He is scary,strong,brave,persistent and evil. He does all that he can just to make his promise to kill Dirk The Daring. He trapped the princess in a haunted dungeon full of monsters and creatures like minions.
In the first game, he imprison the princess in a crystal orb. According to the manual of the 8-bit version, Singe commanded Ethelred to surrender his kingdom before sunset.
Daphne appears in the final level of the game, giving Dirk directions to use the magic sword and slay the dragon.
In the NES version, Singe will shoot fireballs and summon smaller dragons when being fought by the player, however, this version is extremely hard, thanks to the slow animations and buggy gameplay, another reason is that Singe's attacks usually do very high damage or instantly KO the player. It is advised to attack from a far distance and duck and jump from projectiles, and also attack the dragons that Singe summons.
Singe don't appear. However, his role in the precedent game was revealed to be the evil wizard Mordroc's minion.
According to this reboot game, Mordroc is the main villain, and Singe is only his sidekick.
