Consider more mature / adult oriented series, and literature. Marvel and DC will always appeal to the status quo.

Try Image comics. Spawn started adult and things go on from there. Tons of shit goes down including the end and rebirth of the world. Savage Dragon has run on so long that characters who weren’t even born when the series started are grown adults with kids, and the main character is literally dead (not comic book dead, just dead and gone).

In books there’s stuff like Soon I Will Be Invincible, Murs Lafferty’s Playing For Keeps, Paul Tobin’s Prepare to Die (a somewhat vulgar example at times but also hilarious, the hero’s power is to take a year off someone’s life by punching them).

Also good is Marion G. Harmon’s Wearing the Cape series, wherein time passes, crazy shit goes down, heroes get hurt, die, retire, etc. Starts with the main character at 17 I think, but as of the current book she’s well into her 20s and married. This one is a mix of junior and adult capes, where superheroes are state and government sponsored as a legal requirement.
