General Tal Attacks Flash

The antidote administered by Dr Zarkov restored flash Gordon’s memory. Then the Doctor and Dale Arden told Flash what had happened while he was under the spell of the wicked Queen Azura. Zarkov persuaded him that he must take over the Blue Magic Land just as he had taken over the other kingdoms so Flash went in to see Azura who under the spell of her own forgetfulness failed to recognize him. Azura accepted Flash’s claim that he was King and at his request ordered the entire army of the Blue Magic Land to pass in review before him.

After conquering the men with a magic torpedoe Flash Gordon was puzzled by the fact that Zarkoff running out to meet him with upraised hands called him “friend”. Queen Azura assured Flash that it had been a trick to disconcert him then she ordered the frozen prisoners be removed to the palace and that good care be taken of Zarkoff particularly. When Dr Zarkoff was brought back to life he asked for Flash but was told that Flash was under the spell of the queen’s drunken forgetfulness. The Dr Zarkoff was taken to the kitchen where he was reunited with Dale Harden who he comforted by his promise to use his scientific powers to aid them all. Stun by the lashes of the electric whip Zarkoff saw an opportunity for revenge and escape.
