I heard a news item on the radio while driving to work today about an experiment involving the use of cells to improve hearing for aging ears.
How is this relevant to the lovely Drura?
The cells were 'delivered' to the ear in a 'Trojan virus'. The virus lacked any disease-causing capability, but was the 'introduciton' medium for the specialized cells.
Add a thousand years and extrapolate.
With Brainy's aid, Drura'd be capable of just about anything.
Those virus/disease powers could work well with the abilities of Sun Boy, Chlorophyll Kid, Gas Girl, Kid Quantum, Chameleon, Umbra...
Drura could and perhaps should be at the top of the 'powers' heap.
Bring her back!
