The core of the story of the MCU started with Iron-Man.
A genius selfish billionaire who learns the consequences of his actions and changes for the better as a result.
It had Captain America, as it's first heroic symbol.
A man who had nothing, except for a kind heart and a strong moral compass rise for the challenge to be a symbol of hope.
Then, along with Hulk and Thor as core pillars alongside Hawkeye and Black Widow formed the team of The Avenger's to take down Loki.
Though a much bigger threat was waiting.
