My personal faves. As you may deduce, I have a bias towards archers

5. Vet Hawkeye from Ultimates. Not the best range, but 3 and an 11 attack with Ultimates TA.
4. Vet Green Arrow from Cosmic Justice. For 50 points, you get a figure with 10 range, 11 attack, 2 targets, Stealth and RCE.
3. Thomas Oscar Morrow. I love this guy. RCE for three clicks and then picks up Support for only 37 points. He has saved my butt on more than one occasion. He even took down the Anti-Monitor!
2. Vet Hawkeye from Fantastic Forces. Transporter movement with 11 attack, 3 targets and 3 damage plus RCE. T-bolt him to Batman Ally or Ultimates or whatever you need and have him carry an enhancer for a possible 6 clicks of damage at 10 range.
1. Unique Arwyn. I am in love with this chick! With Running Shot, Energy Explosion, Willpower, RCE and 10 range, she is awesome. She has RCE to her death. She is nasty by herself. Give her Trick Shot and Armor Piercing and she's devastating!

No love for Ultra-man? I like dishing out 7 clicks of damage first shot.

I haven't heard the cast, but Vevi names some favorites.

I am partial to the E, myself. So much cheaper that he can afford an LE Atom as a Trick-Shot sheild who can also pump his damage, range or AV as needed. ICWO for each means that shild has a 21 D and GL has another +1 to add somewhere.

It's not the same thing as a GL Tank, of course, but it's cheap and it won me a few tournies.
