Story arc
Lactis is one of Jan's subordinates along with Melisse, Erich, Mikhail and the combat support robot Bugs. He assisted him during his investigation of Voyager. Lactis is close with his colleagues and dedicated to seeing the mission through to the end.

Unknown to Lactis, he contains a program called "Canaan" which is responsible for searching for humans that have a particular factor within them. This fact is known to Wilhelm who discusses it with his subordinate. Lactis is unaware of this program, including when chaos speaks to him, telling him that he must protect "Canaan" with all his strength.

When the investigation into Voyager is shut down, Lactis is not arrested as his colleagues are. This enables him to activate Bugs and they help Jan and the others escape. Lactis is present for the final confrontation with Voyager and witnesses Jan's suicide. He survives the incident and is recalled to Vector Industries afterwards, with the public explanation being that he had a "defect" in his central nervous system.
