Harry Potter was the first known wizard that "Ruled Death" by putting the Elder Wand, the Invisibility Cloak, and the Resurrection Stone under his power. Let's learn about his life after successfully killing Voldemort.

 Harry marries Ginny Weasley, and has three children- 

James Sirius, after his Godfather and Father, Albus Snape, after two, close former headmasters of Hogwarts, and Lily Luna, after his mother and friend from Hogwarts. When Harry is 36, Ginny 35, Albus is on his first year to Hogwarts. Lily wont start school until I  believe 4 years, James has been for I believe 3 years.

 Harry becomes an Auror, like he wanted to, and also becomes the youngest Auror Head at 26. He occasionally comes to Hogwarts to give lessons about Defense Against the Dark Arts.

 Harry is Teddy Lupin's godfather. Ron and Harry are related (just like what we all wanted) through Ginny, and it seems like Harry didn't have to deal with someone as evil as Voldemort again.
