Not sure which one between Ron or Harry would win, but Ron would definitely be a serious threat to contend with.
Hermione gets disqualified quickly because let’s remember that bit of brilliance in Order of the Phoenix:
Hermione (plus Harry and Neville) VS Dolohov (plus random DE) Dolohov and Random DE arrives in the room in which Hermione, Harry and Neville have stopped
Random DE blasts the three of them into a shelf: this takes Neville out of a while, makes Harry dizzy, but only gets Hermione covered in books
Dolohov screams to help his DE pals locate Harry
Hermione casts Silencio on Dolohov
Random DE pushes Dolohov out of his way
Harry casts Petrificus Totalus on Random DE
Random DE is K.O..
(((And here comes the dumb…)))
Hermione tries to congratulate Harry about his spell, mid-fight, while there’s still a threat casually hanging around
Dolohov, being smart, throws a nonverbal curse at Hermione while she’s distracting HERSELF AND HARRY
Hermione is K.O. FOR THE REMAINDER OF THE WHOLE BATTLE.
Yeah, Hermione is definitely getting her backside kicked, and hard.
Now, Ron, however…
Ron has a very good history in battle. Most wouldn’t realize but he is scary competent… off-screen.
Because God forbid we’re allowed to see Ron succeed at something, most of Ron’s biggest wins in the series happen out of our sight. Really, he’s not making stuff up when he feels overshadowed: his own author won’t give him the limelight!
Okay, so, that movie scene?
Yeah, THAT one!! *seethes*
Wanna know a secret?
Not only did that scene not exist in the books, but there’s a scene that is the exact opposite of this one!!
“That was really, really good, Harry,” said Hermione, when finally it was just her, Harry, and Ron left. “Yeah, it was!” said Ron enthusiastically, as they slipped out of the door and watched it melt back into stone behind them. “Did you see me disarm Hermione, Harry?” “Only once,” said Hermione, stung. “I got you loads more than you got me —” “I did not only get you once, I got you at least three times —” “Well, if you’re counting the one where you tripped over your own feet and knocked the wand out of my hand —” They argued all the way back to the common room, but Harry was not listening to them. He had one eye on the Marauder’s Map, but he was also thinking of how Cho had said he made her nervous… - Harry Potter and the Order of the Phoenix, Chapter 18
See? See that? See how that is the absolute contrary to what was filmed?
(Excuse me for a second. I just feel the need to rant intensely about the whole thing.)
“Did you see me disarm Hermione, Harry?”
Why, isn’t this interesting? Ron overpowered Hermione! Something we’re never shown in the book obviously, but at the very least there’s this conversation! Putting both Ron and Hermione as having similar talent, as being equals! (Though the fight of the DoM is quickly going to show us that Hermione should never be put on a battlefield.) And look how proud Ron is of himself! Since he knows (and loves) how clever Hermione is, besting her reassures him and makes him believe in himself. I one-upped the cleverest girl of the school, maybe I’m not so useless after all! (Consider also that Ron is still being bullied by the entire House of Slytherin at this point.)
“Only once,” said Hermione, stung.
… Geez, Hermione, you’ve got ALL those amazingly good grades. Can’t you, I dunno, let Ron have something? One little success of his own? Especially since he could really use the confidence boost, what with the Slytherins and all?
“I got you loads more than you got me —”
Take notes, fellas. It’s not only men who need to have “who’s got the biggest” contests.
“I did not only get you once, I got you at least three times —”
… Okay so not only did Hermione NOT let Ron have this victory, but she even downplayed it. Why is that girl described as “non-judgemental” and “fair-minded” again?
“Well, if you’re counting the one where you tripped over your own feet and knocked the wand out of my hand —”
And now she’s ridiculing him. Just because her pride won’t allow her to encourage Ron. (Meanwhile? There are several instances of Ron complimenting her throughout the seven books - yes, Order of the Phoenix included.)
Geez, Hermione. I’m glad Ron is happy but seriously, why he fell for you, I have no clue. Oh right… wish-fulfillment, wasn’t it? ;)
Conclusion: the Harry Potter movies are as much of fanfiction as Cursed Child is and were more focused on fueling Steve Kloves’ wet dreams than on depicting the actual content of the books.
Now that the “I’ll-reincarnate-myself-as-a-dog-to-use-Steve-Kloves-as-my-personal-lampost” rant is over, let me show you another way Ron is a badass…
Well, first, he’s a strategist, a chess player. So he can be more creative than “let’s rush in and solve the mess later” Harry is.
At the fight of the Department of Mysteries, Ron gets cursed. And Luna tells us what happened: Ginny got trapped by a Death Eater, Luna blasted Pluto in his face (it makes sense in context) and inadvertently broke Ginny’s ankle with the debris, while Ron was fighting “them” and got cursed.
As in, multiple people.
Luna mentioned that four Death Eaters had followed their group. With one DE she took down, which leaves three Death Eaters for Ron to fight off. AND HE DOES, THE ABSOLUTE MADMAN (Honestly, massive respect, because he didn’t just fight three adult wizards, he survived a confrontation against three trained assassins)
And in Deathly Hallows? Well, first, Ron is partnered with Tonks, and guess who ends up chasing them: Bellatrix Lestrange herself!
Tonks has nothing but glowing praise to give Ron, stating that he saved her life with a Stupefy that a Death Eater took full in the face… mid-flight!
And as if that’s not enough, after he leaves the Horcrux Hunt and attempts to come back, Ron gets delayed by Snatchers who take his wand away. He’s one, unarmed, against five prime hunters… But he gets the upper hand on them by pretending he’s someone else, and while they’re distracted, he frees himself from the one who was keeping him captive, gets his wand back, steals one of their wands because Ronald Weasley is just that badass, and Disapparates.
Yeah… I wouldn’t say that Ron is going down easy. *snickers*
