Horri-Bull

Horri-Bull is a Decepticon warrior from Marvel's Transformers universe, operating in the high-stakes conflicts alongside major figures such as Scorponok and Shockwave. A Headmaster-era combatant, he represents the brutal Decepticon muscle introduced during the franchise's expansive 1988 roster.

Charging out of the Copper Age in 1988, Horri-Bull made his debut in The Transformers #49 under the hands of writer Bob Budiansky and artist José Delbo — two of the defining creative voices of Marvel's landmark Transformers run. This Decepticon presence has kept formidable company over the years, sharing pages with titans like Optimus Prime, Scorponok, and Shockwave, which tells you something about the high-stakes corners of the Transformers universe he inhabits. With appearances stretching across nearly four decades into 2025 — including the celebratory Regeneration One 100-Page Spectacular — Horri-Bull has proven surprisingly durable for a character with a relatively modest catalog footprint. For collectors chasing the deeper cuts of Marvel's Transformers mythology, he's exactly the kind of find that makes the hunt worthwhile.
