A bad day is the whole test
Heroes are easy to tell apart when something enormous is happening. They are much more interesting on a slow, irritating weekday. This Marvel character test is a short personality quiz that matches you with one of six heroes by looking at small stakes: a deadline you are behind on, a family gathering, a neighbor who wants a favor on your only free day. How you handle those says more about you than any imaginary superpower would.
Six heroes with the suits off
Take away the powers and the costumes, and what is left is six very different ways of coping. Iron Man can't leave a problem alone and comments on it the whole time. Captain America does the right thing steadily, including when it is unpopular. Thor is big-hearted and loud, and fully expects the day to go his way. Black Widow notices everything and gives away very little. Spider-Man is the eager helper who has agreed to too much and is joking through it. Hulk is the gentle thinker who holds things in for longer than is good for him.
Each result page describes what that hero is good at, where they tend to trip, and which of the other five they work best with.
What you need before you start
Very little. The quiz is 12 questions long and takes about two minutes. It is free, it runs in your browser, and there is no sign-up or account. You don't need to have seen the films or read the comics, because no question mentions them or names a hero. It is also spoiler-free: the result pages talk about personality and leave the plots alone.
Reading your result as a team
Results get more useful once a few people you know have theirs. A group with no Spider-Man should ask who has been doing all the favors.
