Yivel was a Brunali boy living on the Brunali homeworld. He was a friend of Icheb's before he was assimilated by the Borg.
When Icheb, freed from the Borg Collective, returned to his homeworld in 2376, Yivel was happy to see his old friend again and invited him to play a game of pala. Icheb couldn't remember the rules, but Yivel told him it would come back to him very quickly. (VOY: "Child's Play")
Yivel was played by actor Eric Ritter.
