Tough call. I'd say it's a tie between Wargle and Ononokusu don't care if they're both overrated , but I also like these Mons and all of their prevos:
These are just the Mons I'm considering for my team (minus the ubers.) I think loads more look cute/badass (such as Bachura/Denchura. Just learned today that Bachura is 10cm long. Thing is freakin' adorable
Yessss You're avatar is darling Blanket Bug Kurumayu!
I like sceptile because he has high speed, and does fairly in battle. Plus he learns Dragon Claw.
Although I think a SwordsDance Leafeon could see itself in Competitive battle too.
My favorite type is actually Dark, BTW.
Isn't it obvious? I do too! I screamed when they first leaked Kurumiru. Deep inside I'm a real grass-fan, but since they are uh, not that strong in battle (no offense, seeing as you're a hard core Grass fan.), I usually do not show my love for Pokémon of that type. My favorites include Carnivine, Victreebel and Cacturne.
