Shuri is so great because while she is ridiculously smart and is the head scientist of the Wakandan Design Group, she still acts like a teenager who enjoys music, jokes and messing with her big brother. I love the scenes with her and T’Challa. They feel like proper siblings but T’Challa still listens to her judgement when it comes to the technology she’s created.
I like how Shuri is a character that has many sides and responsibilities. She’s Princess of Wakanda, meaning she has certain responsibilities and must act a certain way when she’s doing her royal duties. She’s a scientist and engineer, making much of Wakanda’s modern technology. She’s a warrior, prepared to fight alongside her brother for the good of Wakanda. But then she is still a young woman with a sense of humour and her own ideas about what’s right and good.
I also love that in the MCU all characters just accept how ridiculously smart this young black woman is and no one underestimates her. Or if they do, they end up regretting it.
