I have recently procured a Black Pegasus in Minecraft, via the breeding of a Pegasus and a Unicorn. Now, the Black Pegasus being the best of all horses, this one needs a name. I can't pick which. Your options are either Sleipnir or Shadowfax (I named one of my other horses Stybba, and still another Snowmane, so LOTR-based names are perfectly valid). Other options may be suggested, but nothing to do with MLP or I'll sic the Hounds of Tindalos on you.
