lv 1 Zorua, which i evolved and trained to lv 100. Sadly I traded her to a friend, who was desperate. Now i've trained my second Zoroark to lv 100. I also have my Serperior, now lv 79. I also recently traded for a shiny Ninetales lv 100, and is soon becoming one of my dearest as i use it almost 24/7 in random macthup.
I do remember my Gengar and Weavile though(Now deleted form 4th gen)
