Mine is Grumpig. I like this psychic pig with elements of that "Pearls before Swine" quote from the Christian Bible that I was named after. It wears a lot of pearls on itself, and it's a good dancer. The abilities it has imply that it's a foodie species that goes at its own whims and tries to set its own pace for life.
Mine has to be the Gastly line, with Haunter being my favorite. I just like the look of him, classic scary pumpkin face, so mischievous! And reminds me of Pokemon Tower in Lavender Town... spooky!!
Gastly and crew are Ghost/Poison, not Psychic. Good picks, though, I adore that line! PL:A is the first time I ever had a Gengar of my own, as I never had any friends to trade with growing up. 😅 So Haunter was the "final evolution" for me for a LOOONG time. Probably why I like it the most of the three, as well.
