Although the titular Harry Potter is obviously the biggest hero in the Harry Potter franchise, there are many characters who have proven their bravery, kindness, compassion, and overall worth throughout the story. And it should come as no surprise that some of the most benevolent characters in the series were also members of Dumbledore's Army.
Also known as the DA, Dumbledore's Army was a group of proactive students who were preparing for the upcoming battle against Voldemort. But, despite the fact that most of them were already the most badass kids in school, which members of the group were slightly more heroic than others?
It says a lot about how heroic Dumbledore's Army really is that Seamus Finnigan is arguably the least heroic major player in the group.
Seamus ultimately did a lot to battle against Lord Voldemort and defend Hogwarts, however, the fact that he did question Harry's truthfulness and did suspect that he was lying about Voldemort's return for a time makes him one of the lesser members of the DA when it comes to being a straight good guy.
Given that Dean Thomas has a family full of muggles, it's not as if taking up arms against Voldemort was much of an option for the half-blood wizard.
However, Dean has always been an incredibly solid and reliable guy, a great friend, and is honestly the kind of person who would likely have fought against the tyranny of Voldy either way. It's certainly no surprise that he signed up for Dumbledore's Army.
Although teenage relationships aren't built to last, Cedric Diggory's death gave Cho a very real connection to the fight against Voldemort and the Death Eaters.
Joining up with the DA was a logical conclusion to Cho's experiences at Hogwarts, but what distinguishes Cho among many others is that she went out of her way to fight against the baddies. She had already graduated from Hogwarts by the time that the Battle of Hogwarts occurred, but she returned specifically to defend the school.
Given that Hermione and Ron were pretty much written in the stars from day one, it's no shock that most fans didn't warm up to Lavender Brown (although to be fair, her personality and overall behavior wasn't winning many people over either).
However, Lavender's commitment to the DA can't be questioned, because she literally gave her life in the Battle of Hogwarts in defense of the school and it's students.
When the rubber met the road, most of the students who joined Dumbledore's Army proved their mettle and raised their wands to fight against the evil witches and wizards that were attempting total world domination.
But when it comes to someone like George, he's a bit different because he was continually fighting against bad guys long before it became a life or death proposition. He stood up against Umbridge, he lost an ear helping Harry, and he returned to Hogwarts to fight.
Neville has not only proven himself a worthy Gryffindor who destroyed a Horcrux and kept the fight against Voldemort alive at Hogwarts, but he has also done more than the vast majority of DA members have .
Considering that Fred and George were two peas in a pod before Fred's tragic untimely death, it comes as no surprise that all of the bravery that George displayed had been displayed by Fred as well.
Of course, if he'd had the choice he would have survived, but again, given that Fred is one of the few DA members to actually give their lives to the cause, he's pretty exceptionally heroic.
As a co-founder of Dumbledore's Army, Ron both proved himself as a member of the DA and as a hero in his own right. While it always had to be Harry who would defeat Voldemort for good, he couldn't have done it without the help of Ron and Hermione.
Obviously, Ron's only major misstep in his journey saving wizardkind was abandoning Harry and Hermione during the search for the Horcruxes.
Clearly Hermione and Ron have been Harry's ride-or-dies pretty much since the moment they met at Hogwarts, but again, it seems like Hermione just held together the golden trio a bit better than Ron did.
Hermione went as far as erasing her existence from the memories of her parents for the sake of the mission, and not once did she even think about abandoning Harry, even when her loyalty put her in mortal danger.
Of course, who else could be the most heroic member of Dumbledore's Army but the literal hero of the entire story and the wizarding world at large?
Harry never really had the option of not being the hero destined to save the world from the dictatorship of Lord Voldemort, but even if he didn't have to do it, he likely would have volunteered to do so in the first place.
