Mordroc appears in some levels of the game to taunt Dirk the Daring, as in the Prehistoric era and in Ancient Egypt, appearing as a mummy after Dirk thought it was Daphne.
In the final level of the game, Mordroc puts the Death Ring on Daphne's finger, which transforms her into a monster, but she is saved when Dirks gets the ring off her and throws it to Mordroc. He turns into a bloated monster who gets killed soon afterward by Dirk's sword.
According to this game, Mordroc is the main villain, and Singe is only his sidekick. He was imprisoned long ago, after being defeated by magic arrows, and his minions took the Dragon Essences for themselves. It was him who ordered Singe kidnap Daphne. Mordroc also impersonated Daphne, persuading Dirk to get the Dragon Essences back. At the end of the game, he reveals his role but Dirk defeats him again with the magic arrows. Mordroc then turns into a wyvern.
