Many might remember his characters in Shadow Remains as:
Deconasia (main on ER from Sunwell -> Firelands, moved to Void of Mug'thol for the end of Cataclysm and now in Ascent of Thrall for Mists of Pandaria)
Right now, Aries has had an amazing season, including the 4 fastest times in the world this year (12.93 three times earlier this month and 12.94 earlier today to qualify for the finals) and is the top contender for gold.
His main rivals consist of Jason Richardson (USA) who is the 2011 110m Outdoors World Champion, and Dayron Robles, the 2008 Beijing Olympic Champion and World Record holder (12.87).
Wish him good luck for gold representing the USA!
