This article is too damned short, Marine! You will help Gruntipedia by so it will fit the screen, fool!
Martemis Old Donald Duck (birth name) is a Irish comedian/songwriter/composer that had once been a cyborg, a member of the Spartan II project, the host of the game show Are You Smarter than a Grunt, a member of Bungie, and is famous for being intelligently smart as he has 777 IQ. He is also responsible for making all the rap beats for Da Crusadaz to rap over.
Martemis' parents were Artemis Fowl the Second and Samus Aran. This, unfortunately, led to him being American, with some Irish spots. Marty was known to be a child prodigy, as he could play the Halo theme song on the piano even though Halo wasn't even created yet. When Marty was 1 year, 3 months, 3 days, and 7 hours old, he was captured to become a member of the Spartan-II Project. Artemis Fowl the Second blamed Samus for this, as Samus was also a cyborg.
A genius composer, and genius all-round, he simultaneously invented time travel as well as the greatest symphonies of the greatest musicians the world has ever known. Sadly, a freak accident involving a Ken doll, a fork, and his mullet sent his creations back in time. Who would have known Mozart of Beethoven were plagiarists? The accident would haunt him the rest of his life.
