IsabellaMouffette

She started as a pathfinder villainy thing. 

She's a elf who kind of made a deal with the devil(Albeit one of nature.) to fix her weak immune system by taking on a botanical virus.

As such the plant has some control over her as well as the human half, causing her human half to want to give back to life, and nature. Becoming a alchemist to aid in finding cures for diseases since she can't catch them herself. The plant also seems to be a bit vein/childish having dreams of stardom, and  flashes of envy. This caused her to develop a few mood altering concoctions, and poisons.

Her class combination is bard alchemist. meaning she is super good at status effecting her enemies to death, and buffing allies. Like legit these classes make mmorpg classes look bad at that kind of thing.

She can also be very old if it isn't the same cannon as her being young, Though she doesn't age without help often causing a bit of depression in the scenarios she does show up older. Often coming to the conclusion that life without death has no meaning, and appearing as a villain who uses poison or a neutral suicide doctor character.

The plant does not have feelings but is essentially a zombie virus that focuses on makings its host survive more then it cares about spreading knowing it's long life span, and that it will eventually spread if they feel the need to save someone with it. Though it's often wondered whether the virus makes her a coward, or she is just innately cowardly as after all she did take the virus rather then fight her weakness on her own.
