Jordan Cross (Joseph Cross)

• Blessed with Suck: Sees a vision of how people die when he touches them. He is often disturbed by the visions.

• Meaningful Name:
  Smallville wiki: Jordan's name may refer to the River Jordan in Asia. The Israelites "crossed the river Jordan" to get to the Promised Land after escaping slavery from Egypt. Since then, it has been a symbol for souls crossing into paradise after death.
• Power Incontinence: He can't turn his power off.

Alicia Baker (Sarah Carter)

• Achilles Heel: She can't teleport if she's touching or surrounded by lead.
• Back for the Dead
• Blondes are Evil: Or at least very Yandere-ish.
• Breakout Character: Was so popular with viewers she was brought back for two episodes in Season 4, and her actions set up a good deal of the show's mythos (by having her reveal Clark's secret to Chloe). Not bad at all for an Original Character.
• Clingy Jealous Girl: She becomes obsessed with Clark, hanging pictures in his locker, scratching out Lana's picture in his yearbook, and redecorating his loft.

• Temporary Love Interest
• Unexplained Recovery: Overcomes her insanity.

  • He also believe the meteor shower had corrupted Smallville. It's more or less true.
• Super Strength: He was able to hit Clark across the room.
• You Are What You Hate: Inferred. He has issues with meteor freaks blaming the meteor shower for bringing an evil to Smallville, yet he himself is one which may of caused him serious issues. However, it's never said directly that he acquired his powers from the meteor.

Andrea Rojas (Denise Quiñones)

Maddie Van Horn (Emily Hirst)

• Creepy Child
• Cute Mute: At first.

• Deadpan Snarker
• Elemental Shapeshifter: Into water.
• Evil Cannot Comprehend Good: She seems to enjoy ruining people's lives; that or she doesn't give a damn about anyone but herself and her career.
• Evil Counterpart: Played as Lois', especially in her second appearance.
• For the Evulz: At least some of her actions are simply because she's a sadist who enjoys inflicting pain. She certainly seems to enjoy all of her misdeeds though.
• Hoist By Her Own Petard: Tries to manipulate Davis into transforming and freeing her. Instead he turns and kills her.
• It's All About Me: She doesn't care about a single thing except for herself and is perfectly willing to destroy anyone's life for her own benefit.

• Kryptonite Factor: Electric shocks force her back into human form.
• Paparazzi: Works for a tabloid.
• Making a Splash
• Meaningful Name
• Punny Name
• Smug Snake

• Too Dumb to Live: Trying to manipulate an obviously unstable man with an obscenely powerful alter ego into doing your bidding isn't a good idea, to say the least.

Tobias Rice (Greyston Holt)

• Aura Vision: Sees normal people as red figures and meteor freaks as blue figures in a manner similar to infrared imaging.
• Blind Seer: Granted the ability to detect meteor freaks after being blinded.
• Disability Superpower: See above.

• Unwitting Instigator of Doom: Tricked into handing Chloe to Lex's secret lab where she is experimented on and painfully humiliated, and later almost killed.

Daniel Kim (Anthony Shim)

• Mind Over Matter
• Only Sane Man: Exceedly rare as he appears in the same episode with Tobias, making two sane meteor freaks in one episode. Three if counting Chloe. But then, Lex doesn't give him much time until his minions catch up with him in a "car accident". This may have something to do with this episode being directed by Michael Rosenbaum, Lex's actor, who always wanted Lex to be evil. Naturally, he would have to make meteor freaks more sympathetic to make Lex look bad. Also, it seems meteor freaks in general have becomes less psychotic after this episode.

Lowell Wilson (Juan Riedinger)

• Super Strength

Davidson (Richard Stroh)

• Ax Crazy: At least, according to Lex.
• Blow You Away: Being an extremely minor character, it is unclear but he appears to restrain Lana with air currents.

• Mind Control: Could control any meteor freak, including her own daughter, Chloe Sullivan.
• Power Incontinence: Most ironic indeed.

Wes Keenan (Tahmoh Penikett)

• Shock and Awe

Rudy Jones/Parasite (Brendan Fletcher)

• Adaptational Badass: A mild version. He doesn't need skin contact to absorb powers and it is done in a second. He could also give them back and keep them longer.
