|Game(s)||Monster Rancher Battle Card: Episode 2|
Master Oswald has been a part of the Retro Members since he was a kid. This battle card group believes that the only reason for using battle cards should be to train to become a full-fledged monster breeder. Unfortunately, Oswald holds so stubbornly to that belief that when he sees the trend of card breeding for monetary gain and fame taking hold, he stops playing altogether. This puts quite a bit of pressure on his daughter Elizabeth and his apprentice Ryan to do likewise, even though they don't agree.
Oswald has an intense dispute with Cue when he finds out that she is only a battle card breeder, but seems to respect you more when he finds out you play cards and raise monsters. After you beat Ryan in a card game, he and Elizabeth convince Oswald that his philosophy is wrong, and he decides to re-think his position on battle cards, even saying that he might change part of his teaching style.
