Superman succeeded in establishing a vast, detailed world with a rich history that surrounds aliens and metahumans. It even introduced several iconic comic book characters with roots far beyond Superman’s, including the Green Lantern, Hawkgirl, Mr. Terrific, Metamorpho, and the Engineer. This was all done on planet Earth.

James Gunn's recent comments about Supergirl's age and her knowledge of Krypton have already created a plot hole for the upcoming Supergirl movie.

While it may seem like Henry Cavill's Superman got the short end of the stick after the DC Universe reboot, one character had it worse.
