His strength of character. Just like Batman in the DCU, Steve Rogers is respected by everyone, despite: Not being the strongest… Not being a god… Having a fundamental disagreement… Or being with the king of one of the most advanced and rich nations on the planet… He’s the first to protect others from any danger. He’s willing to sacrifice anything for his best friend. Characters that are way more powerful than him, heave a sigh of relief when he arrives to fight . He’s always first in line, no matter who’s in front of him, no matter who’s behind him. Aaaaaaand… Beasts take orders from him; gods fight alongside him; geniuses admire him; kings respect him; enemies fear him. That’s why he stands out. I think this image perfectly sums up who he is. “I can do this all day”. Yup. He can and he will.
