Your username and avatar are both pretty awesome. Welcome to PC, Colony! :3
Oh ghost types are so so awesome. Ghost, electric, and grass are my personal favorite types. We have a
ghost-type fanclub open for members to join, so you should stop by! n~n Now that I'm linking it I can see I haven't joined it myself yet, which is a bit surprising haha. Gengar is probably the coolest ghost, though I'm highly biased towards Banette since it was my favorite Pokemon to use in Sapphire.
There's also the wonderful
Battle Center that you can stop by anytime! Pokemon Showdown is our battling platform of choice so hopefully you can take a gander at it sometime if you're looking to get involved in the events/battles our members host. The BC has been quite lively lately so it's always wonderful when more new members show interest in battling. I'm pretty new to it but it's pretty fun regardless, especially since there are so many different kinds of battlers there. ^^
...and, of course, there's the
Roleplay Corner for all your roleplay-related needs! Another great section that's quite popular among the members, so you can stop by there whenever if you're interested. All-in-all, I hope you have a wonderful time on PC okay! Remember to read the main forum rules as well as the individual section rules to get an understanding of how things work here. Haaave fun~
