#but the mechanics for that come from feeding on himans so i think perhaps pony lore is different

do you think if there were hippocampus in FIM (and I haven't seen the last few seasons so maybe there are fdjghjf but anyway) do you think alicorns would also have mermaid tails on top of the other features? (not a drawing suggestion I just really like your worldbuilding and want to know how you'd go about it)

There are indeed hippocampus! They start appearing in My Little Pony The Movie (2017) (good movie) (sexy villain) (amazing villain song)

Alicorns do not have seapony (hippocampus) traits because current pantheon of ascended alicorns came from ponies with no seapony genes. Seaponies are not anatomically compatible for terrestrial species, so there are no seapony traits in the ponish trifecta.

Anyway. A hippocampus could ascend to godhood but it would be different from the terrestrial alicorns due to their different origins. In fact, the ocean is so much bigger than the land, who's to say there aren't giant queens lurking in the depths, able to control the tide and weather?
