It is, but there seemed to be some argument as to whether a GL ring was magnetic. The argument that being metal is enough to be magnetic is a bad one to make.
Whether the GL ring is metal at all seems to be the better debate, though most of the League have fought Doctor Polaris before and fared relatively well against him, so Magneto's impact is up for debate, in all fairness.
Mags was able to lock onto Kitty Pryde's unique EM signature even though she was inside of an Intergalactic Bullet that was moving in hyperspace (which is WAAAAAAAAAAY faster than MMMMMMFTL.) at least a galaxy away. He did this before the High Evolutionary's long range scanners/sensors even sensed the bullet.:
at base levels, Mag's reaction time is 15Xs faster than a Normal Human. By tapping into magnetic fields, he can amp this to well over a million Xs faster. Stark learned this the hard way when he used millions of magnets against Magneto. Here's the scan where his reaction time/thought process time was amped up over 100,000Xs faster
that feat of Superman is nowhere near lightspeed. - I've calced it out, and while it is FAST (stupidly, ridiculously fast), one could do it considerably under lightspeed. Like, a lot.
What makes me laugh in that scan you have above is Clark talking about it buying her an Attosecond. Clearly the writer has no idea how minute amount of time an attosecond is. It's stupid, because the bullet is basically frozen if we're counting Attoseconds (and will be frozen, essentially without getting anywhere, since it is travelling roughly 2.8E-13 MILLIMETERS in an attosecond, which means if it's 5mm to her skull out of the barrel of the gun (I think it's 10mm, but let's go with 5), it'll take the damn bullet ~17 800 000 000 000 attoseconds for it to hit her skull (<-- some numbers here might be off, because this is a quick and dirty calculation, but you get the idea). So her 'buying an attosecond' is somewhat meaningless, here. And smells like BS.
Also because Clark doesn't do stuff in 'Attoseconds'. He's not THAT fast.
And if he was fast enough to work in attoseconds? He could have sat down, read a book or five, left to go pick up something on the other side of the world, come back...and the bullet still wouldn't have appreciably moved further in its journey.
Your scan shows Magneto using his magnetic counting powers. Not his reaction speed. He didn't actually sit down and count them like you or I would.... lol. So I guess if this was a counting contest maybe?
Lol.
1. Nobody said it was lightspeed. So your reading comprehension, Mr 1,000,000 hard light metal, is way off.
2.writers not knowing stuff is...well, par for the course. I can sit down and tell you how writers don't know Jack about genetics, and how mutations in your DNA don't mean you can control the EM spectrum, let along control the weather, but hey ho.
3. 'i don't like it, so it doesn't count'. Great arguments all round.
That's a fast bullet. We rent see any fire from the shot and an attosecond later. fire is coming from the barrel. That must be a back to the future gun.
I was thinking the same.
While you’ve gotten involved in a Speed discussion, the JLA have other BFR options, and the ability to whittle down the mutants till its team vs one or maybe two.
So can Susan Storm. So that argument has zero relevance. Unless you want to argue that MAgneto (with 15x human perceptions, as you pointed out) is light speed? So light is 15x human speed? OK.
That's like saying none of the attacks Hulk tanks are all that impressive, because his pants are still intact in all the artwork.
So a stupid argument.
@riv: yes, I agree. Speed is one thing - it's speed backed up by the offensive capability to capitalise on it.
