'''Colon''' (also known as '''GD Colon''') is a Canadian player, level creator, and YouTuber. He is well known for uploading unique non-level videos, playing copies of [[Geometry Dash]] on several platforms, creating (usually 1.0-style) levels revolving around an original concept, and analysing features within the game. His current hardest Demon is [[Magma Bound]], beaten on 2 February 2026.<ref>https://www.youtube.com/watch?v=OZ0ZX9iTeuc</ref>

Colon also has five other accounts: Colon2ndAccount, where he posts previews, RobsVault, where he rips [[Robert Topala|RobTop's]] levels directly from the game to allow copying and using them, RobsBasement, where he ports levels from GD rip-offs and copies, tubular9, a joke account, and theworldmachine, a bot that posted randomly-generated levels from 2019-2021.

*Colon's YouTube channel rose in fame after uploading '[https://www.youtube.com/watch?v=qg5FDT6fjtc What NOT to put in your custom level]', a poorly made Windows Movie Maker video with over 1.8 million views. It remained his most popular video for several years until it was beaten by '[https://www.youtube.com/watch?v=D2uE051de0U Making Terrible Geometry Dash Ads]' in 2019.
**Colon released a complete remake of this video on 18 December 2017. However, it had poor quality due to an overlooked rendering error.
***The video title had been changed to 'really old bad video' for a long time, but it was changed to 'Geometry Dash - What NOT to put in your Level [OLD]'.
***It was later changed to '[OLD VIDEO, DO NOT WATCH] Geometry Dash - What NOT to put in your level'.
***It was then changed again and currently is called '[OLD/BAD VIDEO] Geometry Dash- What NOT to put in your Level'.
****A higher-quality reupload was released on 4 September 2018, and after this version had received enough views, the original was unlisted on 19 January 2019.

This audio is used in the rated level Shorts by Kanati.
*Colon's rant video about [https://www.youtube.com/watch?v=-sQk1lIDxws Geometry Dash Subzero's coins] quickly prompted RobTop to change almost all the coins in a new update.

**Other things that Colon dislikes are wall coins (and the secret coins that involve randomly falling), the Poison Gauntlet level [[Generation Retro]], and formerly the old wrong Pusab font (last mentioned in his video 'Old Geometry Dash Fangames' explaining that he is past this now).
***Colon created the subreddit r/PusabPolice dedicated to 'shaming those who use the old version of the main Pusab font'. He regretted creating it, stating: 'I accidentally dragged it out too far and dented the entire GD community. I'm really sorry for everything.'<ref>https://x.com/TheRealGDColon/status/1113193794663587841</ref>
****The subreddit was privatised on 2 April 2019.<ref>https://reddit.com/r/PusabPolice/</ref>
