Virvamon

Evolution... Virvamon's design based on a creature called "Fogoat "created in 2003 or 2004... Afterwards it was perfect for the evolution line of Usvamon and became a she. ... Virvamon evolves further into Faunamon but I haven't better picture yet...

Virvamon, Usvamon's Adult/Champion level (aka Seijukuki the original term...), Vaccine attribute, Mythical Animal type. Virva is short of virvatuli (Finnish), will-o'-the-wisp.
Mist continuously evaporates from her mane, tail, fur of feet and wings. Her "wings", though, aren't real but only wing shaped dense fog so Virvamon can't fly...she has an ability to walk on water, though. She can vaporize water or condensate vapor, even has ability to sublimation and deposition (everything where's something hazy elements). One of her attacks is that she creates blades from just liquid water, she can control water kind a well...
Her personality doesn't change during evolution so she's still nice monster, who just may be too talkative sometimes.

Hivemon -> Karemon -> Usvamon -> Virvamon -> Faunamon -> ?
