Now for something overdue. From the top right down:
Peagment (normal/flying)
A portmanteau of peachick and pigment, originally the idea was for it to come in eighteen colors, one for each pokemon type.
Peallet (normal(male) normal/flying (female) (level up peagment))
A portmanteau of peafowl and pallet. There are more female than male members. Males possess the ability "Pallet Swap" where its type and color change randomly each turn. A backstory where it, Eevee, and Kecleon were the genetic material used to make Type:Null.
