It is unclear where joke characters came from, but it is likely that Dan Hibiki
is the most well known. Joke characters, like Dan, are often mockeries of other video game characters, movie characters, or even real people. However, they are not restricted to being jokes, often comic relief characters can become a key part of the story, like Johnny Sasaki
from the Metal Gear
series. All in all, the key role joke characters provide is an interesting commentary, lots of laughs, and a unique addition to the existing storyline.
