The Authorititans
The Deadly Dozen
Tim winning is a no-brainer.
I almost voted for LV just because she went all PowerPoint on Ari's ass. Just kidding.
This was actually a very tough choice. Yes, Alice can take the magic from beings outside the Panoptichron. Doesn't matter if they're in another universe. If accessing other universes did matter, then the Flash's wouldn't be able to use the Speed Force in Marvel locations. They can, so it doesn't matter. (This was settled way back in season 2, I think. Maybe season 1.) Could she take Aztek's helmet? Yes, it looks like it. If it has magical elements she can take them all. Can she steal Aztek's power since he's a Middleweight? No. Unless Aztek attacks her first, or Ari's ubers are down, she can't.
Of course, this still means Alice can fight Supes or the Surfer powered up by someone else's abilities like, say, Dr. Fate. This also means Aztek is still able to fight fully powered himself. So it's still a 5-5 match. And I think it'll be down to 3-3. Alice/Thorids/Byakko vs. Surfer/Supes/Aztek because Byakko and Aztek's intangibility could allow them to take out the regs. Now, if Aztek attacks Alice, she can steal from him. But then she's left with only Aztek's powers, and wouldn't stand a chance against the ubers. So she probably wouldn't. In the end, I think Ari's final 3 are just a bit more powerful than LV's. Especially with the speed they have.
Although I do have to say that the thought of SMP ripping his own head off made me laugh. And, yes, you should have called Morrison.
