As a few comments in the units section have mentioned, I'm unclear on how ACWW will interact with a HSS attack that deals 3 or more damage to a friendly character. As per Uatu's trait:

It sounds like Uatu would be placed adjacent and give the token in mid-HSS attack. If so would the attacker then be able to complete the rest of that character's movement if they have any?

Yes, they can. Push damage occurs after the action has been completed. Or, more specifically, it's part of the action resolution. But tokens might be added at any time.

So it isn't the giving of the 2nd action token that causes the pushing - it's more like a check at the end of a character's action to see if they now have 2 tokens when they would have had less than 2 at the beginning. Is that about right?

No. It is the second action token that causes the pushing, but the pushing damage will not be applied until the action resolves.

There are possible scenarios where a character could receive a second action token and then lose the second action token, but it would still take pushing damage as at some point a second action token was placed on it.

Why wouldn't the Watcher just be placed next to the attacker AFTER the HSS attack has resolved and the attacking character is at his final square for the action? It seems like that was the intent to begin with.

Because very rarely are you in the final square of HSS when making the attack and Uatu's power activates when a friendly takes damage, which is still in the middle of the action.

Well, more so I was getting at the point of mid action interruption.

I thought you could not have any figure do any actions during the current action of another figure?

Plus to me, it would seem a bit more tactical to place Utau near the enemy at the end of his movement so he could do something next turn.

Uatu's power does not require an action at all. It happens when a friendly character is dealt 3 or more damage from an attack. This means that it will always happen during an opponents action.

Also, it is possible to make an action during the current action of another figure. Big Figure can cause this to happen as can Wrecker and most likely other figures too.

Whether or not something is more tactical has nothing to do with the rules.

mmm, okay...
And yeah, I know the Tactical "thing" is not a valid reason for my rules point, i was just saying that if I were playing as Uatu, I would rather be at the end of the movement.
Which I guess causes me to ask another question.
So Uatu is placed next to the attacker right after the damage is dealt. SO then, after Watcher is placed and the attacker is able to move with the rest of it's movement, I assume Watcher is still left in the area where he was originally placed after his power activated?

You can't, unless something specifically tells you that you can. There are very few game effects that do. (SHIELD TA used to work this way, but they have streamlined that so it no longer does, and is much easier to understand as a result.)

Note, however, that Uatu's text in question isn't an action. There is nothing in that game text about his movement being any kind of action, even a free action. It is just something that happens, not an action at all.

Yeah, well, I'd rather my dice always came up 6's. : - )

Yep. He's not clingy!

^^LoL, you always have great answers, sir.
But now that I now this, let me throw this meatball you way...

BLACK TARANTULA
MANY ARMS OF THE BLACK TARANTULA: "Give Black Tarantula a double power action. Give him a close combat action as a free action and he may use Blades/Claws/Fangs. After that action resolves, he may automatically break away and move up to 2 squares and then may make a ranged combat attack."

So BT does the initial Close Combat Action, causes damage. So then at that point Watcher is placed next to BT. THEN, BT does his break-away move. Now, can BT target Watcher with his Ranged Combat Attack? I figure so, but just want to make sure...

Sure, nothing in Uatu's power prevents him from being attacked.

Big Fig + Darkseid say otherwise.

Care to explain?

I don't know why Darkseid is listed. But, Big Figure allows for situations where you can give actions during an opponents turn.
