Far-fetched as some of ZopZop's claims appear to be, he does bring up a few good points. Beings such as Odin and The Celestials are obviously light years away from that off human beings, cyborgs, etc. They're in a different league altogether. So, yes, when a member of the Council of Reeds takes out a Celestial with an entropy gun, it's hard not to notice. I understand that the entropy gun is one of the most powerful weapons in existence (it would certainly have to be); that I take no issue with. However, in the hands of Reed Richards, a mortal man, it's difficult to imagine how such a weapon could destroy a Celestial. Think about it for a minute. These aren't mere giants; they're intellectually superior beings. It should take no more than a snap of the finger to rob Reed of his superweapon and warp the entire council into frogs. That's exactly what Ashema did to Thor back in the Heroes Reborn: The Return limited series. It's just a little baffling. So when you ask, "What makes you think the 3280 Celestials aren't quite on the same level with their 616 counterparts?", well, there's that for one. Aside from the latter, I find the behavior/demeanor of the 3280 Celestials to be quite different than what we're using to seeing from Arishem and his boys. With the Earth 616 Celestials, you get the feeling that they're invincible; whereas, the 3280 breed appear to be somewhat more vulnerable.
Having said that, I get what Zop is saying when he advances the claim that a Council of Reed member, armed with a super-weapon or not, would have a hard time taking out Odin. It just wouldn't happen. Reed wouldn't even get the chance to use it. Odin is, not only one of the more powerful cosmic entities in the MU, he's also one of the wisest. He's a god for crying out loud. My thoughts.
