After doing some study of Jubilee I found that her powers are (or WERE) far stronger than led to believe. She actually had the ability to detonate molecules on the sub-atomic level which basically meant she could cause nuclear explosions. She never took her powers that far. She came close but vowed to never use her powers at that level again.
Dazzlers powers are completely different. Her powers are actually similar to the powers of my character Treble. She can convert sound waves into light and energy beams.
