Could the Sun-Eater be considered for this list? You'd struggle to find a more powerful item than a nigh-invulnerable cloud that devours suns and can only be killed with the death of a major character.

It is a bit suprising to put on the same list common Spider-Tracer and items of unlimited power, like Infinity Gauntlet. :D

@incadeptus: That's a fine idea! Thank you much!!!

Hey, dear. I think that you should add Doctor Fate's helmet :D

@mynamewasdeleted: Thanks! I'll get those added in when I get back to my laptop!

here's a few more for you:

SCUD (you could put him in right before the Terminators)

Kevin Matchstick's Bat, which should go in your list right after Excalibur.

Also, the Grendel Fork and Daredevil's Billy Club deserve a place on your list (probably right after Batman's gear)

@betatesthighlander1: I'll add the Ultimate Nullifier now. I didn't add it because I didn't think of it and no one told me...until now. :D

Thanks! I like to have lists worth looking at.

this is an amazing list, Bravo

(nice to see someone else who read Lady Death)

but why no Ultimate Nullifier?

@luke_kerridge: I do not disagree about the symbiotes, but I didn't have a list for them so I stuck them here. Maybe I should start a list of "Powerful Suits" or something. Iron Man, War Machine, Symbiotes, and so on? Hmmm...

Very good list, my only criticism is that I don't think the Symbiotes should be in here

Wow. Impressive list.

I don't know when you made this list, but it is extremely well done.

humm i wonder if Brainiac is a weapon

Great List  :))

Thank you.  Let me know anything I'm missing.  There's plenty I'm sure I didn't think of.
