Well, there are not a lot of moons for dwarf planets so I might add them all here.
Lets start off with Pluto's moons!
Charon(Artwork:28th February)
Charon is the largest moon in Pluto's system. Actually, they have been referred as 'sisters' because she is a 'Pluto' kind of large. She acts sisterly to the other satellites, even when they feel a bit unpleasant. Although Pluto's demotion has given her a wave of sadness, Charon would still be here, helping the planet to her former glory!
Styx & Nix(Artwork: 1st March)
Well, they have the same rhyme and their traits are the same, almost as if they were actual twins. They are both sassy, little lunas that act as cool as they wanted to. The only thing is that Styx is a water type who can control the rivers, while Nix is a dark type who pollutes the area in darkness (Usually mischievously).
Keberos and Hydra(Artwork: 2nd March)
Well, it's not just kids Pluto have, She has pets too! Multi-headed ones in fact. Keberos is (Obviously) a Cerberus who is... basically a doggy version of a satellite, Cupid: Affectionate and cuddly. As for Hydra, well, every nine of its heads have their own personality. In fact, before being demoted to a dwarf planet, Pluto noticed that each head has a similar personality to her former planet friends, so she named them after those (Including herself).
Haumea's moons are next!
Hi'aka and Namaka(Artwork: 28th February)
Sometimes nicknamed as Rudolph (For Hi'aka) and Blitzen (For Namaka), they are both quite tender. Hi'aka is a unicorn who is quite magical (For a satellite) and enjoys playing along with it, much to her mother's dismay. While Namaka, is a pegasus who enjoys drifting in the cosmic oceans. Although, they may also have other things out of their reach.
Makemake's moons are there!
Mk2(Artwork: 4th March)
MK2 is the only satellite of Makemake (And probably the only one). his personality is a bit similar to one of Mars' moons, Deimos, but less extreme, as in, can actually sleep and stand still. He doesn't mind a little time spent to play with Dysnomia, and is more easygoing. One thing is certain: They both disliked loneliness.
Now, ending with Eris'
Dysnomia(Artwork: 3rd March)
Dysnomia is the only satellite of Eris (And will stay that way). Of course, Eris represents chaos and discord, so it's quite fitting for Dysnomia to have the same energy, adding a tablespoon of hyperactivity in the ingredients of her personality. Despite this, Dysnomia have a few lunar friends to play with, like Nix, or sometimes, MK2, it's just that she has have a bit of a mischief streak.
