Greg Gilday is not the most imaginative idea for a superhero to come down the pike. As stated on the splash panel, "Scientist Greg Gilday, on his deathbed, discovers a revitalizing ray which gives him new youthfulness and superhuman strength and speed..." Then he puts on a green shirt and a diaper and goes out to "abolish evil." Not content with that, he then "subjects" his pretty assistant to the same ray and she, too, "becomes imbued with superhuman powers." "Look! Up in the sky! It's...it's...Greg and Joan!!!!"
