Cosima

My twilightXdiscord child, Cosima. I don't really ship them but I like how this design came out.

They exist in a universe where Discord escapes the elements of harmony and is presumed dead rather than being turned to stone. Discord and twilight had a short affair during the time discord had taken over ponyville and sometime after Discord fled he produced Cosima's egg (following the head canon that if a draconequus mates with a someone who isn't a draconequus, then the draconequus will birth the child, regardless of gender) swearing revenge on the mane 6, Discord raises Cosima to believe that Twilight abandoned them and the ponies of equestia wrongly persecuted them and tried to kill them both. When Cosima reaches adulthood they and Discord return to ponyvile, Discord to take over, Cosima to confront their mother and get revenge.
