It's funny to notice that the persistent creatures who seem to want it after Sunny's life and the fact that they become all his shadows (especially if you look at Nighmare and imp), in my opinion after all his fights, the snake will end weak and Sunny will finish it as he did at the time with Saint and this one will become his shadow! Sunny would no longer be afraid of water with such a creature in his arsenal! And then finally Nephis is always faithful to herself! "I'm hungry, so let's go out"
The problem with this theory is that Sunny has no same Echos. Just think about it, he has Shadow Serpent. Would G3 give him another shadow of the same kin?Of course, I'm not against the idea, but If you ask me, the butterfly or another shadow that can fly, like the butterfly would make much more sense.He has a Mount, Nightmare. He has a Tank/Meat shield, Imp. He has a "warrior" of some sort, Saint. And he has the Shadow Serpent, a supporter, but more of an all-rounder. He only needs a flying mount, which in this arc to travel the Great River would come perfectly.
