Sidereal is no long a exe character created by Twitter user NukedKola. His regular form was created on December 5th, 2021, whereas his 'Nightmare' form was created the previous day, on December 4th. 2021.
== Overview ==
Sidereal is a lonely Exe that spends long hours, days, weeks, however long just waiting for a friend. Starved for attention, he would do or say anything possible just to keep anyone's company. He wants anyone to be his best friend. Forever.
Sidereal's design consists of some bruising, slightly torn gloves and shoes, and tired eyes. All due to tireless running that would result in tripping and falling after some time. Color palette is more muted.
Nightmare's design consists of more open gloves and shoes torn revealing skeletal hands and feet. While his left leg is entirely torn, part of his right leg still remains. The lower parts of his arms are also torn. His chest has a large, torn-open hole in it revealing part of his ribcage, as well as several eyes from within his body. He has an elongated tongue, with teeth forming it into a separate mouth near its end. His colors are darker but more saturated. The sclerae are also black with widened black pupils and glowing yellow ringed irises.
== Biography ==
Sidereal is a rendition of a Sonic fan-game demo (titled Sonic: Sidereal Runway), where he's located on a strange moon planet with nothing but a Green Hill Zone-like area. The difference being that the terrain is mostly rocky and moon-like, having craters, caves and valleys with patches of crystals that were formed about. The sky is always black with very small traces of stars in the sky. He was in the process of being made into something different, in a different world. But the creator only had a short demo of the Act 1 (Moon Runner), Act 2 (Shining Valley), and Act 3 (Home), only to pass away from an underlying illness and never finished the game. The project was abandoned all together and Sidereal lingers in the internet space for some time until he can finally be met with a player.
== Abilities/Weakness ==
=== Abilities ===
Sidereal (Pre-Nightmare) has no abilities at this phase but functions like the normal Sonic, sharing his superspeed and other abilities the original Sonic possessed.
Mid-Phase Sidereal will go the extra mile to stalk the player through PC and sometimes cause minor errors in other software and games long enough to possibly convince the player to spend more time with him instead. The damage is not permanent however unless it's a save file.
Nightmare will not only stalk the player but will gain ability to move along webspace and even through other technology, such as TV, monitors, other game platforms etc.
He will also cause disturbances as often as possible and become subtle to notice in different media (as a Sidereal) in means of stalking or convincing the player their mind isn't right.
Through attempted uninstallment, Nightmare will persistently harass and make this process difficult through screen glitches, pulling the cursor or disabling it, [Error: <//3] pop-ups, or failsafe into faking a blue screen for 5 minutes as to not be deleted. His intentions are never to kill the player. He wants them to suffer mentally for the abandonment.
If uninstallment is successful, which is likely, he will take minimal time to escape into the webspace.
=== Weaknesses ===
Leaving Sidereal isolated in his own game and showing firm dominance will have him cower. However, this only works when he's pre-Nightmare. Having a balance of kindness and firmness will neutralize his other abilities from working and advancing.
Mid-Phase into becoming Nightmare, he will show signs of being non-submissive and irate/impatient. At this phase, he will not back down easily.
Fully turning into Sidereal Nightmare, the only weakness is being put into submission by another Exe as Nightmare will easily cower at the very instance of a challenge, reverting back into Sidereal.
== Trivia ==
* His name was thought of by KGBepis.
** Comgaming_Nz also helped with some concept ideas for Sidereal.
* Despite similarities to Monika from Doki Doki Literature Club, these similarities were not intentional.
* The main concept for Sidereal was inspired from the loneliness state Sonic had dealt with in the live-action Sonic the Hedgehog film.
* Sidereal was originally intended as a simple concept for the SAVE-A-SOUL Event on Twitter for charity challenges but developed over time days later.
* The game's title screen varies in different text of welcoming the player. When first opening the game, the title screen will say "Someone is there?" but never will show the game's actual given name.
* Rings and Emeralds don't exist in this game. However, there are star-like rings within the game.
* Tails, Knuckles, Amy, Robotnik, and other characters alike never existed in the game. Sidereal will not recognize any of the characters if shown them.
* How Sidereal's form can shift into Nightmare varies in different reasons.
* Extreme-sided dominant behavior can cause a [Error: <//3], causing Sidereal to close the game and not show himself for an hour.
** Uninstalling Sidereal before any of the other phases also results in an [Error: <//3]
*** [Error: <//3] is a minor error message that will close the Sidereal software.
* Sidereal will always try to talk to player through the menu screens.
* Paused screens or idle animation, even for 5 seconds, will result in an anxious Sidereal waiting for the player to return.
* At the end of Act 3, Sidereal will be able to interact with the player through visual novel type simulation. It is unknown if this was intentional to the original game or not.
* At a certain level of jealousy (and not visiting him in his game for a certain period of time), Sidereal will try to mod himself into another game existing in the PC system- though there's a possibility he might not be playable and will end up crashing the game instead.
* While Nightmare isn't likely to violently lash out at anything, he is prone to temper tantrums.
* Nightmare usually displays bratty behavior if he's upset- another level of distress is developing polycoria (multiple pupils/irises) the more distressed he gets.
* Sidereal's alignment heavily relies on relationship stability and whoever keeps him in line.
* Sidereal has survived off cave water in Home that provided enough minerals to keep him sustained.
* Sidereal is always cold in his world.
* Home was not the intentional name of Act 3.
* Sidereal has no concept of love, but would likely mistake it for a more affectionate friendship.
