Mar: The first Marshmallon, and the first Ascended Marshmallon.
Facts that I didn't have space to put on the ref page:

• The "wings" also function as an additional set of hands, but only have an effective range of a couple of meters.
  -- They grant Mar the ability to float as well, how is yet to be figured out, though.

• They can change their height, but only to double their normal height (6'6"). Usually the reason they do so is to either reach for things with their actual "hands", or to show dominance to inferior species .

• Can create regular Marshmallons by tearing off a good chunk of their body-mass and granting it it's own consciousness.

• It's not certain how the ring at the end of their tail releases the slime, but considering that if they wag their tail fast enough while exuding one of their slimes it creates bubbles, it's thought to have similar properties to a bubble wand.
  -- however none of the slimes affect Mar, which makes sense for two of them, but it's a shame that the sleep and emotion slime doesn't work on them.

• Was formerly human, hence their hatred for humanity.
  -- This doesn't mean they would push to annihilate the human race, just that they would generally distrust humans aside from special cases.

• Has errant mood-swings at times, due to memories of their past bubbling up at the wrong time.
  -- Though if they get angry, it's usually expected for them to break down crying soon after.

• Has a pocket dimension inside them to store all currently unneeded mass.
  -- As noted above, they can give themselves breasts, as well as adjust the placement of their mass in their body.

• The Diap was a gift from a friend.
