Does Earth Man's damage power stop Quasar from using his white power that gives him Phasing/Teleport?

Quotes... good!
Since Phasing/Teleport is a move action it is not affected by No place to hide.

NO PLACE TO HIDE, ALIEN!: Opposing characters with the Cosmic keyword can't be given power actions to use standard Speed powers. Those characters modify their defense values by -2 when attacked by Earth Man.

QUANTUM TELEPORTATION: Quasar can use Phasing/Teleport. When he does, if he moved 5 squares or less, after the action resolves he can make a ranged combat attack at half range as a free action.

PHASING/TELEPORT Give this character a move action and move it up
to its speed value. It ignores the effects of characters and terrain on movement.

based off the wording of the 2011 PAC I would say that NO, Earthman does not prevent Quasar from using his White Power. Why? Because Earthman's white power states "can't be given POWER actions" where phasing teleport is a MOVE action.

beaten to the punch, and yes Quotes are very good!

It may interest you that Phasing wasn't always a Move action. In older PACs it is defined as a power action so be sure to have one handy.

Are you suggesting that a player should have an older PAC with the, so that they could claim that P/T is a power action and prevent it with Earth Man?

No what he's suggesting is that Judges should be up to date, see right through that tactic, and toss his arse for cheating. As enough time has elapsed since the PAC change that every player should have the most current version by now

No, I was suggesting that you have the newer PAC so that when they show the older one where Phasing is a Power Action you can show them the err of their ways.
