Another picture for Agumonofalchemy ‘s wiki. This one portrays the first meeting between Syrus and the Alchemist. This was before Syrus got his standard wardrobe. Back then, he only had a green cloak (not pictured), a blue scarf, and this normal disposable diaper.
Alchemist was dressed in a cursed diaper that changed him into a plushie, where Samantha the evil Gatomon treated him like a doll, hence his girly attire.
