I was initially against tying it into Pokémon, but actually looking at this it basically has the same feel as the Doctrina stuff, so I think this is good! I can see some suggestions, I'll throw mine into the ring as well.
So if we're basing it on the stuff above, I think I'll suggest the following:
Sky - This is the one I'm most unsure on... primarily because actually attributing a Pokémon to what we'd mentioned earlier seems to be proving difficult. Based on that, I'm unsure on Altaria and am going to submit the following two as a result:
- Salamence
- Volcarona
Sea - +1 to Milotic, this was actually goint to by my suggestions because it just fits the whole vibre perfectly AND I wanted to see something serpentine in the mix.
Earth - Torterra is an interesting pick, I like it! Based on the idea of being unwavering, responsible, ambitious etc. I was also thinking of the following 'mons for Earth:
- Steelix
- Nidoqueen
- Nidoking
