5. Scarlet Witch (2015)
Aside from one very brief, forgettable solo run in the early nineties, Scarlet Witch did not receive a significant solo comic until James Robinson decided to take on the character in 2015. The story has Wanda realise that Witchcraft is somehow broken, and sets off on a globe-trotting journey to fix it, accompanied by the ghost of her mentor, Agatha Harkness.
In between battles with monsters and warlocks, the series also explored the longterm effects of Wanda's powers in ways that had never been deeply discussed before. It also peeks into her sometimes complicated relationship with her family.
An issue in which Wanda visits a therapist has her discussing her feelings about the magical origins of her children, the Young Avengers Wiccan and Speed. Another, set during Marvel's Civil War II event, has Scarlet Witch do battle with her twin brother, Quicksilver, after she refuses to become involved in the drama between Iron Man and Captain Marvel.
Part adventure story, part character study, this book is a must read for anyone seeking a deeper understanding of who Wanda Maximoff is in preparation for WandaVision.
