Optimus Prime

Few characters carry the weight of a name like Optimus Prime, and this Marvel incarnation made his catalog debut in the pages of G.I. Joe, a Real American Hero #140 in 1993 — a Copper/Modern Age entry point that dropped him into one of Marvel's most action-packed corners of the universe. Across roughly three decades of publication, he's appeared alongside heavy hitters like Megatron, Grimlock, Starscream, Kup, and Hot Rod, with his strongest presence felt in Transformers: Generation 2 and the Transformers Compendium. It's a lean but meaningful footprint in the Marvel catalog — sixteen appearances that trace a character whose name alone signals something iconic, making every issue he graces worth a second look for any serious collector of the era.
