This is kind of a “deep cut” but, for those who can appreciate it, here is a lora of the boomerang faced Zeta as he appeared originally in the Kids WB show Batman Beyond during the second golden age of animation.
Notes:
Trained on NIA, intended for use with anime models. Use “zeta, robot” or “zeta, humanoid robot” to trigger him, “zeta” by itself will produce weird results. Should produce the likeness of Zeta 90% of the time. Incoherence dramatically increases the wider you make the picture. Making the image taller is a crapshoot, his spoiler boomerang head thing seems to lose its smoothness the taller you go. Denoising values for upscaling should be well below 0.4 in the 2.7 range.
As far as variability/versatility, your mileage will vary, I find it difficult to get him into different poses other than simply standing and looking intimidating. Using controlnet to pose him introduces issues with his spoiler since that is interpreted by the nn as a face.
Future:
If I can get a hold of the original episode, I could extract some high quality screen caps with a wider variety of poses to give the lora some more versatility. We’ll see.
