amatsu does have a forward charge like lagi's at the very least if I remember correctly. and the motions with his water spit are similar to lagi's lightning spit when hes underwater. I think he moves through the air kinda similarly to a leviathan swimming as well. it isn't very much, but there are some similar moves between amatsu and lagiacrus.
