Line

Debuting in the climactic pages of Marvel's The Transformers #66 in 1990 — right in the thick of the Copper Age, when Simon Furman and Geoff Senior were steering the series toward some of its most ambitious storytelling — Line is a character who entered the mythology at one of its most dramatic moments, sharing the page with titans like Optimus Prime, Galvatron, and the world-devouring Unicron himself. With appearances catalogued across an impressive span stretching into 2025, including Transformers Compendium, Line has proven to have genuine staying power in the lore. Rare in the catalog but persistent across decades, this is exactly the kind of deep-cut figure that rewards the dedicated collector willing to dig into the corners of Marvel's Transformers universe.
