So Shigeru in this AU event is going to turn into a being known as a Forenthieth. This will happen in the future where he kills Alex (instead of going on a journey with him to find a cure) after Shigeru is overtaken by the dark god when his gates goes out of control/the dark god seeps through it and possess him. He'll join Jern in amassing an army to revive the dark god and lay siege on the planet.

Forenthieths are basically super powered phrobiests that are more in touch with the dark god (to do its bidding more or less) with additional powers via the dark god. He'll have his eldritch black tentacle powers that disintegrate everything they touch alongside with a case of the nasties.

He'll be smooth talking and manipulative along with a deep rooted evil streak. He'll also look quite different in that his eyes will be black and purple and he'll have rune marks along the right side of his body up to his neck. He'll also have his voice back. He'll remember his time in Riverview so if anyone wants to deal with this trainwreck let us plot.
