Popeye is the main protagonist of the Popeye franchise, a sailor character created in 1929 by Elzie Crisler Segar for his Thimble Theatre comic strip (subsequently renamed after Popeye himself). His strength varies among his portrayals: as per the original comics, he is super-humanly strong and can lift huge objects, while in later adaptations, he is not quite as mighty until he gains a boost in strength by eating spinach.
