9.7/10. Hands down the best super heroine movie ever made. I know it's been torn to shreds by many but I disagree. Helen Slater possesses a charm that makes you love her instantly. It's good without needing Superman, a superhero origin doesn't need its big brother necessarily. Supergirl was the first and best super heroine movies still. I think it should be viewed more favorably, like a back up quarterback. She's still good in her own right. Go and watch this with an open mind. Helen Slater is one of several unfairly overlooked actresses of the 80's.





Answer: The Omegaahedron is the power source for the whole city. It supplies the air, the dome that protects them, the lights, and the machines they need to survive.
The question was why would Zoltar need permission to use the Omegahedron, not what it could do.
