A young colonist at a remote deuterium mining settlement who is eager to stand up to the Klingon raiders extorting his people and joins the defence organised by the Enterprise crew.
Maklii is a young man living in a small deuterium mining colony visited by Enterprise in the episode Marauders. The settlement is being bled dry by a band of Klingons led by Korok, who arrive regularly to seize most of the fuel the colonists extract.
Where the colony's leader Tessic counsels submission, having seen what resistance cost in the past, Maklii is impatient to fight back. He is quick to accept Jonathan Archer's offer of help.
Maklii trains with the Enterprise crew in marksmanship and hand-to-hand defence and takes part in the ruse that lures the Klingons onto the deuterium field, which is then set alight around them, driving the raiders away for good.
