1) Tempesta's MBP didn't just spread out, it fed on Ethernano and contaminated it. It was like a virus. Keith's MBP didn't do that. Otherwise this would've happened after just one attack from Keith -> http://img4.mangasee.co/series/FairyTail/0358-016.png

Laxus cleared a whole area filled with both Tempesta's MBP and' contaminated Ethernano by forcing it into his lungs. Juvia at best swallowed some of Keith's MBP while she was inside of him.

2) Tempesta's MBP didn't multiply but it contaminated Ethernano which Keith's MBP wasn't shown to do.

The way I see it, Keith's MBP did vanish. I've given you a few images that show just that.

3) He couldn't reform his body afterwards because Juvia materialized inside him and forced his body to break. You can see Keith's bones flying all over the place in that image.

That black mist that bursted out of Keith's body was MBP. If it wasn't MBP, what was it?

4) Keith's MBP didn't contaminate Ethernano. If it did, then all he had to do was attack once and watch the MBP knock out everyone. But instead, even after he attacked Juvia multiple times and released MBP, this -> http://img4.mangasee.co/series/FairyTail/0358-016.png never happened.

If Keith's MBP could feed on Ethernano and contaminate it, why didn't he let it spread? Just a bit of it would be enough to knock everyone out.

5) This -> http://img4.mangasee.co/series/FairyTail/0394-012.png was still connected to Keith's body though. After he thought he won, he reformed back to his original form. This -> http://img4.mangasee.co/series/FairyTail/0394-006.png wasn't connected to Keith's body, so he couldn't retract it.

6) Keith's MBP didn't contaminate Ethernano in the air like Tempesta's MBP did as soon as it was released. While both Tempesta's and Keith's MBP may be equally lethal, they don't work the same way. Imo at least..

7) I said that imo, Tempesta's MBP and Keith's MBP were basically the same stuff but they didn't work the same way. Tempesta's MBP contaminated Ethernano in the air when it was released. Keith's MBP didn't.

Well, if Levy didn't treat them and everyone got up just a few minutes later as if nothing happened, it means both the poison inside the Tenchi Kaimei and Keith's MBP weren't even close to being as lethal as Tempesta's suicide attack. Which would make sense, actually...

8) Well, I don't know Japanese, so I can't translate anything on there. Wish I could though.. But I do know Sayla has a spell that is 4000 and Kyouka has a spell that is 2500.

And it would make sense for Sayla to have stronger offense than Kyouka looking at their feats. Kyouka's main offense is her claws, which Erza could take plenty of and continue on fighting just fine. Sayla, using an unnamed attack, literally knocked the Sitri out of Mirajane.

9) Juvia didn't take in all of Keith's MBP. In the image I gave you, you can clearly see Keith's MBP bursting out. And Laxus forced as much MBP and contaminated Ethernano into his lungs as he could. All of that poison just sat there in just one part of his body for more than a day and he still made a full recovery just a week after he has been treated. I view that feat way more impressive than Juvia's tbh.

You're free to think otherwise of course. I ain't stopping you...
