I just got a g1 jetfire and was wondering which toy came first, g1 jetfire or robotech valkyrie? who stole who's idea?
Yep, and the same goes for a high number of G1 TFs (Hasbro borrowed/bought molds from other lines). Hell, technically, ALL the original G1 bots were acquired elsewhere, namely Takara.
Most of G1 came from licencing of diaclone & microman lines from takara. Hasbro was so succesful re-theming both lines that, takara licenced name transformers from hasbro and re-themed their line. Thus a partnership/juggernaut was born. Some early G1 toys came from other sources. Jetfire, shockwave, whirl, roadbuster, the 4 large insecticons. I remember shockwave being sold in radioshack in a different color & name at the same time he was in toy stores as shockwave. Most tf's since year 3 or 4 of G1 have been made by hasbro & takara.
Nobody "stole" anything there. (Otherwise there'd have been some huge-ass lawsuit.) Hasbro simply acquired the license for the Valkyrie from Takatoku (later Bandai).
