'''Supersonic''' is a [[Update 1.9|1.9]]-[[Update 2.1|2.1]] Insane Demon mega-collaboration level published by [[ZenthicAlpha]], who also verified it. It is the first instalment in the Sonic Series, preceding [[UltraSonic]]. Supersonic was considered among the most difficult levels of its time, with several memory-heavy ball, cube and UFO sections, moderately tight ship and wave segments scattered throughout the level, and its notoriously difficult final ship segment at the very end of the level.

==Description==
*'''0-6% (Glittershroom):''' Supersonic begins with a double-speed ship segment, with fading blocks, spikes and saws as the obstacles. Memorisation here does not play a big role because the obstacles are visible for only a short time before fading. Gravity portals also exist in this part.
*'''6-18% ([[Jeyzor]]):''' With the player still being at double speed, they turn into a wave. Here, the player must spam accordingly and pay attention to the level because of the fake routes. There are two 'X' signs here; only the first one should be followed, as the other will kill the player on contact. After that, the player turns into a mini-UFO with lots of fading saws. A click pattern is required here, and then the player must take the correct path (the lower one).
*'''18-26% (Sumsar):''' Sumsar's part starts with a relatively simple cube section not requiring many timings. The player then enters a relatively tricky mini-ball section. Understanding the fakes and the physics of the slopes is crucial here.
*'''26-36% (Xcy7):''' As a ball, the player must avoid fake orbs and hit the real ones. This section ends with a corridor that requires timing. Following this, the player turns into a wave with somewhat tight spaces, then into a cube. This part also contains a skip located at the end (see Trivia).
*'''36-51% (DaddePro):''' The player, as a cube, jumps over a triple spike with a half-speed portal located above it before turning into a ship. This ship segment has tight spaces because of the spikes and saws. The player then turns into a cube again with a difficult timing before (once again) turning into a ship. Unlike the previous ship segment, this one has tighter spaces, and the player has to straight-fly diagonally. After this, the player enters a triple-speed wave requiring skilful manoeuvring. Gravity- and size portals are also located here, and the wave section is followed by a brief ship section as a transition to Evasium's part.
*'''51-65% (Evasium):''' Evasium's part is completely based on duals, unlike the previous parts. The first part is a dual-mini-cube section where the player must jump, hold, and hit orbs as the platforms fade. The second part is a dual-mini-ball section where the player must continue hitting orbs. The player must be careful here, as the timings is tricky.
**Note that there are two ways to enter Ggb0y's part. The first involves Player 1 at the top. In this case, the ship will descend lower, requiring the player to hold to pass. The second involves Player 2 at the top. In this case, the ship will descend higher than the first outcome, requiring the player to avoid holding for too long to avoid crashing.
*'''65-73% ([[Ggb0y]]):''' The player, as a mini-ship, has to fly through platforms while avoiding spikes. The fakes here make it less simple. The mini-UFO section that follows is much simpler and does not have strict timings.
*'''73-78% (ZenthicAlpha):''' The player enters a double-speed wave section with lots of size portals located here. The spaces are relatively tight, so the player, as the wave, must carefully manoeuvre.
*'''78-100% ([[Viprin]]):''' After manoeuvring as the wave, the player enters Viprin's part, starting with a memory ball section. The real and fake blocks here look almost identical, and the real ones glow a bit (unless Low Detail Mode is used). This section ends with an auto segment. Next is a triple-speed cube section with fake orbs and difficult timings, followed by a ship section that serves as the final part of the level, full of invisible saws and gravity portals, often considered one of the hardest parts of the level due to the fast speed and tight spaces.

==User coins==
*The first coin is located at 4%. After reaching the second upside-down portal on the ship, there is a half-invisible coin and a green orb. To get it, hold and click the green orb, some risky timings.
*The second coin is located at 34%. To get it, drop down to reach a risky turn on the wave.
*The third coin is located at 76%, and, unlike the other coins, this one is easy. To get it, hold in the second mini wave segment to reach the coin.

==Trivia==
*Due to the way level lengths were determined in Update 1.9, Supersonic was displayed as Extra-Long (XL) rather than Long before the coin update.
*Supersonic has a sequel called [[UltraSonic]], an Insane Demon created by the same team of Supersonic, excluding DaddePro.
*Supersonic was ranked #30 in Geometry Dash Today's list, 'The Top 100 Greatest Geometry Dash Levels Of All Time'.
*Supersonic is the only level in the Sonic Series with the 's' in 'sonic' being written with a lowercase letter in its title.
*It is possible to fail at 99%, as shown in this video: [https://www.youtube.com/watch?v=XV5WI3W2NDA Supersonic 99%]; however, the video is a run of ZenthicAlpha's part to that percentage.
*ZenthicAlpha reverified Supersonic with a coin update, but it later removed the coins.
**Supersonic received another coin update on 13 May 2020.
*It is possible to skip the half-speed portal and cube portal as a wave at 35.88%.
*On 1 April 2021, RobTop accidentally deleted all the comments from Supersonic.
*Supersonic is the most-liked and downloaded Insane Demon level.
*There is a remix level of Supersonic called Supersonic v2, created by Landest, which is 'misrated' as a 9-star level when its difficulty is approximately an Insane Demon.
*The achievement called 'Supersonic speed', added in [[Update 2.2]], was likely made in reference to this level.
