And one more... my gosh, my brain has been afflicted with inspiration- I had to do this one. It is a silly idea- but... I was thinking about a possible water type and my mind wandered toward those plastic rings that attach cans together and how they affect all sort of marine life.
-Pollutag | Water/Poison Type
The Fish Mimic pokemon
Pollutags are no fish. They plastic waste that acquired sentience from the pokemon who died from it. They are extremely hard to see underwater, almost invisible to the naked eye making them great predator within their ecosystem. They come in two different form, the number of rings determining their evolution.
-Tossablow | Water/Poison Type
The Big Fish Mimic pokemon
Tossablow traded their invisibility to something colorful and large all in order to attract larger preys. If a pokemon dares to eat them they will prevent this pokemon from breathing and drown them.
-Yokeel | Ghost/Poison Type
The Eel Mimic pokemon
While Tossablow went for the bright and flashy, Yokeel on the other end remained discreet predators. Their spine flashing bright colors to attract preys they quickly strike. tangling themselves over their prey.
