It was kind of a drawn out process until I decided I might as well make my own pony and accept my Brony FATE XP
All I really did was smile. To be honest I've not been into it that much until 10 episodes in, seen it on children TV casually and since I don't really bother switching the program I actually watched it casually without knowing about bronies and such. Later on (around a year later) I've seen one of the YouTubers I watch doing reactions to it and I watched some of them and while they were having fun watching it I couldn't help myself but smile along and thus I became a brony I guess. (Maybe I should mention that Luna Games was a huge factor in my interest as well)
Wow.... Oh man, how do I put this? Well, as you probably know, I did become attracted to the show, but I didn't really see how that would make me a Brony, so I never considered myself one. But then time went by, and one thing led to another, and in the end, I guess I became so attached that I decided I just had no choice but to just suck up and admit it. And honestly, I felt pretty good and I'm still pretty proud of it. Ciao.
At first I wasn't even aware I was a Brony, I watched part of an episode the first season and didn't really do anything about it for a long time, well into season 2 I gave it another chance because of all the hype and the realization that I loved this silly pone show struck all of a sudden...
I felt a bit weird... Well,I felt strange at first,then I thought,maybe one of my friends will understand.And I told my friend and I found out he was a huge fan of the show too!
"Haha, wow, this is awesome." And then I spent far too much time trying to figure out how to buy an Applejack figure and sneak it into my room without my mom or brother noticing. Fun times, yo.
Dunno. All I know is I was really depressed before it and discovering pone made my life not suck as much.
Okay, the guy next to keyboard could say that it's, like, cool thing to know 'bout. I dunno, really. Imma just stalliongradskaya pony.
I became a fan at the end of 2012. I think it was November. I saw some fan-created music like Flutterborn, Love Me Cheerilee and September. I thought they were pretty cool and to understand it better I went to go watch the show.
(EDIT: Oh jeez, I just realized I wrote an essay instead of just answering the question. Sorry!) It all started when I saw a pic of the Cake's kids on YouTube. I actually wasn't sure what they were at first (The photo showed them covered in sugar... Or something. I forgot.). After looking it over, I found that I liked what I saw (Although I kind of don't like the episode of Pinkie babysitting the kids nowadays.) and began to delve deeper into it. Eventually I decided the Apples were my favorite ponies (Even though I also really like pegasi.) and watched a bunch of analytical videos. Sometime later I was pulled away when a thing called Kid Icarus: Uprising came around, but the two have crossed over (toxically) a few times (Ex: Pretending Palutena (the Goddess of Light in Kid Icarus) the alicorn replaced Celestia. My 13 year old self was crazy.). So I'm just starting to come back into MLP now. I've even started to draw some OC ponies and plan to use them later on!
I don't know, I guess I just always was. I've been hopeful for new ponies to be good things pretty much since always. I had a fair few of the G1/G2 shows on VHS when I was a small child, checked out a couple of G3 episodes for nostalgia when it came out & it was just awful (I did get a couple of the toys though). When G4 came out I again gave it a shot for nostalgia but wasn't expecting much following G3... turned out WAY better than the original, better than most everything else on TV.
I wasn't shocked, yet I was surprised. I am a rather unique individual (or so says my therapist, my mental asylum attendee, my parents, my few friends on Skype, the people of the world whom I have wrong *coughsI'mkiddingcough*) so something this strange wasn't that differnet for me.
