Chandelure, Whimsicott, Reshiram, Reuniclus, Hydreigon, Serperior, Snivy, Ohsawott, Joltik and Lilligant make the top ten. Check the full list on the link above. It's a Nintendo Dream survey.
Tympole and Stunfisk have become Japanese forum memes by the way, that probably explains why they're on the list. Lots of cute Pokemon in the top 30. A lot of my own favorites are in there too! Whimsicott, Reuniclus, Oshawott and Lilligant, congrats~
