|~ Commander Yammark|
Commander Yammark is one of the eight bosses from Mega Man X6.
Yammark was a Reploid created by Gate to lead a nature preservation team. During one of his missions an accident made him cause a fire that burnt a large portion of the forest. Though he was not accused of being responsible for the incident, someone sabotaged his flight systems during a maintenance check, which caused him to crash and die. He was later revived by Gate as one of his Nightmare Investigators, being put in charge of the Amazon Area. Having grown a distrust on the Maverick Hunters and Reploid researchers, he immediately attacks the Hunters when they reach him.
Yammark fights by using his dragonfly drones, which he can set up on various formations. He is the easiest of the eight bosses, as his patterns are very predictable and he takes considerable damage from the standard weapons. His weakness is the Ray Arrow.
