Flash Sentry is a pegasus and a guard for the Crystal Empire, though there are rumors that he practices the guitar much like his human counterpart. He is kind, gentle, benevolent, and a true gentleman. Other than that, there is not too much known about him. But if one where to take his human counterpart into account, he is almost relatively the same except for a few differences.
As there is not too much about Flash Sentry other than him being akin to a knight, he can fit into various stories involving MLP or other verses.
