[Marvel/DC] Out of the various super-teams, which ones would actually have you concerned from a security standpoint?

Let's say your taking the role of an operative of ARMOR or some similar organization. For those who don't know what ARMOR is, it's an arm of SHIELD that focuses on observing alternate realities.

So out of the following Super-teams, which do you think is the most dangerous in both terms of power and any psych profiles you can gather on said team members:

Justice League (Assuming that it's only made up of the 7 founders)

Avengers (The 6 original founders from the comics plus Captain America.)

X-Men (Only the team members that we see in the 90's cartoon)

Fantastic Four (Only the original four)

The Bat-Family (Includes all the previous Robins and any of the previous Batgirls but NO Batwoman or anyone else)

Edit: The gist of the question is: "Which super-team would be the most likely to go rogue and how dangerous would they be?"

All of these teams present an end-of-the-world level threat if they went bad, so the one that worries me most is the one that would be hardest to stop.

That is, very easily, the Justice League. Of the original seven, Superman, Martian Manhunter, and Wonder can end the world individually, and all are extremely difficult to damage. Green Lantern isn't quite at their level, but he's close. Flash, if he was using his powers intelligently, is nigh impossible to contend with. Batman, despite being a mortal, has the capability to killing all of them, which puts him at a very high danger level, as well, because if a guy can kill Superman, there isn't a whole lot that will stand in his way. Aquaman is the least dangerous of the seven, but he is the King of seventy percent of the earth.

The Bat-Family is second on this list only because Batman is also part of the Justice League, and if the entire league goes rogue there are no contingencies that will be effective. The Justice League *is* the contingency for Batman going rogue, so there's at least a chance that the Bat is taken down if it's just him and his various Robins.

The X-Men are next on the list. Again you have a number of individuals who could end the world solo; Xavier with Cerebro could mind-flay the planet, and Ice Man could turn the entire world into a 0-degree Kelvin wasteland. You've also got a chick who is prone to becoming the avatar of flaming, psychic destruction, and she's dating a control freak and the least polite Canadian on the planet. However, there are technologies, like Sentinels and anti-mutant manacles, that can slow them down or stop them outright.

The Fantastic Four are the next most dangerous, primarily because of Sue's force fields, which are nearly impenetrable, and Reed's technology, because Reed can ass-pull a planet killer if you give him a tin can, a ball of twine, and twenty minutes. Still, you've got guys like Tony Stark and Victor von Doom who would be able to give them a real problem if things went south.

The Avengers are probably the least dangerous. Thor could kill the earth with his Godblast, but aside from that the most directly dangerous is Hulk, who's a city-buster under most circumstances. The real danger is Tony going bad, but then you're looking at a dictatorship, not an end-of-the-world scenario.
