It's been a while since I used this, and I'm not sure if anything has changed or whatever, so I thought I would just waste everyone's time with an oldie:

When I successfully Mind Control more than 1 person, when do those figures become part of my team? If I mind control 3 people, do they immediately become part of my team and then one by one as I make their actions they return back to their owner? If this is the case, can I not attack a newly Mind Controlled person with another newly Mind Controlled person before they have been given their action? I do know that a newly Mind Controlled character can carry another newly Mind Controlled character, and then the carried character can make an action due to it being free and all, but I just wanted to make 100% sure that I have this right before I play my MC team.

Immediately.

Yes.

You cannot. As long as they're friendly to your force, they can't attack each other.

This is just a great (though nasty) tactic. The carried character could attack the taxi after the move (but not before).

That's what I thought, but I just wanted to make it clear. I like to build crazy teams (3 are listed in the link in my sig) and I tend to test them out on each other, which isn't that great an idea considering none of them are really balanced, but I still try to figure a way for my teams to beat each other anyway. The team that usually wins is the GL Turtle, so I was trying to figure out what tactic my Hard Traveling team should take it down, and I figured that if I can hit them from elevated, GA should Mind Control Hal and two Detectives, carry the detectives away from the turtle then try to hit one of the Invisible Girls. After the initial attack, the Detectives should take swats at GL, and even if every (post MC) action fails, GL will still have to use his action to get back to his turtle and will limited to who he can target. If any of that post confused you, especially about GA MCing, you should read the link in my sig.
