Okay so Hawkeye has Energy shield deflection and he's on a rooftop aiming down at Kilgrave the Purple Man who is attempting to M/C him to shoot the heroes who are closing in on him. Is Mind Control considered a combat attack since it's a speed power?

It is considered a ranged attack, but not because Mind Control is a speed power. It's because of what Mind Control says to do (note the underlined portion of both powers):
Mind Control allows the targeting character to make a ranged combat attack that behaves differently from a normal attack. However ES/D doesn't say that it only works against a normal ranged combat attack, it just works against ranged combat attacks. So it would work against a Mind Control attack as well.

Yes it is. Mind control gives either a close combat or a ranged combat attack as a free action with no damage so Hawkeye would get +2 defense against the ranged attack from his Energy Shield / Deflection.

i concur.

thanks, Rob

p.s. how do you copy paste from the p.a.c.

But the reason I wasn't sure is, does Mind control qualify as a Combat attack? it is a speed power and not an attack power after all.

it doesnt matter what slot the power is on, if it allows a combat action/attack (where the dice are rolled etc) then it is a Combat attack.

e.g Malekith has Psy blast as a defensive power, or something silly like that.

it doesn't matter, where on the dial a power shows up, all that matter is the wording in the Powers and Abilities Card.

I just mark the text in the PDF reader and copy it. If you cannot do that, you probably need a better reader - I'm using Foxit.

Okay, I'm convinced.
