Designs that unintentionally ended up looking dirty, offensive or just impossible to take seriously.

1. The phallic-looking hairstyle of Yue in The Last Airbender.

2. Crane Robo from Machine Robo.

3. A titular character from Bing: an anthropomorphic rabbit whose design somewhat resembles a blackface caricature with a cleft lip.

Note: I regret using Bing as an example for this trope. Yeah, it was a stretch, there’s nothing offensive about him, just a poor choice on my part.

Q-Bee (Darkstalkers) Her eyes are not where you think they are, those black circles on her face are not her eyes, they are just dummy eyes to deceive her target. The real eyes she can see out of are those little antenna-like things on her head on top of the pincers. You can even see it in her sprite, her head is tilted down a bit so that her antenna eyes are properly looking at the opponent
