Planet of the Apes #33

Derek lands on the Island Avadon and is immediately confronted by an ape in a suit of armour. This ape is Sir Gawain, who takes Derek to the medieval castle of King Arthur. The castle is occupied by apes and talking humans -- all peacefully. Derek claims to be a powerful wizard and offers his services to the king. Derek kills a dragon (giant lizard). King Arthur makes Derek a knight. Sir Gawain challenges Derek to a battle to the death.
