You think you know your Marvel Comics Super Heroes? You probably have nothing on 4-year-old Mia Grace.
SLIDESHOW: Marvel Comics at the movies
In a viral video the young girl shares her super hero super-knowledge.
Mia's dad: What is Captain America's shield made out of?
Mia's dad: Name an infinity gem in the Infinity Gauntlet?
Mia's dad: Where does Dark Surfer trap Captain Marvel?
Mia: In the Soul Stone.
The video was uploaded by Mia Grace's dad - YouTube user DaddyDadBlog.
Although she did get some questions wrong - we're right about this - she's pretty darn adorable.
