Recreated, not traded over? You couldn't borrow a gameboy and put her in the next game? I understand with Amy the Dewgong, but Sapphire and emerald are fully compatible. I don't recreate. I don't trade much either, I just make original teams and don't dwell on the past if I can't get a poke from it's orginal game (speaking of doing so, Diamond's Migrate function is absolutely wonderful, without it my beloved Mew would be stuck in the 3rd gen forever)Hoo boy...I have lots of favorites, but I'm going to go with Zelda, my faithful Gardevoir on Sapphire. She's usually the staller when a Pokemon I need falls in a tough battle. But she really came through for me when I recreated her for Emerald...I would've never gotten a Mind Badge for the first time without her help.
Coming in second is Amy, a lv. 94 Dewgong I owned on Silver years ago. She was the closest I came to a lv. 100; and I really hope I can recreate her someday.
