April Fools' Day 2018

The April Fools' Day 2018 channel event was a week-long takeover starring Inspector Gadget as channel host... again. However, this time Gadget is not alone, and he fights an army of video game reviewers lead by Nostalgia Critic.

Summary
"SiIvaGunner" suffers a major glitch and finally reveals himself as Inspector Gadget, who had once again taken control of the channel. However, a new faction in opposition of him rises up. This new group consists of internet reviewers led by the Nostalgia Critic. All of the rips involve Gadget, Nostalgia Critic or other reviewers.

The description is once again changed to "Go-Go Gadget Channel Description!" As well, the profile picture for the channel on Twitter and YouTube seem to be following this series of pictures from this Tumblr post.
