MLP was also the very origin of my oldest sona (that evolved from a pegasus working in the Rainbow Factory (the mlp grimdark story one) into original species and setting etc), lore changed a lot but colors and some design elements stayed the same still for all those years i think it's also super easy to guess that my fave pony was Rainbow Dash, but from less obvious i also really loved Flutter Shy, Zecora, King Sombra, Princess Luna, Derpy and Spitfire (i REALLY disliked unicorns and alicorns overall btw) aside from that i remember being heavily into MLP fan stuff, Woodentoaster was my most favorite artist of all time, and i was spending a lot of time reading grimdark fanfics or searching for horror mlp games like my little amnesia (which i think it was a name for an amnesia mod), silent ponyville, story of the blanks etc, i'm not even sure if those last 2 were even real/public fangames lol (you can tell it was peak of my edgy era back then)
