Ugly Bastard is a term describing a male character in pornographic art drawn to be extremely ugly, and often acting in a disgusting or reprehensible way.
Ugly Bastards are most often seen in hentai, typically as middle-aged human men, and sometimes are drawn as faceless males; less commonly, ugly bastards are fantasy monsters such as goblins and orcs, or monstrous anthropomorphic creatures - usually boars or pigs. In appearance, Ugly Bastards are some combination of overweight, hairy, and overly sweaty; human ugly bastards are often bald or balding, having a piggish face with beady or empty eyes (if their eyes are drawn at all), and a bulbous or exaggeratedly large nose (sometimes with snot running from the nostrils).
The "bastard" part of the term describes the behaviour of these characters, who often are shown humiliating, dominating and usually raping conventionally attractive female characters. Ugly Bastards are also a common part of cuckholding scenarios (in the form of a hentai genre called netorare). Even if they're not doing anything worthy of "bastard" in the image, if the character is drawn in the style of an "Ugly Bastard", the tag applies.
Note: An overweight male is not inherently an Ugly Bastard:
- Ugly Bastards are drawn specifically to elicit disgust from the viewer, they're exaggeratedly ugly or monstrous
- An Ugly Bastard will almost never be depicted in a solo image
- Ugly Bastards are rarely given any kind of characterization in a comic featuring them
