Totally see that, and maybe I am just being thick.

Do you see a difference between Nemesis power as stated, and say this example: "Nemesis can use Pulse Wave with full range and his printed damage value is locked."

To me, the first says, "Nemesis can use Pulse Wave. (Period)" Then goes on to list a limitation. The other states Pulse Wave and it's limitations in one go, thereby making it something different than PW.

Again, am I just thick? Reading into this too much?

If so, please say, "Bugle, don't be daft."

I definitely see where you are coming from, but I think this is one of those things in this game. If you see the words "can use" and the name of some other power, you are good to go (no matter what any other words in the power say) .

Mobius Chair is not providing the use of a modified form of any SP's, Mobius Chair simply limits HOW MANY of those 3 extra powers can be used per turn: 1.

Sounds cool to me. Thanks for the input, but you guys did not call me daft!

Now I have to hit myself in the head with a 2x4 before I go to bed.

(must...be...punished...)

Hmm... If In-Betweener copies powers from Metron, Metron's controller can say which of the three powers granted by Mobius Chair IB can copy.

This is because Metron can use only one of those powers per turn and IB can copy only those powers the character can use. If Metron is using Leadership, he can't use Perplex or Support etc.

Except Metron won't "be using" any of those powers when In-Betweener is acting, as In-Betweener won't be using POA on Metron's turn. Metron will be able to use all those powers at the time POA is used.

Mind you, you're on to something. For example, if Ultraguy has "Ultraguy can use Probability Control, but only on his player's turn.", In-Betweener will not be able to gain Probability Control by POAing Ultraguy, because Ultraguy can not currently use PC (it's not his turn).

Similarly, if Ultraguy had, "Ultraguy can use Impervious, but only if he has no action tokens on him", when he has action tokens on him, and POA is used, In-Betweener won't be able to borrow Impervious (and the number of tokens on In-Betweener is irrelevant).

This sounds like the Earth man argument all over again. Wait, would that mean Earth Man can use one of the Metron POK powers without penalty as well? I love that figure more by the minute.

Yep. Quake, Psychic Blast and Pulse Wave are all standard attack powers, so Earth Man would able to use one of them.

Same with Rogue:

But not Gideon, because his borrowing power requires possession:

Look at Mobius Chair again: "Once per turn, Metron can use one of the following powers: Leadership, Perplex, or Support."

The fact that Metron won't be able to activate any of these powers on IB's turn does not change the fact that Metron can only use (in the HeroClix sense of the word) one of these powers per turn.

So when it is IB's turn, Metron can use either Leadership, Perplex or Support. He can never use them all at the same time, so IB can't ever copy them all.

I think you're asking the question incorrectly, though.

In-Betweener copies the powers Metron can use. We know that if the powers Metron can use changes (if he takes damage), In-Betweener will have different powers, so his powers are a constant reference to what Metron can use.

Can In-Betweener use Leadership? Answer: If Metron can use Leadership, which he can, since Metron hasn't used any of his other powers.

Can In-Betweener use Perplex? Answer: If Metron can use Perplex, which he can, since Metron hasn't used any other powers.

Can In-Betweener use Support? Answer: If Metron can use Support, which he can, since Metron hasn't used any other powers.

Metron is the only one the restriction applies to, and Metron isn't going to trigger his limitation at any point on his turn, so In-Betweener will always have access to all three of his options.

Oh, and I love the avatar, bugleboy!

I think that you are thinking about it backwards.

The power is not "Metron can use X, Y and Z. If Metron has used one of these powers, he can't use the others."

His power says that in a given turn he can use one of those powers. Not all of them, only one.

Or trying to put it more clearly:
Every turn, Metron has to choose one power he can use. He can never use all three of the powers, so IB can never copy all three of the powers.

It doesn't matter if Metron can use all three in a single turn-- he can use all three. Polar Opposite Attack has no limitation requiring the borrowed powers to all be usable within the same turn.

Supergirl has HSS and RCE on her second click. She cannot use both in a single turn. However, Polar Opposite Attack would allow the In-Betweener the use of both powers.

There is a very simple test to see if IB can borrow a power. Is it a standard power? Can the target use that power? If both are yes, then IB can borrow that power.

When I say use, I mean use in the HeroClix sense of the word. Supergirl can use both HSS and RCE on the same turn. The fact that she can't activate them both on the same turn has no bearing on this matter.

Metron on the other hand can use (again, in the HeroClix meaning of the word) only one of the powers granted to him by Mobius Chair.

It's the same thing as with SI Namor's Aquatic Rejuvenation. If Namor is not it water, IB can't copy Regeneration from him.

On any given turn Metron can use (HC use) only one of the three powers given by Mobius Chair, so IB can only copy the one power he can use on that turn.

I understood the term "use" in the same manner. Regardless of the fact that Metron can use only one of those powers on a given turn, however, Metron CAN use any of those powers; and the In-Betweener's Polar Opposite Attack allows him to use any standard powers that his target can use. The once-per-turn restriction of Mobius Chair is irrelevant.

Namor's Aquatic Rejuvenation is different because, if he is NOT occupying water terrain, he CANNOT use Regen.

Again, the test is simple. Is it a standard power? Can the target use it? If yes to both, In-Betweener can borrow it.

Both Namor and Metron have pre-requisites to how they can use their powers.

Namor can use his power ony in water.
Metron can use only one power per turn.

How are they different?

But there is never a situation where Metron can use all the powers given by Mobius Chair. So the answer will never be yes to both questions when IB is copyng the powers from Metron.
