One of the dessert-time jokes among Columbians involves a strange man who calls himself a "Master Thief," puttering around with a self-made jetpack. The most valuable thing he's stolen is a single burdenbeast. However, the fact that he made his own jetpack might mean that he really is a master.

A strange individual with a self-made jetpack. When blocked, will take flight for a short period of time.

Don't underestimate this self-proclaimed Columbian "master thief" because of his particularly funny, uncreative nickname; while the Jetman is very weak compared to the other bosses, he makes up for it with his significant HP and DIY jetpack (different to those used by Airborne Soldiers, Guerrilla Siegebreakers, and Ursus Assault Crossbowmen) which allows him to fly for 7 seconds in the event he is blocked, with a cooldown of 1 second from when the Jetman spawns and 25 seconds afterwards.
While airborne, the Jetman becomes an aerial enemy and has his speed increased by 50%, but does not attack and will be forced to land prematurely in the event he is Stunned, Frozen, or put to Sleep.
