Okay but seriously, I have read a few in which Harry's a demigod, but like they're ALWAYS discontinued. Does anyone know some which are ongoing and have been updated recently? (if anyone is actually reading this which I don't believe)

Demigod Harry

What I personally think is that Harry is a son of Aphrodite IF we choose to believe Dumbledore's sayings (read bullshit). Like he said Harry had the power to LOVE. This means that he is acknowledging that love is a powerful force, which will help defeat Voldy (which I still don't believe but love helps you be determined- sooo... Also if he was a son of Aphrodite then that secret power would make sense)

So Harry as a son of Aphrodite would be a pretty interesting topic to write upon. Also, that would give so much respect to Aphrodite cabin if you went into the reasons they were like that. I still believe that they should be able to fight. Because Chiron would make sure they could fight.

Demigods as magic resistant

Another thing, as the demigods are seemingly magic resistant- which makes absolutely no sense. it was like Rick Riordan put it there to make it seem like the demigods are the best. They have to be beaten somehow, or else that's just making them mary stues and gary stus. it's annoying. And secondly, a daughter of Hecate using magic CAN affect demigods. So not magic resistant. Circe turned Percy into a guinea pig- not magic resistant.

If we go with the fact that wizards are long long legacies of Hecate, then fine, that's perfect. Then you don't even need to twist the facts that demigods are magic resistant. There'll be no need absolutely for it to seem like you don't like the concept.

Personally, I think that it'd be a very long battle between demigods and wizards. Contrary to popular belief, wizards are powerful too, they aren't weak or whatever. 

Bashing- 

PLEASE I'M BEGGING YOU, PLEASE STOP WITH THE UNNECESSARY BASHING. IF I SEE IT ONE MORE TIME I'M GOING TO SPLIT MY SKULL IN HALF AND DROWN IN MILK MIXED WITH HOLY WATER. 

If the bashing is in the perspective of someone else, who has their own opinions then okay.

Like Seamus (no bashing him he's a chaotic guy who believed the ministry for the most part- he's amazing)
He believed that Harry was a liar. So whenever Harry got angry, in Seamus' perspective Harry wouldn't be a very nice guy. Just a liar.

But if we take order of the phoenix from Harry's pov, then Harry will not be a liar. 

To tweak something, you can take Harry's anger, make him more stressed, which causes him to get angrier. But YOU HAVE TO GIVE HIM THE EXTRA STRESS for it to make sense.

Cliches

UMM... NO, I CAN'T TAKE SO MANY ANYMORE. I'M GOING TO HAVE TO BURY A HOLE SIX FEET UNDER AND JUMP FROM MOUNT OLYMPUS. 

Percy as Voldemort's grandson makes much less sense that I want to cry. Of course, if it was executed properly as if Percy turned out to be a squib grandson- (but with his Poseidon powers) then that's cool. Voldy would hate Percy, and I don't understand why Harry would hate Percy without even meeting the guy.
AS A KID, HARRY WAS JUDGED WITHOUT THE DURSLEY'S KNOWING HIM. WHY THE FUCK WOULD HE JUDGE PERCY THE SAME WAY????? HARRY WAS JUDGED BY THEM DUE TO HIS MOTHER BEING LILY AND HIS FATHER BEING JAMES, SO WHY WOULD HE JUDGE PERCY FOR BEING A GRANDSON OF VOLDEMORT??????
In my opinion, Harry and Percy would have a rocky start, with both of them awkward around each other. Soon, they'd realise they can get along well- and BOOM. THEY GET ALONG LIKE A HOUSE ON FIRE. 
LOT'S OF BROTHERLY FEELS- *chefs kiss*- PERCY AS A BIG BROTHER - YUP

Demigods having magic somehow????
Wait hold up WHAT- how the hell did that happen. their parents are gods of a certain domain, they can't do magic. if it's a child of Hecate- YES, YUP TOTALLY- but a normal demigod, no...

Nico goes to Grimmauld place- makes sense. But it's been done so many times, I think you should get inventive about it. Don't ask me, I already have some ideas in my plot shop- if you do want some ideas- kindly go there, credit me, follow the rules and tada- you can write it.

PART 2 COMING SOON I CAN'T WRITE TOO MUCH IN ONE GO SORRY
