Welcome welcome to PC, Potato! ...that's a silly nickname, have anything you want to be called? :o
Groudon is one of the best legendaries, I adore the third generation legends and they'll always be my favorite duo from Pokemon. If only Groudon and Kyogre got bigger roles in a movie but alas. :( Well, maybe in the future! Are you into the third gen? If you are we recommend checking out the Advance Generation Gaming board to discuss those games there. You'll definitely have a blast exploring!
Enjoy your stay and be sure to stick around, all right? If you're into the TCG then definitely pop by the Pokemon TCG board here on PokeCommunity, too, as we love having more card game fans around. I don't play but love to collect them for the pretty artwork aha.
See you!
