Make A Wish is a Harry Potter fic written by Rorschach's Blot.After the events of Order of the Phoenix, Harry decides that he doesn't particularly want to simply go off and die in a final confrontation with Voldemort, at least not without having a chance to see a bit of the world first. What follows is a vacation that spans the summer (and a good part of the fic), and takes Harry, under the alias Mr. Black, through several countries, adventures, and more than a few dead Death Eaters.It also has a sequel, The Hunt For Harry Potter, by the same author, along with numerous fan-made omakes and sequels that can be found on his Yahoo Group or the fanfiction.net community Black Ink.
Contrived Coincidence: This happens a lot. It is implied that these coincidences are actually planned out by the members of a family that can see the future, led by the Diagon Alley shopkeeper that sold Harry his travel hardware. This is better seen with the wizard Wormtail buys the Portkeys from: he always sends them to where Mr Black is going to be or nearby, but in such a way that it is lethal (or almost lethal) for the Death Eaters.
It's also possible that the coincidences happen because of Harry's insane luck. On one occasion he wanders through a casino, and places a single bet. A bet that wins so big, the casino investigates it, turning up a cheat in the process.
Dark Is Not Evil: Played with. Mr. Black is believed to have been a Dark Lord who destroyed civilizations in a previous life and is now The Atoner. That doesn't stop him from scaring pretty much everyone.
Later in the story, it is believed that one of those civilizations was Atlantis. Since, if they were willing to exile a wizard for being "too weak", it worried everyone to think what they would do to non-Purebloods... and Mr. Black's hatred towards Blood Puristsis verywell-known.
The Dreaded: Mr. Black. Death Eaters would rather go to Azkaban than risk the chance that Mr. Black might kill them in a horribly gruesome way
I Never Said It Was Poison: Accidentally. When he arrives to Marseilles and gets attacked by a Muggle serial killer (armed with a magical knife), Harry is interrogated by one Auror, who calls him Mr Black at the end of the interview. Harry jokes about how fast they arrived (not knowing they were following him) and then tells the Auror's healer that the interviewer's technique was so good he does not even remember giving him his name. The Aurors take these quite seriously.
Improbable Weapon User: when Harry gets attacked by Dementors at Diagon Alley after he returns, instead of using his Patronus charm (which would give up his identity), he just pulls out the "Mr Black" chocolate frog card the Twins made, which sprouts hot chocolate when tapped with a wand. Hilarity Ensues.
Incredibly Lame Pun: When Harry is at Paris, trying to enjoy the city's monuments and museums but having to deal with the long queues, he cannot help but think that, instead of "The City of Lights", Paris should be called "The City of Lines".
Loads and Loads of Characters: Subverted in Mr. Black's entourage. While the Professor, Henchgirl, and the Doctor all play major supporting roles, the Architect and the Mechanic have very small parts, and the Tailor and the Leather Worker are never even seen, while many characters just get a name and one scene and maybe a callback or omake later in the story.
Ninja Pirate Zombie Robot: Mr. Black becomes a hybrid of vampire and werewolf, plus the fact that his blood is mixed with basilisk venom and phoenix tears, among other things.
Not Enough to Bury: Death Eaters and other Blood Purists get hit with this. Hard. And often. In Germany, the coroner had trouble telling the pieces apart after Black gives his Russian battle magic a try, a Death Eater attack team was ran over by a train and damaged beyond recognition, the Lestranges had to be mopped up and picked clean from the insides of a vending machine, another Death Eater team was Eaten Alive by Australia'sdeadlywildlife, and let's not forget the bandits that were eaten by a nundu...
Read the Freaking Manual: there are several instances of Harry (or someone else) getting instructions to make something work. When he returns to England, Harry is less than pleased to be told that the reason he got in so much trouble was because he didn't read the instruction manual for the SEP Field Generator.
Rule of Cool: Why did Henchgirl enchant her zeppelin to have a rolling bank of clouds surrounding it at all times? Because it's cool.
Sure, Let's Go with That: a French Auror wizard that can transform into a poodle tells his female partner that the most dangerous people try to look like they are the harmless. The witch asks him if that is why he had her groom him and put a bow around his neck. He says yes this way.
The Cassandra: the shopkeeper at the beginning reveals to Harry that he and many in his very extended family inherited Cassandra's curse, which is what prompts them to do what they can to help the world.
Wronski Feint: Harry takes part of a broom race that goes through a dragon sanctuary, and, just his luck, managed to get nearly every dragon hunting him. He tries to use the sunlight to blind them, but ultimately shakes them off and wins the race with a textbook perfect Wronski Feint against the ground, saving the other racers in the process.
