inspiring. as in:
moves a star without the worry of breaking it and causing a star level explosion near earth.
being told and i SHIT YOU NOT "that metal moves stars so you can break it" and breaks it without effort all on one page.
make him relatable then have him being OP for no reason, making it harder to believe that an all powerful being has some trouble.
for all i care, superman was the first gary stu before the star trek mary sue later on. you call him inspiring yet we understand why batman might have to kill him whenever.
superman isn't inspiring, or relatable, he's a gary stu.
