I've been a big Pokemon fan my entire life, though lately I've fallen off of it due to feeling discontented with Nintendo-adjacent properties as a whole (yes, I know they're Game Freak, but they're adjacent). I more prefer the world and characters at this point rather than the actual games, though I'm not opposed to maybe re/playing one of the older titles.
It all started when I was born honestly, Indigo League would play on the TV and I was enamored with it. I went on all the fansites (marilland, serebii, ect) and loved learning more about my favorite series. I was finally allowed to own my own game in 2006 with Pokemon Pearl. Since then, I've played Soulsilver, B/W & B2/W2 (I don't remember which one), X, Ultra Sapphire, Sun, Ultra Sun, & Shield. I've also played many spinoff games, including the first and third in the Ranger series, Mystery Dungeon: Explorers of Sky, and Battle Revolution
Honestly, after everything I've played, I still prefer the world and feeling of Gen 1 and maybe a little bit of Gen 2. I like to joke that I'm a "genwunner", but I actually do appreciate the other Pokemon games. I just remember the times I watched the anime as a child and like reminiscing on when there were only 151 in the series. The Gen 1 games are a bit of a mess, but if anything it makes me appreciate them more, as it adds to the underdog story of Pokemon's creation

My favorites are Pikachu & Rattata!
Pikachu is pretty obviously the mascot, so that might be a stereotypical choice, but there's a
reason it got picked as the mascot over Clefairy. Pikachu's shapes are so strong, it's cute and recognizable and lovable, and it's some sort of rodent, which means it's good by default. I have fond memories of watching Ash and his Pikachu bond and face the world together. Just an incredible Pokemon
I like Rattata a little less than Pikachu, but it is a little rat just like me, so I think you can see why I love it


These are the favorites (and species, actually) of various members of our system, but they're not really planning on posting on this forum as I'm really the one who holds the video game interest. I still wanted to include them, though, cause I love my headmates :]
