Metafictional Cube
A 13 year old boy named Alex is bullied at school and is unable to find friends. To cope with his bad situation, Alex turns to many works of fiction, such as cartoons, movies, books and video games. He explores many detailed, fictional worlds and in his dreams goes on adventures with his favorite heroes.
After an especially bad day at school, Alex sees a meteorite fall down in a park near his home. He runs towards the crater and sees a bright, green cube. Curious, he touches the object, finding it very cold to the touch.
Immediately as he does so, one of the walls of the cube goes dark. At the same moment, one of Alex's favorite heroes appears nearby: Harry Potter. Harry was taken from right after Dumbledore died in the books.
Unfortunately, because in the books Harry is a Horcrux, he is inherently tied to the Dark Lord Voldemort, who has been therefore brought to the real world as well.
Needless to say, Voldemort is not in the least amused by such an event. He attempts to murder Alex and Harry, but finds out that for some reason he is unable to intentionally attack Alex. Furious and confused, Voldemort Apparates away, not having enough information to act properly.
Harry and Alex talk, Alex revealing that Harry is a character from a book and that he has been summoned accidentally.
Quite naturally, Harry is freaked out by all this and at first refuses to believe it. Eventually though, he is forced to accept the reality (it takes some time, but it does happen). Harry reads the remaining books, learning of his would-be future. Meanwhile Alex discovers that not only the cube is for some reason following him around but has become invisible to everyone except him and Harry (and presumably Voldemort).
Riddle figures out that there is no magic in this world and he eventually discovers the Potter books and movies. He also forms a theory as to why he is unable to attack Alex: it is because Alex has summoned him and summons generally obey their summoner. This is a worrying thought to Voldemort, so he decides to avoid the young boy.
Alex's parents discover Harry's presence and while at first they do not believe that he is who he claims he is, his magic convinces them.
And then the second wall of the cube goes dark and another character appears: Jedi Master Yoda. Unfortunately, the Force connects living beings across the universe and a most powerful Dark Lord of the Sith, Darth Sidious has been brought along for the ride.
That's as far as I got with this. You could literally have any fictional character you can think of appear in the real world. Villains, heroes, anyone. Pokemon, Naruto, Avengers, Transformers, Teenage Mutant Ninja Turtles, ANYONE.
The idea is that the only way for them to go home is to either destroy the cube or if Alex dies. However, they don't know this.
The title refers to the fact that even though Alex sees his summons as fictional characters, he is still fictional to us.
