Since I've been making Pokémon for a while and I saw this thread, I thought I'd contribute, so here you go.
Two of the Pokémon (Jakuser & Fintom) are redesigns of Pokémon I made earlier, which can be found on CyberMaroon's dA.
Bambuma was designed to be this "generation"'s Pikachu.
Jakuser (Jakuzi+Geyser)
Type: Water/Fire
Platypus Pokémon
It heats the water in its body to a temperature way beyond boiling point. However, special fluids keep the water from vaporize.
Fintom (Fin+Phantom)
Type: Water/Ghost
Invisible Pokémon
Its clear body shows its internal organs. In water, this Pokémon is practically invisible. Fishers catch them by accident.
Bambuma (Bamboo+Kuma(Jap. for Bear))
Type: Electric
Panda Bear Pokémon
Its special jaws were made to crush bamboo. Since bamboo has very little nutrients, Bambuma must eat tons of it.
Here's my shot at the fossil Pokémon.
Buzzpine (Buzz saw+Spine/Spinosaurus)
Type: Dark/Steel
Blade Pokémon
Revive Sawtooth Fossil
A vicious Pokémon that roamed the land millions of years ago. It can curl up like a wheel and spin like a buzz saw, cutting through solid rock.
Tryich (Ichtryosaurus)
Type: Dark/Water
Whirlpool Pokémon
Revive Drill Fossil
A brutal Pokémon that rules the seas millions of years ago. It can spin really fast like a drill, causing whirlpools. Land Pokémon evolved from Tryich.
