Sentry is the closest and farthest from being Superman. I loathed the character as a uninspired Supes knock off, but quickly found a fondness for him as his character was fleshed out over time. He has as someone else out it evolved in powers and how to use them. As a character he was always was a total wreck in personality which is a strange appeal as one day he is the good guy, and the next the villain. I liked that aspect of him.
Hyperion is a knock off period. The most fleshed out version of Hyperion is the. Supreme Power comic line Hyperion who is not only really interesting, but very brutal with his powers. Anyway he is a super man clone in that backstory through and through.
Blue Marvel, heard of him and that's it.
Blue Marvel reminds me of Icon for some reason...... Icon was Milestones Superman analogue. He also reminds me of Solar and Dr. Manhattan in his origin. Blue Marvel as Delta stated earlier should be Marvels Superman. I like the character a lot.
Sentry was a deconstructed Superman clone in his first mini, Bendis ruined that and made him silly. The Uncanny Avengers stuff was barely readable.
Hyperion is a homage, but being used beautifully by Fraction.
