In the world of Harry Potter and friends, the Patronus Charm, which is conjured by saying the incantation Expecto Patronum, is one of the most powerful defensive spells that any wizard or witch can cast. When this extremely difficult spell is cast, it evokes a positive energy force, called a Patronus, which protects the caster against creatures like Dementors and Lethifolds. Not every magical being has one, and it has been said that only powerful witches and wizards are able to cast the spell. 

Patronuses come in one of two forms: corporeal, which have a particular shape and form, and incorporeal, which do not. Most wizards have one or the other, but there are some, like Professor Lupin, who are able to choose which form their Patronus will take. Lupin dislikes having a wolf as a Patronus, so he often prefers to summon a non-corporeal version. 

A witch or wizard's Patronus is usually some kind of animal, but in this quiz, it is going to be one of Marvel's Avengers. Would you like to know which one of them is going to come out of your wand when you shout "Expecto Patronum"? Well, if you would like to find out as much as we would, then you will have to take this quiz!
