If Yodes are blessed by Hestia and Nemesis, then Plant Demons are blessed by Hecate, the Titan of magic.

Pladems are the souls of plants that Hecate blessed to keep the Earth stable.

They take the form of plants with eyes and a mouth with a pot underneath, though some prefer not to, walking with their slippery by able roots.

They, like every other normal plant, need nutrients to be able to fight. In this case, they use specialised water drops containing what they need, given by Hecate as a gift. When all the water drops are gone, they have to jump into a water source or fade away into the afterlife.

Pladems can have flowers, but in general they are usually quite slow in germinating. When they wilt, they pass on.

Right now, only Frisk is known to be an acknowledger of Pladems and Youkai.
