When the USS Voyager traveled through the void, they met Emck
when he used spatial charges to flee some aliens holding
Voyager. The Voyager crew later found out (from one of the
aliens) that Emck was dumping contaminated antimatter and tried
to teach him ways so antimatter used by the Malon would not
caused byproducts. Emck dismissed this, noting that he would
lose his job, along with his crew. Attempting to use the spatial
vortex in the void, Emck attempted to stop Voyager from
destroying the vortex. With assistance by the Night Aliens, the
Malon export vessel was destroyed and Emck was killed when the
Night Aliens took down his ship's powerful shields, allowing
Voyager to destroy it.
