Was Harry Potter an innately powerful/skillful Wizard in any way, based on canon?
It seems that whenever Harry Potter performed some unusually potent bit of magic (potent as far as require raw power AND/OR skill), most of the time we find that it wasn’t innately Harry’s skill, but a combination of:
some extraneous magic forces/rules/powers
circumstance
great reaction time (which is obviously extraordinary from his Quidditch playing; and is likely a larger factor in his dueling than the strength of his magic)
general smartness
or (the part that Harry’s detractors, including Voldemort missed) Harry’s strength of character/personality
The only two counter-examples I can think of which show him as having extraordinary or at least obviously above average magical abilities are:
His skill at flying brooms - while a part of it is pure physical skill, at least part is magical.
His (corporeal) Patronus charm
As far as examples of his unusual feats being due to reasons listed above:
Obviously, surviving Avada Kedavra as an infant - due to Lily’s sacrifice
Parselmouth talent - proxied via Voldemort’s piece of soul.
Ability to see the Sorcerer’s Stone in the Mirror of Erised - due to purity of his character, nothing magical.
Obvious lack of talent at potion making throughout all of the books (sans cheating in HBP)
His win over the Basilisk - due to Hermione’s research, character traits, and as a consequence of the last one, getting Fawkes and Gryffindor’s Sword’s help.
Just to be clear, before someone flames me - what he did was obviously super extraordinary, BUT IMHO he would have achieved the same result if he was turned into a Squib for the duration of Chamber of Secrets fight.
TriWizard Tournament entry - wasn’t him, it was Barty Crouch
TriWizard Tournament second challenge - a combination of character and outside help (someone told him about Gillyweed)
TriWizard Tournament third challenge - Mostly, Barty Crouch’s cheating
Note that I’m omitting the first challenge, since that one was the aforementioned Broom flying skills.
His survival in the cemetery after Voldemort’s return - again, a combination of superior strength of character and super powerful wandlore magic that had nothing to do with his skill as a Wizard.
The whole “last Horcrux” thing when surviving the second Avada Kedavra from Voldemort
His ownership of the Elder Wand in the very last duel with Voldemort.
So, to paraphrase my original question, was there any canon/JKR evidence that Harry was anything but a completely average/mediocre wizard in any way, shape, or form if you take into account only his own magical abilities and skills?
