Hey there Master! Welcome welcome to the forum!! :)
We have an awesome dark type fanclub
right here that you can join, so go ahead and fill out the registration form on the first page! Dark types are super popular and I love them as well. Umbreon and Mightyena are some of my favorite darks, too bad Mightyena isn't the best stats-wise though. Still love to use it. :D; While you're at it I'd also recommend looking around the other clubs in our Pokemon Clubs board, there are probably many other ones that'll catch your eye there. One of our most active clubs is the
Riolu & Lucario fanclub as well.. another place you'll probably really love, being a Lucario fan. If there aren't more clubs open that you'd like to join currently available, you can look into making your own if it hasn't been reserved yet! Owning a club is really one of the most fun things to do here on PokeCommunity.
Aaaand there's also the
Battle Center for battling that you can explore anytime. You'll learn a lot about battling there; we have some guides at the top of that board for members looking to get into competitive battling. I'm sure our battlers would love to practice with you anytime, our battling platform of choice is Pokemon Showdown so you should definitely check that out when you can. It's one of the forum's most active offsite chatrooms and they welcome all new members looking to get into the swing of things.
Hope you have an amazing time posting around here, Master! Be sure to let myself or another
moderator know if you need any help. I've been a Pokemon fan since I was a kid too so we already have some things in common.. we'd probably make good friends. My profile is open if you ever want to chat.
See you around!
