Kullervo fits too well with the aesthetic of the rest of Duviri (especially the conservation animals) to be AI-generated. His base helmet is also an allusion to Thrax.

With that being said, I think the reason he seems AI generated is that he’s colored differently than other warframes. In order to match the duviri aesthetic, he has more blending of colors and less color separation, which is fairly common in AI stuff.

I like the design personally, but I kinda get where you’re coming from.
