Some Outback Fakemon

-Choiren/Cantoren/Vociferen
Normal/Flying
This family of wrens/peacocks resembles a choir in design.  Their colors are monochrome.  The final stage evokes a maestro in its design.  Evoking the Sydney Opera House is fine if you choose to.

-Plebbin/Scholace/Zensei
Fighting, Fighting, Fighting/Psychic respectively
This Pokemon starts out large and naive.  It gets smaller, but still more powerful, as it evolves.  This Pokemon's design evokes a bear and a monkey, and as it changes it becomes more monkey than bear.  Their designs are revolved around a student, warrior, and sensei respectively.

-Mannawar
Water/Fighting
Based on the Portuguese man-o-war, this Pokemon is a small jellyfish which uses water to form a larger body.  The jellyfish controls it while the water exoskeleton is used as armor/weaponry.
