Cementrieon (cement- tree- on) The sharp stone pokemon and the evolved form of eevee Cementrieon live in rocky mountain regions, their form varying based on their altitude and what rocks can be found there. The rocks on it's back are used as armor, it finds these rocks based on where it lives. The kinds of rocks also affecting it's move pool.

It's sedimentary form is found at the base of mountains, near rivers and caves, where it finds the sedimentary rocks that cover it's back. It's armor is the weakest of all forms, and allowing it to move faster. It spends much of it's time looking for more rocks to replace the broken pieces of it's armor. This form can also easily learn water type moves alongside rock type ones.

It's metamorphic form is found around the mid point and higher on mountains. It roams freely, digging out a cave in the mountainside for shelter at night. This is also how it gets the metamorphic rocks that make up the armor on it's back. These pokemon roam around often looking for quartz, the metamorphic rock it most prefers on it's back. This form can also easily learn fighting type moves alongside rock type ones.

It's Igneous form is found deep in caves at the high mid point of mountains and below. It's mostly found near lava inside these caves, or around fire type pokemon, using the heat to mend the armor on it's back, or add to it. It's armor is the strongest of all forms, also making it the slowest. It often comes out of it's caves during the day looking for food. This form can also easily learn fire type moves alongside rock type ones.

And that's it. All the info I got so fair on Cementrieon :3
