Madan was born to Diablo and Isauara Atherton. They were both Mexican, and met at Hogwarts, his father being a Ravenclaw and his Mother a Hufflepuff. He has an older sister, Sara Atherton, and a younger sister Juliana Atherton.
Growing up he was close to his family, especially his older sister Sara. When she came home in tears day after day, because some boy her age was making fun of her calling her a 'Stupid Mexican', Madan became so enraged he went and beat the bully up. He never talked to Sara again, and no one dared tease her or Juliana, for if they did the wrath of Madan would come upon them.
When Madan received his Hogwarts Letter, he was super excited. He was sorted into Gryffindor. His first year was rather uneventful, but in his second year he met Kielo Lehti. They became fast friends, and started dating in third year. Unfortunately for the young couple, Kielo left for France in the beginning of fourth year. Madan spiraled into depression and learned the guitar to bring himself back out. He became very good at it.Then Kielo came back, but she was no longer interested. Madan made it his mission to win back her heart. He did so, at the beginning of fifth year, and they have been dating ever since. However he ended it on the train to their seventh year.
When Madan graduated he took a job as a Music Teacher and dated a long time friend named Alessandra D'Martin. However Alessandra was emotionally manipulative and clingy... something Madan didn't want to deal with. So he ended things when he got a letter from the Mexican National Team saying that they wanted him as keeper. Madan took the job, ended things with Alessa and fled the country.
While playing for the Mexican team, Madan met someone rather special... Maria Elena Ramos. However despite the mutual attraction it took a while to get them to date for one reason. The Mexican coach didn't players date other players. Madan's sister actually got kicked off the team for that. So they didn't date for a while and when they did start to date, they kept it secret. That is until after a match with England... Madan proposed to Elena back in the hotel. He was tired of hiding it and if the coach kicked them off... oh well. Luckily for Madan and Maria the coach didn't do that and gave up on that rule.
