MaJackO is a skilled South Korean player and level creator in Geometry Dash. He is well known for his distinct and messy art style, "Core," which contributed to revolutionizing the game. His most famous level series was his Core series, consisting of DubCore, GrindCore, EmoCore, MetalCore, 8-Bit Core, and TransCore. Additionally, his Insane Demons, Future demoness and Stereo Demoness, were regarded as two of the hardest levels in the game when they were originally released in their unnerfed states.
History[]
MaJackO joined during 1.2 but did not create a full-length level until 1.3. He created levels such as Gordian Knot, Atlantis, and Good Robot. These levels were detailed for 1.2, albeit its relatively small length. Then, he created his first full-length level in 1.3, Silent Hill, which was intricate for the time.
MaJacko took the #1 spot in the star leaderboards on February 3, 2014, for a short period after competing with DENM and saRy. However, he lost his stats on February 9, 2014, causing SaRy to return to the Top 1 again.[1]
After the deletion of Atlantis, he would work on the next project. This project would be a medieval-themed level known as Stereo Demoness. MaJackO hacked this level in its unnerfed state and posted it into the servers. When it got posted, it got flooded by dislikes. MaJackO would also get accused of using hacks to post the level, and a few updates later, it would get nerfed.

Trivia[]
- He had multiple previous usernames before changing it to "MaJackO."
- He was considered a hacker because of his levels at the time being difficult, notably Stereo Demoness, Future demoness, and Back on Mountain.
- He quit in late 1.9 after the release of Future demoness but returned shortly in 2019 to create a part in the mega-collaboration FinKor.
- Before 1.8, most of MaJackO's levels, such as GW Russia, were much harder than they are now. To prevent suspicion of hacking, MaJackO nerfed these levels to be much easier.
- Some of the levels that MaJackO made originally used one of the main songs. In 1.9, he would change most levels to use custom songs from Newgrounds, with some of the songs not being allowed for use.
- His most recent post was "finally comback im making new map" from three years ago. It seems he never finished this level.
