Sol's Hammer

The Sol's Hammer was a partial dyson sphere designed by Tony Stark as a fallback plan for the crisis of the incursions by weaponizing the power of the Sun.^[2] At a point before the Builder War, it was operating at 0.008%, enough energy to power a moon.^[3]

When a Shi'ar fleet attempted to destroy the Earth in order to put an end to the incursions, Iron Man used Sol's Hammer to slaughter the invading force, but in the process, Sol's Hammer was destroyed.^[4]

The schematics of Sol's Hammer eventually fell in the hands of Damage Control since the company also operated as an archival unit for government-contested technology that belonged to missing, incapacitated or deceased individuals. Despite Tony Stark and Reed Richards going to great lengths to ensure that their technology did not fall in the hands of other parties besides each other, Damage Control gained the rights to Sol's Hammer data after Reed was missing from a prolonged period of time and Stark was incapacitated. The remains of the Sol's Hammer were later retrofitted by the Orchis into the Orchis Forge.^[5]

• Reed Richards was the one who named the Sol's Hammer.^[2] Presumably, Reed was inspired by Sol's Anvil, which was built by the Interdimensional Council of Reeds and was used by Reed-616 during the conflict against the Mad Celestials.^[6][7]
