Flash Sentry



"This pegasus stallion here is Flash Sentry. Leader of the Crystal Empire royal guard, even though he looks like he's coming out from the Equestrian royal guard. I knew he's Twilight Sparkle's love interest (whereas his human counterpart is also Susnet Shimmer's love interest, whenever she's just a pony or not; and even his love interest's human counterpart's love interest is also Timber Spruce). Does it sound confusing at all?"

--Su Ji-Hoon, The Two Sentries

Flash Sentry is a male Pegasus pony who first appears in My Little Pony Equestria Girls as a Crystal Empire royal guard. Following his appearance in Equestria Girls, he has since appeared in series episodes and several IDW comics.

In When the Cold Breeze Blows Away, he was first appeared as high-ranking royal guard in during the USRAC War but he also known for being princess Twilight Sparkle's husband (whereas his human counterpart's love interest is Sunset Shimmer while his love interest's human counterpart (Sci-Twi)'s love interest is Timber Spruce) even though he has been framed for ruining Dimitri Alexandre Blaiddyd's favorite moments after his human counterpart has been framed for ruining the favorite things of Jimmy Hopkins and Russell Northrop.

After World War III, he retired from guard duty, and eventually made a peaceful divorce from Twilight for letting him marry her original boyfriend, Comet Tail (and several months later, after Comet Tail died on stroke, Tempest Shadow). Three months after, he died on cancer that he got from severe radiation poisoning during the final battle of the Great P365 War from a few years ago, Battle of Siquihoof (because of Siquihoof being severly radiated due to a cobalt bomb attack from the Zebra Empire during the Equestrian-Zebrican War), and even worst of all, further severe radiation poisoning during the Battle for the Multiverse's reactor core leakage that led him to his slow demise, leaving his fiancée Sparkly Bright (a pegasus mare from Zephyr Heights working as a lawyer).

During his funeral, his human self (who was still alive towards the end of the events of this novel) is among one of his pallbearers, and inside his coffin, he wears both his fall formal suit from the Equestria Girls movie and his royal guard uniform.

In the far future where Congressman Andrews is in, he is reinterned to lie in his glass coffin with his body fully restored to lay beside his wife Twilight Sparkle, along with Comet Tail and Tempest Shadow.
