A mad scientist who creates a device that cancels out suction cup man's powers could be a great villain. He could be jealous of suction cup man's abilities and wants to prove that his science is superior.
A plot idea could be that suction cup man is part of a secret society of people with strange powers. His suction cup ability is initially seen as a joke by the others, but he ends up being the key to solving a mystery that threatens the society. He might also use his suction cups to communicate with some sort of underwater creatures that can only be reached by adhering to the walls of their underwater lair. Additionally, he could be in a world where gravity is changing constantly, and his suction cups are the only way he can move around safely.

It could also be about the grandmother's wisdom and how she uses it to deal with this 'black destroyer', whether through trickery, strength, or some other means.
