Nathan Mertes has Down Syndrome. He loves to joke around and make people laugh. He loves to imitate his favorite channels, SML, McJuggerNuggets, Youtube poop, React channels, Mario channels, and so many more. Nathan LOVES music, playing video games (especially Mario Bros Brawl), scary movies, and lots more. See and like his facebook pages, one called Nathanofadown is a family friendly page for all to get smiles, and then there's Nathanofadown Uncensored for the not so family friendly posts. lol And just for everyone's information his username is from both Down Syndrome and the System of a Down group that he loves so much.
