I have a couple question about White Martians. 
Are they more powerful than Green Martians?...Do they have different powers? 
How powerful are they compared to Green Lanterns? 
How many can Superman take?...Martian Manhunter?...Wonder Woman?...Hal Jordan?

@Clark_EL: They're basically the same as Green Martians, just evil. That's really about it.

I'd recommend checking out the Hyperclan. That should answer some of your questions. :)

@Clark_EL:Superman, Wonder Woman and Green Lantern may be able to take them on physically if the White Martians dont use their intangibility (unlikely), but the heroes would lose mentally only Martian Manhunter can stand up to them mentally. They can beat green lantern's because their constructs don't usually hit intangible opponents

Hey thanks for the replies, do white martians actually use their more powerful abilities(intangibility, and Mind attacks)?

@dondave: Wait do they use their more powerful powers, or not. To me I would assume they are less intelligent than Greens considering that they won the civil war between them, and their more peaceful ways would mean they would think things through more, right?

Oh why does this have to be about COLOR? Aren't we more enlightened than that now?!

LOL!!! Sorry, I couldn't resist...

@Clark_EL: They use they use there powers equally as a green martian would but they are geared more towards violence, there are not less inteligent they are quite smart like an evil dicatator

@dondave: Oh, so how did the green martians win the civil war.

@Clark_EL: I don't think they did. I think they all died out before there could be a winner

@Clark_EL: My bad, the civil war between the two races ended when the few surviving White Martians were rounded up and exiled to the extra-dimensional "Still Zone"

@dondave: Do you know how many green martians were left after?

@Clark_EL: It doesn't specify in the comics but they all died anyways

@dondave: So how many white martians can John take?

How about Ma'alefa'ak?

@Clark_EL: there isn't an exact number but during Terror Incognita 9 white martian who had been upgraded telepathically to the point that they could use it across light years couldn't get past his shields. He telepathically tricked them into fighting each other by making them think the other martian was a member of the justice league

@dondave: Ok thanks

Also white Martians are faster and a bit stronger, they have a few more powers including Martian vision (laser eyes). It is really cool too
