Ok so i was siting there reading the FAQ and thought of this, if i mind controled a 2000ad fig, could i choose to use their TA on like a character of my choice? i think that would be great, making it on like a generic! so is it possible?

I think that it would be possible, since you are allowed to use anything they have to your liking. But it won't if they have already chosen an enemy for that ability. Because even though it may have switched sides, they ability can only choose once.

The 2000AD team ability lets the player choose a character or team for all of their 2000AD team members. So here's the scenario:

If you have a 2000AD member and select a target that only applies to 2000AD members on your force.

If I don't have a 2000AD team member but I MC one of yours I can declare a target for the 2000AD team as it is now declaring it for my force.

If I MC your character again then my declaration still stands and I get the bonus for that target still.

So it's declared by a player for their force.

That probably didn't make too much sense as I'm pretty tired.

So after all that being said, if you MC your opponent's 2000 AD character, declare whoever or whichever team to have that +1 damage on, is your opponent stuck w/ that choice for the rest of the game or can your opponent declare another person/team to have the increased damage?

In that case your force is "stuck" with that target but your opponent still gets to choose (or keep their choice) for their force.
