So I was thinking about Jade’s God Tier powers recently. It appears that she can alter the size, speed, and location of spatial objects. In Cascade she demonstrates this on a large scale, but there’s no reason why she can’t do it on a micro scale as well.
For example, heat is just molecules moving very quickly. In theory, she could take exception to someone and boil their blood in their body. Problem solved.
Then I started wondering if she could affect subatomic particles. And that led me to this:
Jade has been associated with radiation. Her associated object is uranium. Her shirt occasionally bears the symbol of an atom.
The basis of a nuclear reaction is formed through nuclear fission, when the unstable nucleus of an atom is split. The energy released from this fission is harnessed into power, a bomb, etc. This usually takes a lot of high tech equipment. With Jade’s powers, she could just make it happen.
Long story short - Jade has the power to make a nuclear bomb. And she probably wouldn’t find it difficult.
