You cannot be a squishy grub in Pathfinder, which is a national outrage. When the Lost Omens Ancestry Guide comes out, however, you CAN be a sprite with the fey sorcerer bloodline, which makes a perfect Butterfree.
Now that the Pathfinder Advanced Player's Guide is out, you can play a charmander/charizard in Pathfinder 2E. I'd suggest a red dragonscale kobold with an elemental bloodline (fire) and taking the Dragon Disciple archetype.
If I'm proud of anything on the upcoming Lost Omens World Guide for Pathfinder 2E, it's how the architecture turned out. My favorite piece of the bunch has to be Quantium. https://t.co/7Rxtkubsps
