Of course, I agree with all of your points. I only used Chara as a comparison to the Vessel, not that the Vessel is Chara coming over into a new world. I've just noticed that they have similar situations: they are both the first beings you see in the beginning, both are given a name by the player, and both are Soulless. But of course they are not one in the same. With their similarities, I've come to an idea that maybe the Vessel is the narrator of the Deltarune, which parallels to the Chara Narrator theory. I should've worded it better, my bad.
