Superman is a globally recognised hero. He's famous as HELL. He's a symbol. People probably see the cape first, the humble person beneath it second.

I want to see the League forming and Superman meeting other heroes that aren't Batman or Wonder Woman, and have them be very, very intimidated/awed/freaking out over him. Superman died when the world was more fearful than respectful - I'd to see him reacting to all the love/awe directed his way. Especially from other respected superheroes. Fill can be gen/any (I am partial to superbat, though), and humor/fluffy/hurtcomfort/or whatever.

Bonus:
- Diana is smirky-amused by the younger heroes falling over themselves in front of Clark
- Flustered!Clark
- Barry freaks out the most
- Team eventually becomes friends with Clark :')
