User blog comment:Heroic412229/Who Should Be The True Main Antagonist Of Sonic Rectification?/@comment-39521143-20200120213103

Either Ominous himself or the Evil Energy thing, I'd say. I'm personally leaning more towards Ominous from a storyline standpoint, but at the same time, seeing Sonic and his friends fight an Evil Energy being would be kind of fun. So in other words, it's pretty much tied between those two when it comes to my opinion.

Hope this helps.
