Hm It's interesting that the only confirmed Vaccine type in the group is BanchoLeomon. The rest are either Virus (BanchoGolemon), Data (BanchoMamemon and BanchoLilymon), or Variable (BanchoStingmon). Though I think the BanchoStingmon probably counts as Viral as well given regular Stingmon is a Virus type isn't it?
