Cybershell

Andrew Charles Kiker, more commonly known by his username, Cybershell, is a SonicTuber and an inspiration of the channel. His mysterious disappearance in January of 2018 sparked Matt's interest and subsequently made a video on the topic called "RIP Cybershell", properly starting his YouTube career, and is often referred to by Matt in an off-the-cuff manner ("Thanks, Andrew!") in several videos, beginning with the Sonic 2 episode of Matt Reviews. Matt revisited RIP Cybershell in a editorial entitled "The Curious Case of Cybershell", nearly 1 year later.

Background
Cyber, in his own words, made videos "about a blue cartoon rat." His raw sarcasm and tendency to swear a lot, coupled with his edgy jokes, was interesting to view in comparison to other, more serious Sonic channels.

Cyber's infamous disappearance in 2018 was enough to capture Matt's attention, considering that the internet was witch-hunting him. Cybershell returned in 2020.
