Kaiju and Mecha Universe and Skins

So I’m a huge fan of League of Legends story and writing. It’s writing is one of the influences that got me into writing. I’m very intrigued in the Mecha Universe and was wondering why no Kaiju have been added. We have plenty of Mecha (Sion, Malphite, Aatrox, etc.) but only one official Kaiju (Crabgot). I understand developing these skins and stories must take work and was wondering when we might see them. I’m a huge fan of the Mecha skins and their inspiration (Pacific Rim) and am looking forward to hearing about the progress on the Kaiju line. Any thoughts on when and what you’d like to see? Mainly because hardly anyone seems to be talking about the skin line.
