Exp. Vertigo is the way to go. She's pricey (Incap for almost her whole dial will do that), but triple shot, Perplex, a solid AV (she only needs a 6 to hit Thor), and Super Senses provide a very solid package for the points. If you get the chance, have her Perplex her own range - no one ever seems to see that coming...

An idea that has been bounced around on HCRealms a few times. Problem would be the lack of punch through against Impervious/Invulnerability.

On the other hand, 14 Rookie Dominos forcing endless rerolls, and then ending the mix with Super Senses, would be enough frustration to make the baby Jesus cry.

How about mind controlling Thor and bringing him where yhour figures are concentrated, preferably adjacent to a figure with Plasticity.

A good figure to tie in Thor is Metallo because of his exploit weakness. I once MCd Thor and brought him adjacent to Metallo and Spiral, who together then had outwit. I then started pounding on him with all I got till he got KO'd the following turn.

I have to go with the Incap team people. If he never gets to take an action what good is the best character. My choices for this:
1. V or E Green Arrow, If he is using Ultimates Thor the stealth doesn't do much good but GA's attack values give you an excellent shot at hitting him. The E also gives you JLA free move for wildcards.
2. REV Vertigo, three for one. Gotta love that trade.
3. V Nightwing. All this and you get Outwit too!

Medic Hunters. The idea is cheap disposable but hard to keep away from.
1. Sidewinder - Serpent Society phaser with 14 speed in the V version he isn't going to be able to run. Super Senses occasionally let you dodge, and that Leadership comes in handy. All for 35 pts.
2. R Hawkman - Just get within 5 (4 if soaring) and you can charge. At 32 points you can afford two for one V Jessie Quick, (a good piece but better for doing other things than chasing medics). Free movement means you don't have to use valuable actions until attacking. If you are using an outdoor map you can move to soaring level to avoid the crowds (and halve all ranges including Outwit!) then dive bomb your opponent.
3. E Hawkgirl - See R Hawkman but faster due to Willpower alowing you to push without damage. Just a bit pricer at 39 points but you get 6 range. Her big detriment is she is not a free mover.

The last method I view as cheese but if you are just out for blood ...
Wild Card Abuse.
Doombots + Yukio (Crossgen) or Circie (Mystic) + Kabuki or Batman team (robin is cheapest) + Skrull Team + JLA/Brotherhood/Avengers + Superman Enemy (Intergang Medic, extra points but are you really going to need a medic after 7 clicks? Or just a call to the morgue? So why not get one that will do something else for you)

For TK use Cosmic Boy, to mimic Crossgen.

I think you get the idea.

Just remember you can only use one team ability in an action, No free move phasing by combining Avengers and Serpent Society.

The Domino Delivers team with a bunch of Armor Piercing cards could make a VERY interesting team.

You would get your guaranteed 1 click damage through Imperv/Invuln. And that would be enough to knock Thor off his Imperv click.

It would make your point total go up, but maybe then you only have 12 Rookie Dominos instead...

if dupes are allowed:

9 mj pgs 45
V Green Lantern (Hal) 165
Alfred pog 6
R Mandriod 28
Security Guard pog 6
E TaskMaster 58
R Intergang Agent 18
U Spiral 56
U Boon 58
E Hawkgirl 39
Trickshot for Hal 20

Surround hal with the MJ clones,use mandroid and hal to double launch a bcf'er into Thor's face as much as possible, or a MJ clone. If Thor has trick shot and/or TK help keep Hal well out of range and send in the clones to tie Thor up, they can't all get incapacitated. Use hawkgirl to get rid of the support. you might want to change hawkgirl to a JLA member so all the clone pogs get free movement. Once the MJ mystics have worked their charm, clean up with Hal.

I would almost think going forward that Overconfidence is actually the way to go against this team. You don't want thor getting 2 more range or 2 more damage. Just make sure there's a side squad, or even just robin with pounce, to take care of the medic.

I definitely think you need Mastermind or SS to avoid, not reduce the damage, and either lots of incap (since there's only 2 attackers) or Mind control. I would say V Nebula & V Mandarin. If you play overconfidence you can always outrange him. Then MC thor to take out his own support, turn off his defense and smack. Thor will still need a 7 to hit Mandarin off the bat more times.

I also like the all crossgen idea. A couple hits off that and thor will be off running shot and black adam off HSS.

Field two TK peices and 2 Vet Ult spiderman with pounce and a superman enemy TA fig.

Tk out the two spideys, they both copy the TA to outwit his imperv, they pounce, one with the soda machine the other with the light post.

No more Thor,,, If they both hit.

Vet ultimates SpidyX2 - 116
R Jean GreyX2 -62
R intergang medic -20
Pounce X2 -30
KC Superman-265
Alfred Pog - 6
TOTAL - 499

This is my team ( with this I have defeat thor with no trouble):

V Green Lantern (unleashed) + trick shot
U Despero
V U Man x3
V Scourge
