I have been loving all the chase figures so far but I was just wondering what would some really good ways to use Thor Frog of Thunder? What have people been doing out there when they use him? i.e. feats to consider, support pieces that he would benefit etc etc.

well...if someone would like to give me one, i would definitely give a more constructive post.
sorry just tagging so i can see the options myself.

Sounds like this belongs in the Combat Formations section, but I'll give you a possibility.
Build this Non-Theme team:
Frog of Thunder 72pts.
Tempest 116pts.
Triton 72pts.
Aqualad 40pts.
300pts.

You gotta bring the Opened Hydrant, Ariel Baffler and Structural Integ. feild as your objects. Tempest creates Water witin 3 and so does the Hydrant. Place the Baffler and the Hydrant next to the SIF so they can't be shot. Frog, Aqualad and Triton all have "stealth" when in water. KEEP 'EM IN THERE! The enemy can't shoot you so they gotta come in the water to base you. Triton and Frog can do free Damage to anyone occupying water. The Baffler prevents fliers from landing near you much less anyone they were carrying. Not an unbeatable team, but a pain in the @$$ for sure!

The bolded is illegal. The Structural Integrity Field only prevents wall and blocking terriain from being destroyed. Objects are fair game.

WHOOOPS! Buzz-Kill! Forgot about that. Well I guess Tempest will have to Barrier while Aqualad and Triton Charge to Base Enemy figs.

He's got the right idea, though. I'd try something like this:

HA100 Thor, Frog of Thunder
116 CR047 Tempest
72 SI037 Triton
5 IOF001 Submerged
27 HT052 Aquaman
5 IOF001 Submerged
3 SIF006 Alias

Put those submergeds on Aquaman and Tempest, so none of them can be shot, that way Tempest takes the place of the hydrant, and no one can see him to outwit his powers. Alias on Tempest, just in case. Let people run up and start wackin' away.

Here's a larger version of the same theme:

HA100 Thor, Frog of Thunder
116 CR047 Tempest
5 IOF001 Submerged
150 SI045 Namor
5 IOF001 Submerged
12 MMF001 Automatic Regeneration
72 SI037 Triton
40 CR004 Aqualad
10 AWF007 Armor Piercing
10 AWF007 Armor Piercing
8 MUF102 Protected
500 points

Armor piercing on Triton and Thor Frog, Submerged on Tempest and Namor, Auto Regen on Namor. Same idea, let them come to you, then pound the hell out of them. Keep Namor in that water so if he gets too much damage at the front line, he can Regen for free. Triton and Thor Frog become pretty deadly with AP on them, as their attacks do auto damage, especially good in close quarters. Protected on whoever. And yeah, don't forget that Baffler so Namor always gets to charge in for the first shot.
