BUR #3350 has been approved by @evazion.
create alias black_pit -> dark_pit
As you may know, Black Pit is the Japanese name for Dark Pit in Kid Icarus Uprising. Danbooru usually uses the original Japanese names for most tags, but as there are already several posts for second tag, an alias seems like the way to go.
EDIT: The bulk update request #3350 (forum #171946) has been approved by @evazion.
