the time is this year.
Starlight glimmer (human version) has opened the realm to the world, and has teamed up with her father, whom is a special ops militia sergeant whom hat discovered equestrian, and is informed of all it's lore and sub plots.
He is intrigued at the concept of magic. What if it goes into the wrong hands? What happens to magic in his realm? After careful decision starlight father has agreed to show the general only glimpses of this situation, and tells the general it's a minor threat. He shows twilight, starlight, and the mane 6 using powers with video evidence, and says this is either a: some sort of foreign technology they're using as a weapon, or B: advanced weaponry from other countries that were purposely given to them, and they are all cells of a foreign terror organization.
The general after review of the evidence has declared a standstill until there ius an attack on u.s. soil.The mane 6 are captured, along with everyone else whom had to do with magic, and they start speaking of equestrian, and etc. The general sees this as some sort of mkultra code and these teens are obviously victims of a psy-op operation. Not wanting to cause panic among the civilians, the general sends them back but under close watch and in a different school
1 week later.
either Trixie or scumbag sunburst becomes evil and they open up a portal to the earth.
Sunburst uses magic on earth twilight, and glimmers father sees this as an attack. The police are informed, and have been briefed of magic potential sunburst after much resistance is shot in the head with a smart bullet designed to expel magic.
He is wounded but is not dead. But then he has an army of followers.and they start attacking on u.s. soil.
Magic and shapeshifting is used, but there are counter spells from adult magicians, after major loss the general is forced to send missiles to sunbursts now captured crystal empire. Shining armors troop flys in defense and poses white flags but to no avail.
