For days, Gunther the Gumdramon was waiting for a special package in the mail. When it finally arrived, he wet his diaper in excitement. He tore the package open and found his prize, a bottle of FOY water. It was not just any old bottle of FOY water, though. When this FOY water is drank by a Digimon, they will Devolve. Gunther immediately chugged it and waited. He then reverted to a Chibimon/ Demi Veemon. He playfully flailed his legs around helplessly in his now too big diaper. Gumdramon actually doesn't have a trainer form, but I saw an evolution chart made by a fan who suggested a Chibimon would be his. And that thing on his diaper tape is a loin cloth, he too likes Harems.
