Kraitler

Kraitler is a snake dealer and the hidden secondary antagonist of the 2006 action/horror movie Snakes on the Plane.

History
Kraitler had been illegally gathering rare types of snakes from around the globe. He was hired by crime lord Eddie Kim to bring the snakes to Boeing 747-400 jet airliner South Pacific Air Flight 121 in order to prevent Sean Jones (who was escorted by 2 FBI agents Neville Flynn and John Sanders) from reaching Los Angeles International Airport (LAX) and testifying against him in a trail in LA.

He was eventually found by the FBI agents on ground lead by Agent Hank Harris and while attempting to fight back, he was bitten by one of his snakes. Harris extracted a confession from Kraitler who confirmed that he illegally obtained the snakes for Kim's use and after being given a dose of anti-venom, Kraitler was taken into custody.
