as a cold, calculating, and highly effective leader, often usurping Megatron. These interpretations often influenced later iterations, including IDW, which further explored psychological depths, though IDW developed its own distinct continuity.
