Probably not Pokemon

[Toastfighter]

For his tail, try redoing it using dithering, that looks more smokey in my opinion.

[Chris2Balls [:B]]

For now, the tail looks like... uh... poop.
You'll have to break down the form into clusters, and make sure you look up some smoke references. I think the colour ramp/usage on the tail seems too contrasted for now.

I don't recommend dithering unless it's on background, besides, it destroys shading.

Keep going!

More Pokemon? Sure.

[Lexou Duck]

Try to make him change more between evolutions, right now, hes just getting bigger and angrier each time he evolves, there should be more to it than that.

[megaMasquerain]

I'm not sure what I could add without making it too detailed (which is apparently an issue I have when designing fakemon).

Would simplifying the first and second evos more work?

[BynineB]

You could make them change in colour, and give them different patterns. They never stay exactly the same shade.

[StarSock64]

I think the third one's chest hair might look a little better if it was more symmetrical, and maybe with a more interesting pose. I'm not sure how I feel about the angles of the spikes. If they're supposed to be like those big spikey clubs, a more uniform pattern might make them more convincing as a weapon.

What are they supposed to be based off? That might help generate some ideas.

[megaMasquerain]

They're based on Oni, as well as the Japanese phrase "oni ni kanabo" - "an ogre with an iron club" - which means total overkill. (info from the Obakemono project page, to give proper credit).

I know a fair bit of oni lore but I'm still worried about making the Pokemon themselves too complex.

[Triangle Man]

You know what would make a really cool Pokémon? One that looked like a triangle! You could even spruce it up with a few pyramids to add a nice 3-D vibe. Porygon.

[Vipershark]

Okay man I've only seen you post in like three threads so far and your triangle thing is already getting really fucking old.

Either you're spamming for 20 posts, a troll, or really dumb.
Stop it.

[Maxpphire]

It's ok, he can't post for 12 hours anyway. If he persists after that he'll probably get 100% warn then autobanned for that.

I think the arm clubs are developed enough in the 2nd form, the third form feels "just like the 2nd, except BIGGER!!!", which sounds like a cop out to me. You could try making hands grow out of it for the 3rd form, or some other twist. You could also make the clubs different shapes, like the current one is more of a round shape, while you could try a more polygonal shape like here. Another thing you could try is having the tail grow a club too. You can also vary the number of horns on each on, in addition to the shape as you're currently doing. The 1st form could have 1 or none (incidentally the horns are red instead of white), and 3rd one could have 3 or 4.

By the way, you ARE going to make a blue one, yes?

[megaMasquerain]

I like the idea of polygonal clubs on the last evo, more horns, as well as a club tail (or at least a spiked tail). I'll go ahead and do those when I have the time.

And yes, the shinies are blue.

First of all, Go Japanese mythology! Secondly, what type is it? Ghost? Fighting? Dark? It could have different forms depending on the type.
