Horsea, Seadra
I think it’s too easy to take a great name for granted. But “Horsea” is a masterpiece. It works in every single direction, from inverting “Seahorse” to punning on “horsey,” and there must have been so many high-fives when someone said it out loud the first time.
And yup, you’re right, Kingdra wasn’t around until Gen II. Although Seadra has always looked the coolest of the three.
