Partners in Danger Chapter 10: Lizard King - S4-E10
Plot hole: When Debra and Margaret arrive at the underground arena with the device that can revert the humanoid lizards to their original forms, they lose control of the device and it ends up in the hands of Ghila, who monologues that the humanoid lizards' existence was an accident and that she will use the device to return them to being regular lizards. Ghila had never seen this device before, nor did anyone tell her what its purpose was, so there's no way she could have known it was designed to reverse the mutations.
Answer: In the comics, Hobgoblin's true identity was kept a mystery for a long time intentionally and while many fans deduced it was Kingsley, and creator Roger Stern was leaning that way, Stern left the series in 1984. In 1987 Hobgoblin's identity was revealed to be Ned Leeds and then Macendale became Hobgoblin. It wasn't until 1997 that Sterns wrote the mini-series "Hobgoblin Lives" and retconned Kingsley as the original Hobgoblin.
