A little while ago, when watching Pacific Rim, I remembered how Gullermo Del Toro had suggested the possibility of a Kaiju-Jaeger hybrid in Pacific Rim 2, and this is what I came up with.
Practically, I imagined this Kaiju's physiology being modeled after Gipsy Danger, and wanted to create the antithesis of the pilots by combining attributes of Knifehead and Onibaba, the two Kaiju that had cost both Raleigh and Mako their families... obviously because of the whole "organic mecha" theme of the Ante-Jaeger, Onibaba's crustacean biology is much more obvious in the design.
I can also imagine, with some editing, making this into an original character, something that'd fit into a spin-off of the AdventDestiny series [he just looks like one of those classic Tokusatsu monsters!]
