C: is an entity that can appear in a copy of a Sonic game, or rarely, Super Mario Bros. Wonder.This is from an internal review, labeled SJM-832-RCF-272A. He most commonly manifests on the title screen of Sonic the Hedgehog where Sonic's face is replaced with "C:" in red. 
== Effects of C: in Sonic the Hedgehog ==
* Every instance of "Sonic" changing to "Sinoc",This is from a screenshot taken of Cursed Games Magazine in 1992. User-generated recreations of the "Sinoc" instance commonly swap the "O" and "I" in the image and call it a day. which may be C:'s real name.
* In Green Hill Zone, all of the trees missing their leaves. As Herobrine from Minecraft also does this, the two may be connected.
* C:, on a very rare circumstance, may permanently replace the player's copy of Sonic 1 with a Sonic ROM hack. The most common ROM hack it uses is one where Sonic becomes black with red eyes, with the next most common ROM hack replacing Sonic with Mario.
However, note that in some cases C: may be misinterpreted as a manifestation of Sonic.exe.
== Effects of C: in Super Mario Bros. Wonder ==
In Super Mario Bros. Wonder, SJM-832-RCF-272A's document notes C: as an "unknown entity" and the effects the document lists are as follows: (some parts are redacted)
* The entity can replace Mario with Sonic the Hedgehog, who appears black, as to resemble Shadow the Hedgehog, both from SEGA.
* The entity can erase all leaf assets, making trees appear as though they are missing leaves.
* On one test with the entity enabled, it can replace World One, Level Two with one the entity has created. The entity-generated W1, L2 commonly features dead characters that would give a CERO Z, PEGI 18, or ESRB Mature 17+ rating, and the generated level commonly features spamming of the Bowser boss, specifically the World W█████ version, which would crash a regular Nintendo Switch, but dev units can handle it. Levels look like ████, ████, and █████.
* The entity commonly replaces the ██████ enemy, making it look more like a █████ that is black with red eyes.
