It's a flash based, superhero generator based off Bruce Timm/DCAU's designs and artstyle. Just for kicks I attempted to do the strawhats with this generator. Some came out pretty good.
Yes Sanji's "eyes" are backward, couldn't be helped. The generator is still WIP and so I tried to make due. I also did a couple of villians:
There were some alternate ones I made not in the group shot.
Robin in her All Sunday outfit.
Robin in her G8/Movies 4+5 Outfit.
Feel free to post your own attempts
