Toymaker's Medical Book: King Bumi Syndrome

For the first entry on our Toymaker's Medical Book, we have King Bumi Syndrome. King Bumi Syndrome is a dreadful and usually fatal event that occurs when a toy company refuses to make the lead female characters in a toy line and instead makes a signifigantly less popular male character in her place. Named for King Bumi from Avatar the Last Airbender, who was made instead of Katara and ended up killing the line. 

King Bumi was only the most notable case. Other fatal cases include:

* In Bucky o Hare, we got the human kid and a generic toad air marshall instead of Jenny.

* Naruto was devoid of it's female ninja and instead had a couple fairly obscure characters in it's mix. Plush and statues of the females were eventually made by other companies, but the toys had died off.

* One Piece, an anime about pirates, ended up making none of it's female crew.

* Speaking of Pirates, Pirates of Dark Water made background characters Zooloe and Joat, but no Tula.

There were two lines that succumbed to this even though they probably would quickly  die anyway.

* Stone Protectors made no Princess Opal but made Sucker Puncher and Tackle Jackal.

* Super Mario Bros by ERTL did not include a Princess Daisy toy in it's line up, but instead a Goomba. 

There have been non fatal cases, but this is usually when the line is for preschoolers.
