Seriously, there's more than enough potential ideas for fanfics involving the Pillar Men in Equestria. Like, imagine Kars literally crashing down to Equestria or maybe Esidisi and Wham/Wamuu being reincarnated with maybe some memories of their past lives or maybe just in new pony bodies or I don't know what. Or heck, maybe even having Santana get dragged over to Equestria somehow. I don't know. All I know is, we need more stories involving the Pillar Men.
