Captain of Sealab
He's gone Loony thinking he's the Second Coming of Christ.That's an interesting idea but his very first Twitter account in 2010 was already "CWCSonichu". (See https://sonichu.com/cwcki/Twitter)
At this point, though, who's to say what his justification is now, why he signed the court documents "Chris Chan Sonichu" in 2018 or why he would say that the Sonichu name is on his current Twitter. Maybe he would claim that now it's because of his marriage to Magi-Chan. The concept of his being "half Sonichu" may also factor in.
But to one degree or another he had "Sonichu" in his various names and identities for long time now, and I don't think many Christorians have really paid enough attention to what that might mean. The Idea Guy was able to influence him in the first place, in his own words, "Because he sees Sonichu as being present with him". That's a level of near-identification that we weren't aware of at the time, even though looking back there were a few hints.
