Starscream (Transformers) 5

Quite simply the most fascinating cartoon villain of the 1980s. Unlike one-dimensional simpleton thugs like the Cobra Emperor (genes of Napoleon? Hardly!), Starscream was complex, nasty, and backstabbing. He was an understudy of Machiavelli, sounded like Brian Johnson of AC/DC, and could change into an F-15. What more is there to want?
