Phantump
The Stump Pokémon
Type: Ghost/Grass
Official Registration #: 708
Entry: This small spirit pokémon is actually a stump possessed by the soul of a child who died while lost in a forest. In light of this, the author once attempted to convince the Pokémon Association to ban the use of this pokémon in battles … until it was found out that in many cases, this is a dream come true for the child-turned-phantump, and to make a long story short, the author spent the next few weeks questioning his life decisions and the world as a whole.
Trevenant
The Elder Tree Pokémon
Type: Ghost/Grass
Official Registration #: 709
Entry: The evolved form of phantump, via trading. Using its roots as a nervous system, trevenant has the power to tap into and manipulate the trees around it. It most often uses this ability to trap those who harm the forest, but every so often, it traps and confuses children as well, who subsequently die and become phantump. Because no one is more brutal towards children than the spirits of other children, apparently.
