What you have to do is explain how Elementals are different than Demons. As well as how the Elementals improve their look and power through upgrades. Fire, Ice, Electricity, Darkness, Metal (Lethal), and Earth are probably the closest you can get. Since Psionics is very debatable as to whether you can have a Psionic Elemental and Toxic is composed of more than one element.
The first step in being sane is to admit that you are insane.

It appears that elementals is already there
I know itÂ’s a little different but I was thinking instead of have the same three guys that came along then the same two and then the one of a kind you get at the end. I was thinking of taking the idea of demon summing and using it in a slightly different way in which case you get 6 elementals each wilding a different kind of power pertaining to a different element. I was also thinking like the demons lets break the mold a little agene and not make them look like a human or anything but something completely devoid of that.
