Chapter 1: Beginnings
A long time ago before the year 2003, there existed the year 1998. Let's go back to the time period in Hoenn; when Brendan first moved there, way before he began his Pokémon adventure.
Brendan and his older brother Thomas were in the moving van waiting for it to stop at Little Root Town.
"Hey Thomas, do you think we'll meet friends here?" asked Brendan.
"Maybe, I'm kinda hoping I'll score a girlfriend here!" replied Thomas.
Brendan had then changed his mind on making friends and decided he wanted a girlfriend.
Finally the moving van stopped, meaning that they made it to Little Root Town. Thomas and Brendan immediately hopped out of the van to get a look at their new home.
A bunch of Machokes were loading the furniture in Brendan, Thomas, and their parents' new house.
"Hey Thomas, I'm going to our neighbor's house to meet them!" said Brendan.
"Oh, okay Brendan. I'm going to Professor Birch's lab to get my first Pokémon," replied Thomas.
"That's cool; you are going to start your Pokémon adventure tomorrow! I'll miss you, bro!"
"I won't be leaving 'till tomorrow. You better head to the neighbors' house."
Brendan then went to the neighbors' house. "Hello Mrs. Birch, my mom wanted me to meet you. We are your new neighbors!" said Brendan.
"Oh, hi Brendan, I was a friend of your mother's before. I think you should go up and meet May." said Mrs. Birch.
"Oh, all right!" Brendan then walked up the stairs to May's room.
"Hello you must be Brendan, my parents told me you and your family were going to be our neighbors! I forgot to introduce myself, my name is May!"
Now let's just summarize what happened. Brendan and May began to hang out often and then they fell in love. Since it was legal for 14 year olds to get married at Little Root in the year 1998, Brendan and May did and since Brendan didn't have a last name he took May's. Thomas and May's older sister Anca got married as well. A few years later May and Brendan had a son named Max. Though, sadly, Brendan had to move back to the Johto Region. [But he would come back to Little Root Town in 2003.]
Now let us go to Domino City in the year 1994. When Marik Ishtar first came to Domino City when he was 10; he met Mai Valentine [she was also 10]. They became close friends and later fell in love. Then when they were both 14 in 1998 they got married. Within the next year they had a son named Yugi. Though, since they wanted to work they left Yugi on the Muto's door step. Marik and Mai then went to Little Root Town to live with Mai's sister May.
