Not a specific pokemon but...
I would love to see a Chinese or Lunar New Year themed event
I'm not an artist, nor do I hold much experience in this sort of field however this theme opens up to alot of potential designs for numerous Pokemon that could easily fit it in my eyes:
- Magikarp and Gyarados are originally inspired by Chinese mythology, and are also lacking a heavily demanded form.
- Meowth and Persian both currently lack a form and could easily be adapted into a tiger inspired form, fitting the Chinese zodiac sign.
- Litwik, Lampent and Chandelure can all be turned into a festive lantern however they already possess a christmas form, so any pokemon that can fit into this idea that currently does not have a form would also work.
- Tauros another pokemon fitting the zodiac sign of the ox, also currently in game without a form.
- Pikachu's evolution line could get another form added onto its many to fit the mouse zodiac sign, although many other pokemon could also fit the description such as Dedenne, Plusle and Minun, Marill evolution line, Ratatta (however they just recieved the summer form) etc.
- The Rooster zodiac sign could be filled out by Torchic's evolution line, or perhaps Unfezant's, not sure how they would look but the idea is out there.
These are just some obvious ones that first come to mind, mostly because of their original inspiration or the animal they are supposed to represent, let me know if you have any suggestions to the list!
