I have questions regarding these SP.

First, Seth says this about the Cuckoo...

However, when one is carried, they CANNOT take an action. The Cuckoo coordination SP does NOT mention the carried sisters can take actions.

I mention this because of BOX's SP (vs nanobots).

Nanobots SPECIFICALLY mentions you can only use adjacent objects, not carried by others.

So....

1 - The second and third CUCKOO's should *not* be able to act after they are carried, yes or no ?

2 - If yes, why? Because the SP does *NOT* mention this, and it would be against the General rule.

3- If the answer is still yes, then why cant BOX "nanobot" carried objects. Since HIS SP is NOT LIMITED as the nanobot feat is. (also note since Phantom Girl can affect carried objects, the game mechanics could allow BOX to).

Seth probably got carried away and forgot himself when he wrote that. Unless an errata is posted, the Cuckoo's CANNOT act after being carried.

And no, Box CANNOT "nanobot" an object carried by another character. Objects carried are considered to be "out of the game" and are not adjacent to other characters.

Answer by Seth:

Is Cuckoo eligible for Mental Shields? The text says she can use Mind Control, but is that the same as having Mind Control? How about if somebody tries to outwit the SP?

Special Powers do not count for meeting the prerequisites for feats.
As Cuckoo has neither Mind Control not Willpower, she cannot be assigned Mental Shields.

I was really excited about Cuckoo before Seth clarified the movement question. Thought we were getting a TK alternative! Oh well, it should still be fun.

I've got some questions that relate to both as well, namely, what do they mean by "once per round" or "until the end of the round"? Is that the same as "until the beginning of your next turn" or is that like "until time expires or one person has no characters left on their force"?

And also, do you still get the +1 if Cuckoo's die or are no longer adjacent?

Until the end of the round means until the beginning of the first player's turn.

It lasts until the end of the round, as long as the one with the bonus keeps the special power.
