Midvalley the Hornfreak is the 11th Gung-Ho-Guns member.
Midvalley the Hornfreak was originally a member of three-man band that used sound to perform assassinations for money. Millions Knives discovered their talent and intended to press them to join his Gung-ho-Guns. The other two band members immediately refused and attempted to kill Knives, and were quickly executed. Throughout his service as a Gun-ho-Gun, Midvalley hoped to betray Knives and Legato Bluesummers to escape.
When he is sent alongside Hoppered The Gauntlet, they plot to disobey orders to torment but not kill Vash the Stampede, to allow Hoppered to get his revenge on Vash and for Midvalley to disappear in the aftermath. While Hoppered attacks Vash, Midvalley the Hornfreak and Nicholas the Chapel fight a secondary duel. Midvalley's and Hoppered's plot ultimately fails and Legato reveals his knowledge of their betrayal. Legatto then executes Midvalley by commanding the giant to smash Midvalley with the giant's spinning motorcycle tire. Afterwards, he uses Midvalley's dead body to try to execute Hoppered as well. Though Vash protects Hoppered from Legato's attack, Hoppered later succumbs to his wounds and passes away. Vash and Woflwood bury Midvalley and Hoppered next to one another, setting Midvalley's saxophone on the gravestone. Wolfwood remarks that he feels no sympathy for Midvalley's failure to escape his doom.
Midvalley the Hornfreak is a violent musician who is able to use his saxophone, Sylvia, to synchronize sound waves with pain, causing physical damage. He introduces himself as the Eleventh Gung-ho Gun and is the last to challenge Vash The Stampede. After Vash disables his saxophone, Midvalley kills himself by overloading the jammed machine gun installed in the saxophone.
- In the manga, he plays a baritone saxophone, but in the anime it's a futuristic-looking alto saxophone.
- "Hornfreak" is most likely a reference to how musicians call wind instruments the generic term 'horns.'
