Wonder Woman & Captain America Crossover Headcanon
Remember how MCU!tSteve says in First Avenger that his dad died because of mustard gas?
His dad was one of the soldiers who fought at Veld and stayed behind to make sure the village was safe, and it was Dr. Poison’s mustard gas that got him.
One of his army buddies who survived told little!Steve Rogers about the wonder woman who made it possible for them to take back Veld, and Steve grew up idolizing her.
The reason he immediately leaped at the chance to use a shield at his weapon of choice was because of the story of how his heroine used a shield to distract the German soldiers.
When he saw the shield in the midst of Stark’s weapons – a round shield at that – he leapt at the chance to be like his role model.
That springboard move he had Natasha do in Avengers? He remembered the story of how his heroine used that move during the battle for Veld.
