A well known pro at pretty much all games. If you name a game which came out in the past 3 years; free or not, he has played it and will be a very high rank/level. He is especially known for being one of the first 100 people to reach level 100 on maple story in 2005. SlyManiac has owned many sites in the past and can make awesome graphics with photoshop and can code in C++, VB, and C. SlyManiac has hacked many sites in the past but has given that up after he got fined $2,000.
