Minch was a Jedi Knight of the Old Republic some seven hundred years before the rise of the Galactic Empire. Of the same species as Jedi Masters Yoda and Yaddle, Minch joined a group of Jedi Knights to stop a group of Dark Jedi on a rampage in the Bpfasshi star system. Pursuing the one of the Dark Jedi Knights to a Commerce Guild space station, Minch cornered the pale-skinned Knight at the end of an empty corridor, and the two engaged in a fierce lightsaber battle during which Minch was bested. Before the Dark Jedi could land a killing blow, the rest of Minch's team arrived as reinforcements.
The Jedi demanded the Dark Jedi to surrender and tell them where his master was hiding. Rather than betray his master, the Dark Jedi fell on his lightsaber telling them nothing. After this, Jedi Master T'dai, leader of the operation, received word of an unauthorized launch from the space station's docking bay, and Minch and the Jedi quickly got to their ships. Pursuing the ship as it made a run for escape, it headed for the Sluis Sector and the planet of Dagobah. As Mich followed, he was ordered to stand down to wait for backup from their accompanying ship, the Takara.
However, Minch feared the Dark Jedi Master would use the planet to escape yet again and he disobeyed an order to follow him. Storms in Dagobah's upper atmosphere disabled Mich's starfighter and he crashed into the swamps of Dagobah. Minch pursued the dark master through the dense jungles of a planet and into a cave where he confronted the red-robed figure. In the cave, the Dark Jedi preyed on Minch's fears and used the Force to project an illusion of himself as a giant. As Minch attacked the illusions persisted and Minch became more and more terrified.
