Hasbro has named you the new show director. Congrats! Your first mandate in this new position is to give the Mane 6 all new stallion love interests. Your job is to now craft personalities for these new characters and develop their relationships with the M6 without detracting too much from the actual show.

These must be new (not already existing) characters.
They must be stallions.
Not doing the job would just get you fired and somebody else would come in to replace you.
