Of course she could wipe out all life on a planet with just her nuclear egg rapid firing while she was in orbit above it. The power would have to be upgraded to around 100,000,000 mt to destroy most life in a single go.

Nay. If one fired a volley of several dozen nuclear eggs, each with roughly 40mt to 50mt of power, the combined salvo would be a few thousand megatons. This would be more than sufficient to wipe most sapient life from a planet, plus the fallout of such a barrage killing the remnants over the next several days.
