Here's a couple of my favorite Elementals covers.
The two issues showcase a couple of characters that I really like Thor & Ghost Girl/The Haunting. As far as power sets go, I'd give Thor the following:

Origin/Background: Janet Brown was born January 31st, 1898. She lived an uneventful life and became a librarian Wichita, Kansas. In 1929 she came to the notice of the sorcerer Saker, who realized she possessed a great amount of darkforce. He killed her and performed rituals on her body because he was curious about what powers should would manifest, but was disappointed by her abilities and found her too difficult to control. He placed her in storage in his headquarters on Nacht Island where she stayed until the U.S. government took the island in 1984.
She was recruited into Strikeforce America alongside Commander Chaos, Kid Chaos, Jumpstart, Skyscraper, Doctor Thunder and Microman.
Notes: The Haunting is an actual ghost, with the ability to turn invisible and create realistic illusions. The illusions are so horrifying that her victims literally want to rip their eyes out.
