Jeff Palmer is the very protective brother of Amy Palmer.
His parents worked on the staff at the Luthor Mansion. He found some strange green roses on the grounds of the mansion. He studied the meteor rock-mutated roses, extracted their oils, and created a cream that rendered him invisible.
Powers and Abilities
- Invisibility: Jeff managed to make a cream out of the oils he found in kryptonite infused green roses, which makes him invisible. Jeff stated that while normal plants absorb light the oil of these roses refracted it. This invisibility is achieved by Jeff rubbing the cream all over his body and he becomes perfectly visible after removing it. Jeff´s invisibility through these kryptonite infused roses allowed him to be almost undetectable by Clark´s x-ray vision.
Jeff's sister was obsessed with Lex Luthor and jealous of his current house guest, Victoria Hardwick. Jeff used his invisibility to vandalize Victoria's room, making Lex think there was a "ghost" haunting his mansion, but when she still didn't leave, he tried to drown her in her bathtub. One day after Amy had another jealous attack he went for Lex, attacking him and shouting at him to choose Amy over Victoria. Clark arrives just in time to see Lex hurt on the floor and manages to push Jeff into some construction scaffolding where a bucket of paint fell on him, making him visible and knocking him unconscious. After his battle with Clark Kent, he was taken away in an ambulance in need of some "serious therapy."
- Jeff is similar to DC Comics supervillain, the Mist, who invented a chemical that allows for invisibility.
