User blog comment:BannedLagiacrus/Monster Appreciation Week: Blue Yian Kut-Ku(4th Gen)/@comment-4090136-20160113030702

I don't think that there's any reason for Blue Yian Kut-Ku to exist. It doesn't add any new elements, attacks (or at least not noticable ones), mechanics, or anything. All it does is get a bit angrier.

Yian Kut-Ku really needs a new subspecies.
