Today we have a stand-alone bruiser, the Hollow Pokemon Ashenhallo!
Pokedex: Ashenhallo passes itself as a normal tree, hiding within wooded areas. It protects it territory by moaning wildly and sometimes starting forest fires.
Ability: Chlorophyll or Lightningrod
Hit Points: 
Special Attack: 
Special Defense: 
Description: Ashenhallo is essentially modeled after a treant, basically being a walking tree with a face. The face resembles that of a jack-o-lantern, and looking inside of it certainly makes this Pokemon seem hollow. However, the inside of its trunk is lit by a blue flame that moves about within. The flame is small and hidden when Ashenhallo is dormant, but blazes wildly when the Pokemon is on the attack, often spewing out of the face and erupting from the top of the trunk. Ashenhallow's four (sometimes five) branches are all located near the top of its trunk, and have few leaves, all of which seem painted with a crimson color. These leaves can be set aflame as a means of attack, and grow back quickly after being burnt off. It crawls along the ground with its large, moveable roots and attacks by swinging its branches or breathing flames.
Evolution: Ashenhallow does not evolve.

At level 48, Ashenhallo learns the new move called Moan. The stats for the move are as follows:
Power Points: 20
Range: Single, non-contact
Moan's effect is that it harshly lowers the target's Special Attack stat.
No current moves serve this purpose, so this addition seems like a good idea. I, myself, can think of plenty of instances in which the move would prove useful.
And there you have it. Please leave any comments you like! I'd really appreciate feedback on this new Pokemon, whether it's a question, comment, or an issue that needs to be addressed.
