Summary: What if Harry wasn't the 'Boy-Who-Lived'? What if James and Lily were still alive? What if Harry had a brother who was two months older than him and wasn't Lily's son? What if Harry was never placed with the Dursleys, but his brother was instead? What if all of these 'what ifs' were true?

Disclaimer: Harry Potter belongs to J.K. Rowling and Twilight belongs to Stephanie Myer. Neither story belongs to me…obviously. I own Tobias and if I did own the books they would be very different from what they are. This is my first time doing a Harry Potter/Twilight cross and reviews of any kind are appreciated.

Prologue: Tobias William Potter-Snape

My life has always been boring and unpleasant, but that all changed when I turned eleven. On my eleventh birthday I met a half giant named Rubius Hagrid. I also found out I was a wizard and learned about Hogwarts School of Witchcraft and Wizardry. When school started I found out that my parents were two men, one of them would be my Potions Professor, and that I had a half-brother named Harry Potter who was two months younger than me. I was made Seeker on the Slytherin House Quidditch team and became the youngest Seeker in a century. The Defense Against the Dark Arts teacher, who was possessed by a piece of the Dark Lords soul, tried to kill me.

During the summer I was removed from my 'relatives' care by my two fathers. It turned out that I wasn't really related to the people who raised me and that my parents thought I was dead until last year when I started school. In school the Chamber of Secrets was opened and I was suspected of being the Heir of Slytherin. Students were being paralyzed by the creature inside the chamber and the other students blamed me for it. One of my friends Hermione Granger, a muggle born and a Gryffindor, was one of the students who was paralyzed by the creature. I discovered that I was a Parclemouth that year and that the heir of Slytherin was Tom Marvolo Riddle, also known as Lord Voldemort. The creature inside the chamber was a Basilisk and I killed it with Gryffindors sword and destroyed Tom Riddle's diary with one of the Basilisks' fangs.

In third year Sirius Black broke out of Azkaban. Dementors, the guards of the wizard prison Azkaban, were stationed around the grounds of Hogwarts because Sirius was supposedly after someone at Hogwarts. Everybody in the Wizarding World thought Sirius was after me, but my parents and Harry's mother Lily didn't believe that. It turned out that Sirius was after a man named Peter Pettigrew who was a rat Animagus. Sirius was also my godfather and was framed for the murder of Peter Pettigrew and thirteen muggles. The Defense Against the Dark Arts teacher, Remus Lupin, turned out to be a werewolf and one of my parents best friends.

In fourth year Hogwarts held the first Tri Wizard Tournament in fifty years. Somehow my name got placed in the Goblet of Fire and I was chosen as the fourth Champion in the tournament and the second from Hogwarts. I out flew a Hungarian Horntail dragon on a broom in the first task and rescued Fleur Delacours younger sister as well as Harry from the Black Lake in the second task. Harry developed a crush on Viktor Crum, a star Quidditch Seeker and Durmstrangs Champion. I really wasn't very surprised when Harry went to the Yule Ball with Viktor. All three schools had been surprised and shocked at the two boys but I couldn't keep the grin off of my face when Pansy Parkinson, one of my best friends and a pureblood Slytherin, and Hermione danced with each other. The third task was a maze and the winner was the one who made it to the Tri Wizard cup in the middle of the maze. Cedric Diggory and I got to the center of the maze at the same time so we both grabbed the cup at the same time. Cedric died that night and the Dark Lord was brought back to life. Nobody believed me when I told them and the thought I had killed Cedric to win the Tournament and I was thrown in Azkaban. My name is Tobias William Potter-Snape and this is where my story begins.
