@SpeedForceSpider: What can she do?
Gemini punches are equivalent to 6.87xE41 joules which is the power required to destroy a star.
Reasoning why is because at the end of his death he was capable of piercing his own cloth with his fist (Augmented by Cosmos and Gold Cloth), let alone speed blitz the fuck out of two other Bronze Saints who were already on par with the likes of Leo Aiolia or Virgo Shaka.
He can also warp his enemies in dimensions that have their own planets and stars, dimensions that move at the speed of light as I can recall from the fight between Gemini Deftros and the Time God.
Also, Gemini Saga is a galaxy buster at an atomic level and unless Nono has Galaxy durability she won't last against the might tyrant.
