Ookla is a member of the Mok species, a leonine humanoid with fangs and yellow eyes. As a Mok, Ookla has great strength, usually fighting by ripping up a nearby sapling or piece of wreckage to club his enemies. On a few occasions he is shown to use a longbow that fires a type of paralyzing arrow. However, he is also the most likely of the heroes to charge right into an enemy attack or to be enraged by unusual nuisances or threats. Moks dwell in their own territory, ruled by a king; they fear and hate water, preferring to face overwhelming odds in battle rather than wade through a stream to escape.
