Watching lions hunt, the trends are quite obvious. The primary reason that groups of lions are no more effective than two by themselves is that typically only two lions do the actual hunting. They all make a show of hunting, but in the cases I watched, in several different prides, there were always a couple females that were the most aggressive and took the lead. The others hang back for the hard part then rush up at the end after the worst danger is over. Their primary goal is to be at the kill early so they can eat, not to actually help. Field studies have confirmed that lions do not seem to keep track of this and punish slackers.
Character synopses, histories, and relationships are sourced from The Lion King , The Lion King 1 1/2 , and the hardcover children's book A Tale of Two Brothers released in 1994 by Disney, written by Alex Simmons. This book is not strictly "canon" anymore, in that some of its content (namely the cub Kopa, Simba and Nala's son) has been contradicted by the release of The Lion King 2: Simba's Pride . However, its accounts of the events prior to the beginning of The Lion King with regard to the origins of Mufasa, Scar, Zazu, and others, remains uncontested. Therefore it is still considered "canon" on those points.
This site shows only the principal named characters from The Lion King . For an authoritative listing of all canon characters from all the Disney movies, TV shows, books, and comics based on the Lion King universe, see the TLK Compleat Character List compiled by Criswell.
