So, if I Outwit the Flight Ability, would said character be affected by Major Earthquake?

I'm just not seeing how.

Wouldn't outwitting the Flight ability mean they can't USE it? I would think if it were outwitted then that figure would be affected by Red Hulk's power since it says:

Of course I tend to have to double check rules on things because i'm still semi-new but I wouldn't argue if someone did it to me because it seems like it would work.

To me, it only means they cannot ignore character nor hindering terrain but are still "flying" per se, so they'd miss the Major Earthquake.

Or is Outwitting Flight considered equivalent to turning a flier into a non-flier?

When you Outwit the Flight ability, they gain Earthbound, which gives them the Boot Speed Symbol, thus making them subject to Red Hulks SP.

Yeah, I'd say outwitting Flight makes them susceptible. It doesn't say "Characters that HAVE flight", but "Characters that can USE it". Can't use it if it's Outwitted.

that isnt quite right...your only outwitting the flight ability (you cant outwit symbols) so they'll still have the carry ability that the flight symbol provides,where as Earthbound/Neutrulise takes away all ability symbols (indom,flight etc) and replaces them with standard abilites symbols.

Because the power specifies "characters who can use the flight ability" and not "characters with the or ", the characters would be subject to damage from Major Earthquake if use of the flight ability is in someway countered or lost.

Right conclusion, but wrong reason.
Jim is correct here. That distinction between gaining earthbound or losing the flight ability was important in one of my games tonight--I was using Thor's Mighty Chariot, and the the other player played the crosswinds bfc.
original wording:
current player's guide wording:
I made sure we checked against the player's guide, because using the original wording, my chariot would have lost his , , and symbols, which would have had a significant impact.
I still lost, though.

Awesome, satisfactory for me then!

Thanks y'all! (yes, I don't need an Orange Ranger, we're all agreeing with each other, which is good enough for me)
