Flash may not have much to him as a character, but he really deserves better from the fandom and from the show itself.
I mean seriously! People treat him as if he’s a stalker or murderer sometimes, all because he "stole the waifu".
Honestly, people who hate him because he’s shipped with Twilight need to get over themselves. Twilight doesn’t belong to anyone, and she’s a FICTIONAL CHARACTER. If you wanna ship her with your OC or somepony else so bad then just do it, canon has never stopped shipping before. 🙄
I still can’t believe he was reduced to a minor character because of some angry possessive bronies. Ridiculous.
"Oh but he’s so bland and boring", there are plenty of background characters with barely any character at all that the fandom adores. So that isn’t really a valid excuse for excessive hate.
Personally, I really like Flash. He may be the classic "cute popular nice guy", but he’s got other things to him. He’s shown to be prone to frustration in one of the shorts, and he has a desire for adventure and to be helpful, as he expressed that he’s wanted to go on a magical adventure with the girls to Sunset in one of the shorts. (He’s probably gonna have a future career similar to that have his pony counterpart).
He actually has a lot of potential as a character that the writers just never touched unfortunately. (Thanks bronies).
Plus, he’s just fun to watch for me. 😄
And regarding his relationship with Twilight, I personally enjoy the ship. As cliché as it may be. They’re really cute. Loved how he joined her crazy dance. XD
Though I know Princess Twilight and Human Flash wouldn’t be able to have a future together, Pony Flash and Twilight might. I’d love to see them start as good friends with small crushes and watch it develop to love over time. All while developing Pony Flash as his own character of course.
All in all, I like Flash and feel that he has a lot of potential. And he’s wildly overhated by the fandom for dumb reasons.
