"Enemy's Pride, Chapter One: Lie of the Beholder"
After falling down a well while fighting the mutants, Lion-O does not quite seem the same. For starters when he maims the ear of Slythe as he banishes them, he gets looks of surprise from all members of the Thundercats. Later, WilyKat and WilyKit overhear Lion-O plotting the downfall of the ThunderCats. When they try to let the others know, they are interrupted by the announcement that WilyKat is to become a captain in Lion-O's mountain guard.
