>>28696702Nyx is the personification of night, and poison is just generally thought of in a darker sense, so night made sense to me for it
also I would've used it for Chandelure (makes more sense if used on one) but I could literally not think of another good nickname for
her. Plus both Scolipede and Nyx are feminine to me, another reason I chose Nyx.
And the Undine one is mostly because of hyper voice on Gardevoir, one of the moves that I use a lot on my Gardevoir sets. Also, it's shiny and the color scheme reminded me of how Undines are portrayed. Plus, Gardevoir is just mysterious and nymph-like in general.
