Doubleheader

Debuting in the pages of Marvel's The Transformers #61 in 1989 — courtesy of the legendary creative team of Simon Furman and Geoff Senior — Doubleheader stepped into one of the most turbulent and ambitious stretches of the Transformers saga, sharing a universe with titans like Megatron, Unicron, and Starscream. With appearances collected in the Transformers Compendium, this is a character whose footprint in the catalog is small but whose debut pedigree is undeniable. For dedicated completists and fans of the Copper Age Marvel run, Doubleheader represents exactly the kind of deep-cut discovery that makes hunting through back issues so rewarding.
