Stormforce
was born with certain powers of weather control and manipulation as well
as superhuman physical attributes. However, her powers really took off and
expanded when the thunder god Thor appeared to her in a dream and
bestowed upon her the mantle of the storm (in his own image
of course).
Stormforce always possess weather control and flight powers. By invoking the name of the storm god, she instantly transforms into a real powerhouse and wields a "mystic hammer" (really just a manifestation of her power) which lets her cast lightning bolts. She can also throw the hammer or hit a target with it.
