A young boy living in the small alien mining settlement that Enterprise helps to defend against Klingon raiders, who attaches himself to Trip Tucker.
Q'ell appears in Marauders. He is one of the children of a colony of deuterium miners whose output is being taken season after season by a band of Klingons led by Korok.
When Enterprise arrives to trade for deuterium and Tucker sets about repairing the colonists' pumps, the curious Q'ell follows him around, asking questions about the ship and about engineering, and Tucker lets him help.
The boy is part of the reason the crew decide not simply to leave, and instead teach the miners to stand up for themselves. He is kept out of harm's way when the colonists lure the Klingons onto the deuterium field and drive them off.
