Infused eeveelutions 2

Dual-type eeveelutions feature in Pokemon Storm/Wave's (free) DLC, with the introduction of a special area that heightens the power of Infusion stones. Using the right stone on an eeveelution here will cause its cells to mutate again, as it takes on a secondary type and changes its form. And yes technically Infused sylveon should have been with the next set but whatever. Also a slight redesign for kadatheon - I'm not sure I necessarily like this one better though.

Kadatheon, the dream-quest pokemon

Kadatheon is the result of giving an espeon an Infused Amber in the Infusion Chamber. It spends a lot of its time sleeping, up to 16 hours a day, but apparently that's so it can astrally-project itself into the land of dreams. Other dream-walking pokemon like musharna and hypno give kadatheons a wide berth, and may even hesitate to battle them in the waking world. With their third eye, they constantly monitor the heavens for omens, even when otherwise asleep.

Obsideon, the masked pokemon

Obsideon is the result of giving an umbreon an Infused Onyx in the Infusion Chamber. Its smooth body has a quality like polished stone, and it can sit as still as a statue for days on end. The funerary mask it wears is never removed - what it eats, and how, is unknown. In ancient times it protected the resting places of dead kings from ghosts and curses, absorbing them into its body and paying them back one hundred-fold. How ancient peoples halfway across the world learned of and utilized Infusion though is a mystery, one obsideons aren't interested in telling.

Mageon, the haunted forest pokemon

Mageon is the result of giving a sylveon an Infused Carnelian in the Infusion Chamber. These tricky pokemon live in deep forests, foggy moors, and untracked swampland, and use their understanding of emotions to manipulate others into doing their bidding. Those who can't be controlled are instead scared away with curses and hexes of dire potency. Wild mageons mainly want to be left alone, and will retreat to cover while their confused foes struggle. Among some Osaigon, mageons are nicknamed "enbeon", but the reason for this has eluded researchers.
